Wag on a wall – servicing a well engineered movement

This wall clock was gifted to me in the spring of 2022. I have no idea who made the clock, there are no markings on the case or the movement. It was likely sold by the Forestville Clock Company of Toronto in the 1960s and my guess, a Hermle movement. I could find nothing else about it online. I wrote an article in August with first impressions.

The style of the clock is a “wag on the wall”. It is a strange name but basically describes what it looks like it is doing, wagging its tail. A Wag on a wall clock is a clock with the movement enclosed in a small case with a pendulum and weights exposed.

From 1660 to about 1870, the wag-on-the-wall was a very common clock style. It is so named because the pendulum appears to wag on the wall like a dog’s tail. It is also a derivative of the English lantern clock (more closely to a converted one with a pendulum). It was eventually deemed not attractive enough to hang on the wall in many upscale homes, so wooden or glass and wooden cases were added. The long-case or grandfather clock evolved from this early wags-on-the-wall. Wooden cases were used to hide the unsightly weights and cast-iron pendulum.

The style did not disappear as many manufacturers continued making the wag-on-a-wall style clock to this day.

There were several clock assemblers operating in Canada up to the mid-1970s, and it was likely imported and assembled by the Forestville Clock Company of Toronto.

It is a rack and snail movement possibly made by Hermle. The second wheel teeth are larger than one would expect so, a lot of thought went into the design of this movement. I have worked on similar movements in the past though this one is a bit different, specifically the arrangement of the hammer assembly, one main wheel is the reverse of the other, and of course, it is a weight-driven time and strike clock.

Based on my initial observations the movement looks fairly clean despite the tarnished brass but I am expecting minor wear issues commensurate with a 60-year-old mechanical clock.

Disassembly

I took a number of photos prior to disassembly. This is my regular practice and although I have worked on many similar movements though there are always minor intricacies that differ from manufacturer to manufacturer.

To remove the movement from its case, two slotted screws holding the movement to the seat board are released plus, the weight chains must be pulled out. To release the chains the weight hooks must be removed.

The rack and snail assembly, minute wheel, hammer assembly, escapement, and pendulum leader were removed initially and placed in a collection tray. What remained were the wheels and the lifting lever between the plates secured by four pillar nuts.

The gathering pallet arbour and the main arbour are pressure fit. So, when I separated the plates most of the wheels fell out, of course. It can be a challenge for first-time clock repairers but when one works on a few there is a certain logic to the placement and orientation of the wheels.

Assessment of the movement

Because there was generally little wear, I made three decisions. I elected not to separate the central arbour and did not pull the gathering pallet from its arbour. As a result, the plate with two arbours attached was placed in the ultrasonic. I did not disassemble the main wheels which were held together with pressure washers. The main wheel ratchets and chain teeth are in very good condition and the ratchet assembly worked as it should and there was no need to take them apart.

I cleaned up residual oil and dirt around the pivot holes, removed excess oil from the pates, inspected the pivots for wear, and placed all parts in the ultrasonic cleaner. Since I was using a smaller machine than my regular US cleaner, the parts were cleaned in three batches which took a little longer.

I took special care drying the main wheels assemblies and ensured they were operating correctly after they were completely free of any moisture

My wife’s hair dryer came in handy but after cleaning and drying all the parts it fell off the table and broke. Sigh!

The pivots, which are in very good condition, are polished, the pivot holes pegged out and the next step is bushing work. Two bushings are required, the second wheel front plate and the centre wheel, back plate. There is minor wear on those two holes but why not address them while the movement is apart.

Reassembly

As with many rack and snail movements, most adjustments are made after the wheels are installed within the plates but three minor adjustments make the job easier and that is ensuring the gathering pallet is free of the rack, the stop wheel is in the 12 o’clock position and the hammer actuators are free of the star wheel. They must be between the star tips, if not, one of the hammers will catch on a star tip and stall the strike.

Testing

Once fully assembled the next step is installing the chains, weights, pendulum, and testing/adjustment. A small adjustment to the height of the pallets was made after which the clock ran well and continued to run well after 5 days. It is keeping very good time, as expected of a weight-driven movement as any clock that is powered by weights releases its power uniformly through its rated cycle.

Yes, it is a very plain-looking clock that reflects the style of the time (the 1960s) but it might grow on me.

Cleaning an antique/vintage clock movement – Ron’s method

Let’s clear something up right away: I am not a “Dunkin Swish” enthusiast. If you’ve been researching the clock-collecting world for a while, you might have come across this term. If you haven’t, consider yourself lucky—it’s something best avoided at all costs.

“Dunkin Swish” (apologies to those named Duncan) refers to the practice of placing an assembled movement into a cleaning solution or an ultrasonic cleaning machine, drying it off, and then declaring it “clean.” This is the absolute worst method for cleaning a clock movement and is never a good way to clean mainsprings within their spring barrels.

Why? Only by disassembling the movement can you properly inspect parts, polish pivots, peg holes, and thoroughly remove the dirt and grime that accumulate in the small crevices of a movement—buildup that will accelerate wear over time.

There is only one method to properly clean a clock movement, and complete disassembly, which includes removing mainsprings from their barrels/arbours.

Here are the steps I always follow when cleaning clock parts.

In most cases, clock parts can be safely cleaned using an ultrasonic cleaning machine. However, in rare instances, when working with something very old and delicate, hand cleaning may be the only viable option.

For the purposes of this article, I will assume that most clocks you work on are standard common-place brass mechanical movement types found worldwide.

Let’s get started.

Pre-cleaning

Once I have the movement disassembled, I clean any stubborn stains and wipe off excess oil from the parts beforehand. From experience, I’ve learned that while an ultrasonic cleaner works remarkably well, it’s not a magic solution—tough stains don’t always come off easily in the cleaner.

Pre-cleaning has an additional benefit: it extends the life of the cleaning solution. The solution can be reused multiple times, but once it becomes too dirty or cloudy to see through, I dispose of it. Proper disposal can be a challenge, which is why I always opt for a non-ammoniated, biodegradable solution.

I also clean all the pivot holes with peg wood or toothpicks and remove oil from the pivots beforehand. Additionally, I wipe away excess oil and dirt from the mainsprings.

The ultrasonic cleaner

In the early days of my clock repair work, I used an inexpensive ultrasonic cleaning machine. It was adequate for small jewelry items and acceptable for clock parts, but as I could afford something better, I decided to invest in a commercial-grade product.

I came across many Chinese-made ultrasonic cleaners on Amazon and eBay. While some may have had positive experiences with these machines, and the prices are certainly appealing, I was looking for something of higher quality and with a solid warranty. I have no issue with Chinese ultrasonic machines, but I would only consider them if they offered a reliable return policy and warranty.

I chose L&R for two main reasons: their reputation and warranty. I get no credit for mentioning this company, but the link will allow you to explore their product line to find the right size for your needs. After four years of continuous use, my L&R cleaning machine has performed flawlessly. L&R meets all of my requirements.

Ultrasonic cleaner by L&R — L&R Quantrex Q140, 3.2L with heater

The Q140 with heater is the size I opted for. It will hold one complete movement but is a tight fit for larger movements. Its smaller size means less cleaning solution is used and quicker heat-up times.

A high-quality ultrasonic cleaner will not disappoint. While there may be other brands that are equally good or even better, you generally get what you pay for.

Using an Ultrasonic Cleaner

Ultrasonic cleaners use cavitation, generated by ultrasonic waves, to clean objects made of non-absorbent materials. Ultrasonic cleaning effectively removes dirt, grease, and other contaminants from delicate components without causing damage. Just look at how bright and shiny this 30-hour movement looks after ultrasonic cleaning. That said, achieving an absolutely shiny movement is not the goal.

_{30-hour movement after cleaning in Ultrasonic}

Should everything go into the ultrasonic cleaner? Avoid mixing metals beyond brass and steel in the cleaner as they may react with each other. I also avoid placing anything plastic in it. Some modern clock movements with plastic or nylon gears and parts should be cleaned separately and not placed in the ultrasonic cleaner. Hammer heads made of leather should not be placed in an ultrasonic.

Use your own judgment with friction-fit parts, such as a center gear and pinion, as there is a risk of damaging them if you’re not confident they can be reassembled easily. Otherwise, disassemble as much of the movement as possible.

Choose the Right Cleaning Solution

Avoid using flammable substances such as alcohol, gasoline, or other volatile liquids. These can vaporize, potentially causing a fire or explosion, and release harmful gases into the workspace. Inhaling these toxic fumes is never safe.

Only solutions that are specifically designed for an ultrasonic cleaner should be used. Among acceptable cleaners is Polychem Deox 007 as a cleaning solution that works effectively. The mix is 5 to 1 ratio with water and it is free of odour. According to their product brochure Deox-007 is “an environmentally friendly, non-ammoniated concentrate cleaner. It is mildly alkaline for the efficient removal of oils, grease, tarnish, stains, corrosion, and oxidation from brass, bronze, copper, gold, and silver”. Once it has outlived its usefulness it can be safely dumped down the drain.

_{Wire basket holding an American-style movement in the ultrasonic before the} _{solution is added}

Many cleaners have a safe fill line, typically about 1 inch from the top of the tank. Whether you’re cleaning one part or several, always ensure the solution reaches this fill line.

A stainless steel wire basket is also necessary as it is not advisable to place parts directly on the bottom of the cleaning tank. A stainless steel wire basket is necessary because placing parts directly on the bottom of the cleaning tank can cause them to become damaged. The basket keeps the parts elevated, allowing the ultrasonic waves to clean them evenly without contact with the tank surface.

Although I always drain the solution after each use, I understand for the sake of convenience why some repairers leave it in the tank if the ultrasonic cleaner is used daily.

No cleaning method I’m aware of is as effective at cleaning lantern pinions as an ultrasonic cleaner. The results are truly remarkable.

The Ultrasonic Session

I pre-heat the solution which involves pouring in the solution, turning on the heater, and allowing the ultrasonic to come up to temperature. It takes about 10 minutes.

I typically run the ultrasonic for 20-30 minutes, which is usually sufficient for most jobs. On rare occasions, I’ve run parts through a second time.

Next is drying all the parts and this is where speed is essential. It is surprising how quickly rust forms on the steel parts. I use shop towels and for difficult locations such as lantern pinions, I use a hair dryer. Occasionally, if my wife is baking I will put the parts in the oven during its cool-down phase.

Years ago, some repairers salvaged parts from discarded hot-air popcorn machines, but I don’t see those around anymore. Additionally, in the past, some repairers designed heat boxes using a light bulb, but today’s LED bulbs run far too cool.

_{Sessions mainsprings are cleaned and ready to be re-installed in the movement}

If you choose to place mainsprings in the ultrasonic cleaner, it’s important to dry them as quickly as possible.

There are two reasons why you might prefer to clean them by hand. First, they can be easily cleaned on a spring winder, and second, the solution will become dirty very quickly, shortening its lifespan.

Olie Baker spring winder. Cleaning the strike side mainspring — _{Cleaning a mainspring}

One could clean in phases—first the time side, then the strike side—if drying is a concern. Ultimately, it’s up to personal preference.

Using a small metal lathe to buff the Wheels

To buff the wheels using a small metal lathe, securely mount the wheel on the lathe’s spindle and gently apply an emery board to the wheel. Run the lathe at a low speed, applying light pressure to achieve a smooth, shiny finish.

Next, clean the pivots with an emery board. To clean the pivots with an emery board, lightly hold the board against the pivot while moving the emery board up and down at a low speed. Use gentle, consistent pressure to remove any grime or oxidation without altering the pivot’s shape or surface. Use a soft cloth to wipe off any excess residue from the pivots.

Next Steps

Once everything is dry, the next phase involves any necessary bushing or pivot work, followed by reassembly and testing.

So, that’s the method I follow. If you have a different technique or additional steps that you include in your process, I’d love to hear about them.

Clock auctions – Ron’s rules for bidding

The psychology of auctions, now that would be a fascinating study. How bidders behave, the frenzy of bidding wars often called “auction fever“, and the emotions wrapped into the pursuit of that one item everybody seems to want would be very enlightening.

_{Ingraham 30 hour cottage clock, under $30 at auction}

Auctions are fantastic places to find great deals. I have found many clocks at auction for exceptional prices and have few regrets.

This post will explore how to use auction rules to the best advantage based on my experience and my observations. Presented are Ron’s tips that I have found effective. The focus is on online auction houses. eBay is another world but I suppose some of my advice may apply.

The photos on this page are auction wins over the past two years.

The classic auction

Although there are other types, the classic type of auction is where a seller sets the price, plus a time limit and bidders are encouraged to bid on the item. The highest bidder wins. This type of auction remains popular because of the familiarity and intuitive nature of the process.

Auctions can be live or online but online auctions are becoming much more common.

Using the “watch list” if offered

Many auction sites have a “watch list” which is a cool method of bookmarking the items you may (or may not) bid on. I generally peruse the auction offerings and click the watch button for those that interest me and in so doing generate a “list” of ten to twenty items for potential bids.

I hold off on bidding until I can determine which ones interest me the most, how much I am prepared to pay, and the total I have budgeted for the auction. I attempt to work within my budget but may make some adjustments during the auction.

The watch list also allows for a sober second thought before or during any auction. Put another way, I thought I wanted the item before but now I don’t.

Why you should not bid early

Auction sites want people to bid early to show everyone there is interest in the item. By revealing interest in the item others might be tempted to bid and this will drive up the bids. This benefits the auction house which makes more money on any item that sells higher. Novice auction goers are easily caught in this trap. Try not to get caught up bidding too high and too early in an auction even if it is something you really want. Fight the urge!

Establishing a limit

I consider each item carefully based on the photos and descriptions provided, determine what I would pay for the item in optimal condition, and factor in wear and tear or any parts missing in order to set an upper limit for my bid.

A tactic that works surprisingly well is to determine a maximum price on an item when the auction opens, make that bid and leave the auction.

_{Scottish tall case clock, $275 plus fees and taxes}

Let’s say I bid $60, then leave the auction site. The next day or after the auction has ended, I will know if I won within my limit, or lost. If monitoring the auction a green win button will light on what you have won otherwise auction houses send out invoices after the auction has ended detailing items you have won. Winning is very satisfying, of course, but losing is not such a terrible thing, there is plenty of fish in the sea.

Others participating in the auction might also have set the same limit for themselves on a particular item. If I’m willing to spend $60, am I willing to spend $5 more (assuming a bid increment is $5). If I bid just higher than my limit assuming my limit is the same as others, I may still win the item without ignoring the budget I have set for the auction.

Without determining your limit, it’s too easy to get into a bidding war that might go something like this, “I was willing to spend $75, and I was outbid at $80. I could go $5 more and bid $85 but if I lose it at $85, $10 is only a tiny bit more”, and so on.

Stay within the upper limit and do not get caught up in a last-second feeding frenzy.

Auction “estimates”

This is just another method of forcing the bid higher. Ignore auction estimates unless there is a “reserve” on the item. A reserve price is a minimum price that a seller would be willing to accept from a buyer. In an auction, the seller is not typically required to disclose the reserve price to potential buyers. If the reserve price is not met, the seller is not required to sell the item, even to the highest bidder.

Proxy bidding

Most auction sites allow proxy bidding, meaning they will keep your bid as low as possible so you can win, but not exceed your maximum limit.

It works this way. I decide on a $60 upper limit and the auction’s bid increments are $5. At the start someone bids $5, I have set my bid at $60 but currently have the winning bid at $10. If someone else bids $25, my bid automatically goes to $30. They come back at $35, and my bid automatically goes to $40. If the auction ends at that point, I won the item for $40. If someone else came back before the auction ended with a $65 bid, then they win, but I do not exceed my limit. I then walk away from that item and focus on the next.

Rare items

Rare items that are desirable can be expensive. Humans tend to overvalue things they think are rare. However, thinking an item is rare might influence you to bid higher. The item may, in fact, be quite common. Do your research beforehand, or even during the auction.

For example, ogee-style clocks that some people would consider to be quite rare are, in fact, very common as thousands were produced by many American manufacturers over a span of 70 odd years.

_{Chauncey Jerome ogee clock, $35 at auction}

Not so hidden fees and costs

There are additional fees and taxes as you would expect. Auction fees called “buyer’s Premium” is set by the auction house. The buyer’s premium is a percentage that is an additional charge on the hammer piece of the lot which is paid by the winner. Some auction houses will call it a service fee but think of it as a commission.

Buyers’ premiums may be higher for online auctions than live auctions and the percentage varies from auction house to auction house, typically between 15% and 20%. Some auction houses may even have an additional service fee above the buyer’s premium. Add taxes to determine the final price. A winning bid of $60 with a 15% buyer’s premium (our local auction houses) and sales taxes of 15% (Nova Scotia) pushes the final price to $79.35. It is the final price assuming you can jump into your car and bring the item home, otherwise, there are shipping costs. Suddenly your $60 win costs $200.

As a general rule, I do not request antique clocks to be shipped as the risk of breakage is too high.

The psychology of ownership

Here’s how it works. While you hold the winning bid, you begin to feel a sense of ownership, and the longer one holds the bid the stronger the sense of ownership. When outbid, you may think someone is trying to steal something from you and you want it back but now you are caught up in bid frenzy. To get it back you bid higher. However, even if you win the item you still lose because you have likely overpaid for it. Buyer’s remorse is the sense of regret after having paid too much.

Related is the Endowment Effect, meaning people will assign more value to an item that they own purely because they own it. This type of behaviour is typically triggered with items that have a strong emotional or symbolic significance to the individual such as something they had as a child or other nostalgic item.

A pocketful of money

Let’s say I plan on spending $500 at an online auction including buyer’s premium, tax, and shipping, so, I am limiting my actual bidding to approximately $300. Perhaps I am looking at only two items in the auction. For one I’m willing to go to $100, and for the other, I’m willing to bid up to $200 for a total of $300. I win the first item (for which I was willing to spend $100) for $25. I can now decide whether I should spend $200 on the second item, or if I’m now willing to go up to $275.

Determining a budget limit introduces an element of self-control and allows one to refocus attention on other auction offerings. It is also helpful when you are not watching the auction when it ends.

This is always an individual choice based on how much you feel the items are worth and what your research is telling you.

_{Ansonia Canada parlour clock},_{part of a $30 lot}

Clock auction houses

An auction that consists only of antique clocks is a tough one to navigate and to win an item at a decent price. These auctions attract all manner of collectors and you might be bidding against a very determined collector who will want an item at any cost.

I find the prices in antique clock auctions to be generally quite high and unless you are looking for that special clock it is best to avoid them unless money is no object. I have much better success with estate auctions that do not generally attract dedicated clock collectors so, for the most part, you are bidding against people who have poor knowledge of antique and vintage clocks.

I suppose there are plenty of other strategies but these are the ones that have worked for me.

Refreshing an Ingraham “octagon top” 30-hour shelf clock – keep or sell?

This 30-hour shelf clock (hour strike) was manufactured by American clock-maker E. Ingraham and Co. in the 1870s. There are various iterations of the name over the maker’s history but this was the one the company used from 1861 to 1880.

The clock was bought at auction in mid-March 2022 along with 3 other clocks. In this post, I will take the reader through the process of refreshing the case.

This is an excellent example of a tired case that needs attention. When I look at a clock case such as this I assume the movement is well worn but a pleasant surprise awaited.

The movement is in surprisingly good condition as a result of regular (somewhat) servicing over the years. It has been in the shop at least three times, 1879, 1916, and 1994 according to dates found on the back of the case and perhaps more occasions that are not recorded.

Analysis of the case and plan of action

The gold banding on the front face of the “octagon top” and the inside frame of the access door has some losses and the goal is to hide the nicks with gold artist’s paint matched to the trim. First of all, it is not a true octagon but half of one, but that is how these clocks are described.

The overall finish is in fair condition. Numerous cosmetic issues such as scratches and nicks here and there over the rosewood case are evident, but a good cleaning with soap and water followed by a fresh coat of shellac should fill in the scratches and improve things dramatically.

_{Auction photo showing nicks and scratches}

The dial shows considerable wear after years of daily use and this is a situation where a replacement paper dial might be considered but I am always hesitant because replacement dials take a certain something away from and antique clock.

However, I am going to see what I can do by attempting to bring the numbers back with black acrylic paint while retaining some of the patina.

The moon hands look correct for the period of the clock.

As a collector who has seen a good number of these styles of clocks, I first thought the access door glass was a replacement since many clocks from the early to late 19th century had reverse painted tablets.

Because of the decorative pendulum and the bright brass bell both meant to be seen, the stylized panel that serves as the base for the dial, the total absence of any paint remnants, the glass panel with its waviness and various imperfections plus the putty-like material that is used to mount the glass to the door, the glass appears to be original to the case. A pleasant surprise!

It is always a bit of a disappointment when something is lost or changed on an antique clock especially one that is close to 150 years old and when replacement parts are difficult to source.

No doubt some of the scratches on the case, dents, etc. (not all, of course) are the result of rough handling either when transporting the item to the auction house or during its stay.

Addressing issues with the case

The very first step is a good cleaning. Cleaning a clock will generally result in the removal of some of its protective finish but it is inevitable given that it has been on the clock a long time.

For old American clocks I generally use traditional shellac made by combining shellac lacquer with shellac flakes. Amber Shellac adds a certain hue to the case and the cut is light enough that it dries to the touch in less than a minute which is my preference.

When there are large flat surfaces I will use a “french polish” but for this project, a broad artist’s brush is best. I apply the shellac in long strokes completing each section at a time.

The decorative black wood panel that serves as the dial mount is also shellacked allowing for small scratches to fill in very nicely.

The original paper dial is well worn and presents significant challenges as all the numbers on the dial are either partially worn off or completely erased. This was a well-used clock!

_{Top and bottom lines of the numerals are filled in}

Using an artist’s fine-tipped brush, black multi-surface acrylic paint, and a steady hand I filled in as much as I could. The numbers around the winding arbours were the worst because I had little to work with and they were the most difficult to reproduce.

Once all the Roman numerals were completed and thoroughly dry, I used a Sharpie fine-tip “artist’s permanent marker” and a straight edge to clean up the lines. I decided not to touch up the chapter ring other than the 5-minute markers. I am not entirely happy with the number 4 on the dial but that’s as far I am going.

As for the gold trim on the face, I did not want to mess with the patina, nor did I wish to cover the gold which would have completely taken away from the antique look. I mixed acrylic multi-surface gold paint and a very small dab of black paint for an “aged” effect and used a fine-tipped artist’s brush to carefully dab the bare areas.

Finally, the brass bezel and inner ring were given a polishing.

The clock has been transformed. The dial has been rejuvenated, the movement serviced and reinstalled, the bell gong attached, the case given its many touch-ups, and the decorative pendulum is attached. Now to regulate the clock.

In the final analysis, I believe that I have struck the balance every collector and restorer seeks and that is maintaining the original patina of the clock while not taking away its antique look. It is 145 year old antique that has seen good use over the years but applying modern techniques that are minimally invasive have brought it back to life.

I have one more decision to make. I acquired this and three other clocks to sell in order to offset the cost of new equipment but now that I have seen the final result I wonder!

Tick Talk Tuesday #41 – who made this clock?

_{Tick-Talk Tuesday is about the letters and comments I have received from readers concerning clock issues, challenges faced, a clock you would profiled or advice on your particular clock concern.

PN writes:

We bought this wall clock about 30 years ago at an auction. We would like to sell it. Can you tell me anything about it and/or it’s value? I appreciate your time.

My reply:

How is the movement mounted in the clock? Is it mounted to rails (so that it can be removed easily by loosening 2 thumb screws) or by screws on the backboard. If it is mounted by screws to the backboard it is not German, French or British. It could be American but I doubt it.

I do not believe your clock is an antique. The ornate carved design is very much a feature of Oriental clocks and possibly Korean from about the 1960s or 1970s. There were some nicely carved antique American clocks but nothing this extensive. I have not seen one exactly like it but ones that are very similar.

These clocks show well and are sought after by some people looking for a unique decorative item but as to value, perhaps two or three hundred dollars or so.

Schatz and Sohne carriage clock – a second look

Schatz and Sohne, the maker of this pretty little 8-day carriage clock may not have considered that one day their carriage clocks would require servicing. Did they make a throw-away clock? We’ll see.

Many were sold and typically gifted to family, friends, and business associates. Over the years they have either been tossed out, found their way to antique shops/flea markets, sold to people like me or sat on a shelf never to run again. Yet, they are nice looking clocks.

Does the beginning of this blog sound familiar? If you are a regular reader you will note that I wrote about this clock a few weeks ago. Not happy the first time, I decided to tackle the movement a second time hoping for a better result. My approach is to give every movement my best effort and up to this point I have lost very few patients so, I was not going to allow this one to get the best of me.

My initial efforts to fix the clock produced a result that was no better than when I got it. It ran about 4 days and after servicing I was unable to improve on the running time.

Was it worn? Everything looked very good except for the second wheel (middle plate) bushing hole which was very badly worn, not surprising since the second wheel accepts the full force of the main wheel.

_{The worst bushing wear I have seen in a while}

The thin brass plates don’t help since they exacerbate wear. A new bushing was installed and it was a good fit, worked perfectly but was very close to the edge of the plate.

_{As good as it gets but very close to the edge of the plate}

During the first run-through, I thought I had nailed it. It should have run for 8 days. It did not.

_{Escape wheel at the bottom of the movement}

However, in that first servicing, I did not clean the mainspring.

This time the mainspring came out of the barrel. It was not an easy task to extract it as the barrel is very small, 35mm in diameter, and too tiny for my Olie Baker spring winder (why I did not tackle it in the first place). Compare the barrel size to the winding key in the next photo.

Once the barrel cap was off, and the winding arbour removed I snagged the mainspring in the centre with a pair of needle-nosed pliers and pulled it from the barrel. Gloves are necessary as you never know how much force a mainspring will have once released from any barrel.

It was dirty but was that enough to affect the running of the clock? Will servicing the mainspring improve things? Hmm!

While the mainspring was out of its barrel I gave it a good cleaning followed by a wipe-down with Keystone mainspring oil. Back in it goes. Easy enough to take out but very frustrating to put back into the barrel. A few curse words and some encouragement and the spring found its way into the barrel.

It will be tested without the case and dial attached. So far it looks good but it has run for only a few hours.

Will it run for 8 days?

2 weeks days later

Servicing the mainsprings might have given me the 8 days I was seeking but that might not have been possible without fine-tuning the hairspring escapement which I believe contributed equally to a better run time. An adjusting screw on the escape wheel allows for fine-tuning but I had to rely on trial and error to find the sweet spot. Success in the end.

My intention was never to make this clock a daily runner but it is nice to have something that runs according to its original design. My cost was one bushing and, of course, my time.

It will be displayed, and run occasionally. Oh, and about that mainspring; I cannot imagine anyone with arthritic hands trying to wind it once per week, that mainspring is so powerful.

These are very cute little carriage clocks and they can be successfully repaired but I would certainly not put a great deal of money into servicing one unless, of course, it has deep sentimental value.

I was wondering if you could take a look a this clock for me. It belonged to my great grandmothers mothers. My great grandma recently passed at 108. I can only imagine the age and value of this clock. I know it’s called Mauthe.

My reply:

Hi and thanks for your email.

The clock looks to be in fair condition although I would remove the cement/putty(??) on the door frame. These clocks do not have a lot of value, probably the $100-150 range. It looks to be from the 1920s, or 1930s. Some were quite large and ornate with intricate wood carvings but your appears to be at the lower end of a model range.

They are known as box clocks because of their style. Mauthe and other makers made literally thousands of them and they sold very well but the company eventually went out of business in 1976.

The movements are quite robust and they will last for years and are easily repairable unless there are serious problems as parts for them cannot be sourced.

If it has sentimental value I would keep it, have it cleaned and serviced and displayed in a prominent location. Most Mauthe clocks have wonderful sounding strike gongs but are not loud tickers.

Hope this helps.

Are inexpensive carriage clocks worth fixing? Schatz and Sohne

Schatz and Sohne, the maker of this attractive 8-day carriage clock may not have considered the fact one day their carriage clocks would require servicing. Did they make a throw-away clock? We’ll see.

Many were sold and gifted to family, friends, and business associates. Over the years they have either been tossed out, found their way to antique shops/flea markets, or sat on a shelf never to run again. They are pretty, however!

Were they meant to be repaired and are they fixable? Perhaps.

Just about any clock can be fixed. However, the cost of a professional service would be far more than it is worth but may be justified for sentimental reasons. In the case of this clock a professional service would be out of the question.

I paid $40 for this clock. The seller said that it runs for 4 days and stops. He was quite correct. I wound it fully each time and over the course of a few weeks, it promptly stopped at about the 4-day point. I appreciate the seller’s honesty.

The loss of power that is consistent in this clock’s cycle tells me that there is serious wear at some point in the train. Some might immediately assume that the mainspring is weak but in my experience mainsprings are generally much more powerful than required.

So, let’s see what we have.

Disassembly

A rubber band or two comes in quite handy when employed to hold the four glass sections in place while taking the clock apart. Next, unscrew the key and pull out the small knob used to change the time. Four screws hold the base to the glass sides and top of the clock.

Carriage clocks such as this example are more decorative than functional but are they worth fixing?

The first step in removal is to pull out the works from the base, then, pull off the hour and minute hands which are both friction fit. Next, the dial face and front section are removed by means of two screws that hold it in place. The base is removed from the movement, again, two screws hold it in place.

_{The movement showing the escape wheel}

Once the movement is removed it becomes apparent that three plates are required for the gear train. The design is not far removed from a conventional time-only clock except for the upside-down configuration with an inverted escapement. The third plate is effectively used as mounting points for the dial, the mainspring barrel, and the escape wheel arbour.

S_{ide view of the movement showing the three plates}

Six screws hold the plates together. Once the rear plate is removed, the wheels are revealed.

The wheels are very small and the pivots are tiny and easily bent. Though I was careful, I can imagine anyone using brute force to bring the plates together upon re-assembly could easily risk bending or breaking a pivot. Therefore, extra caution is highly recommended.

As for wear, everything looked very good except for the second wheel bushing hole which was badly worn, not surprising since the second wheel accepts the full force of the main wheel. Thin brass plates also exacerbate wear.

I believe I “might” have found the cause of the power issue. The bushing hole shown below is elongated enough to cause problems transmitting power up the train.

That one was the worst by a large margin. All the other pivot holes had acceptable wear and did not require new bushings.

All parts were cleaned in the ultrasonic, the pivots were polished and pivot holes pegged out.

Now for bushing work

I have installed hundreds of bushings on clocks and this one was a real challenge. The pivot on the second wheel is 1.27 mm. The Bergeon bushing I chose has a 2mm diameter. Anything larger would have required removing too much brass making the new bushing potentially loose and unstable. As it stands there is a slight bulging of the brass plate where the bushing is installed.

Because the inside diameter of the bushing was .95mm a considerable amount of broaching out was required to enable it to fit the 1.27mm pivot. The result is a thin sidewall but sufficient to do the job. Using a pivot cutter I reduced the height of the bushing for a nice clean fit.

Just one bushing but a tough one.

Reassembly

Reassembly went without issue though I had to refer to the photos I took during disassembly to determine when all those darned washers had to go. Photographing each step in the process always pays dividends in the long run.

A pivot locator comes in very handy when putting it all together. Using the locator, the pivots are gently convinced to find their respective holes.

Once the escape wheel hairspring peg is pushed back into its post it is time to give the escape wheel a little spin and test the movement prior to returning it to its case.

And the final results

After disassembly, cleaning, addressing a serious wear issue, and testing, the final result is…….yep, it runs 4 days and stops.

I may remove the mainspring from its barrel (not something I did this time) and give it a good cleaning but I think that is it.

Will I go further and perhaps replace a weak mainspring? No! I am not going to put more money into a clock which, at the end of the day, is nothing more than a decoration. It is just not worth it.

Pretty to look at though!

Should mainsprings be routinely replaced on an antique clock when servicing?

A mainspring’s purpose is to provide motive power for the wheels to move in a clock train. All mechanical clocks require a power source and the power source may be by weight or spring. Mechanical clocks that have mainsprings will have one, two, or three winding points which, once wound provide power for a clock’s designed cycle.

Each winding point or arbour is located on the dial face and requires a key (one key fits all arbours) to wind the clock. The mainspring is rated to provide power for a clock’s designed cycle, whether it be 1-day, 8-days, 15-days, and so on.

_{Sessions mainsprings cleaned and ready to be re-installed in the movement}

Mechanical clocks are machines and over time machines wear out. When a clock will not wind up, it is time for a service. The service can be done if you have the skills and equipment otherwise you must depend on a professional clock repairer.

Should mainsprings be replaced during routine servicing?

Though not in the clock repair business I am aware that some repairers routinely replace mainsprings and, of course, the cost is passed on to the customer. Should they be replaced on a routinely or only when necessary?

As a general rule, I do not replace mainsprings when servicing a mechanical clock unless there is something fundamentally wrong with the spring(s). Obviously, there are situations where a mainspring must be replaced when it has failed in some catastrophic manner.

Broken mainspring for barrel — _{Broken mainspring which is not saveable}

There may be occasions when there is too much surface rust or stress cracks on the mainsprings which will make them susceptible to failure and/or seizing and the prudent course of action is to replace them.

_{Ansonia time-only movement –} _{Too rusted to save?}

However, repairers reason that new mainspring(s) will extend the period between servicing and provide additional insurance for the repairer so that if the clock stops soon after servicing, issues other than the mainsprings are suspect.

New quality mainsprings (American or German) also provide more power than the springs they replace and more power means they will continue to provide sufficient power for the clock through its rated cycle even if very worn.

Installing or punching a bushing — _{Addressing wear by punching in a new bushing}

The original mainsprings are often of better quality than a new spring. They may not have as much power as a new mainspring but many clocks, despite the fact that they are over 100 years old have springs that have more than sufficient power.

Once the movement is thoroughly cleaned, the pivots are polished and pivot wear is addressed there is less friction on the moving parts and therefore less power is required to drive the movement through it rated cycle.

What if there are minor issues with the mainspring?

There are certain situations where a broken mainspring may be salvaged if the break is at the hook or loop end but not if it is broken in the middle. The mainspring can be shortened by two or three inches and after the repair, the spring will continue to provide sufficient power for the clock to run through its cycle.

What to do if your clock requires servicing by a professional

Should you bring your clock in to be professionally serviced ask plenty of questions. If it is recommended that the mainsprings be replaced, ask why, specifically. Once you receive a satisfactory explanation proceed with the repair.

New mainsprings, when the cost is upwards of $25 for each mainspring, will add substantially to the repair cost, something to be considered if the clock has little value. Of course, if it is to be repaired for sentimental reasons the cost is immaterial.

Mainsprings need not be replaced simply because they are old and “tired” and it does not require a lot of power to run a mechanical clock if serviced correctly.

Your choice!

Dating a Hamburg Amerikanische Uhrenfabrik (HAU) shelf clock

During the Christmas season, we split our time between Calgary, Alberta, and Ottawa, Ontario to see our 2 daughters. While in Calgary my wife spotted an interesting item on an Ottawa Facebook Marketplace, an English time and strike clock.

She showed me the photo and I said, “that does not look like any English clock I am familiar with. The style is definitely German”. There is a commemorative plaque on the front base section which references an English church so, I am assuming the seller thought it was English.

When we picked it up from his home outside Ottawa I was surprised to learn that the seller is a clock collector and had no idea the clock he was selling was German. Occasionally I sell clocks to manage my collection and when advertising one for sale I make it a point to know the maker.

But, no matter, it was in very good condition and in working order.

_{The movement showing the single strike rod and pendulum bob}

The maker is HAU or HAC. The familiar cross arrows trademark of the maker is stamped on the movement, in the middle of the backplate.

HAC was formed in Germany in 1873 by Paul Landenberger and Phillipp Lang and was originally called Landenberger & Lang Uhrenfabrik. The company changed its name to Hamburg Amerikanische Uhrenfabrik (HAU)/Hamburg American Clock Company (HAC) in 1883. The famous crossed-arrows

became their trademark in 1892. In 1926 the company went into a cooperative with Junghans and in 1930 they finally merged with Junghans.

The date on the plaque says 1926. However, HAC/HAU clocks are difficult to date prior to Junghans acquisition of HAC/HAU in 1930. Once Junghans and HAC began their collaboration in 1926 some of the movements were date coded.

Plaques are a good but not foolproof method of dating a clock. A clock purchased as a gift in 1926 could very well have been sitting on the retailer’s shelf for two or more years.

Catalogs are another good but hardly foolproof method of dating a clock. A catalog confirms that a model was made in a particular year, but that same model was probably offered 5 years +/- from the year of the catalog.

I will probably not determine a more reliable date for my new clock than circa 1926. The movement, compared to an earlier model (below), also has many cutouts and additional holes that indicate that it was a late production model and confirms that is closer to the 1926 date.

_{Solid plates of an early HAC clock movement CA. 1895}

The clock runs for a while and stops. It is in need of a service but I expected to clean it as many of these old clocks have rarely seen the inside of a clockmakers’ shop.

Maritime Association of Watch and Clock Collectors

On November 2-3, 2019 the Maritime Association of Watch and Clock Collectors held its first meeting. Members came together from various parts of the Maritimes to meet in Prince Edward Island (Canada) to form a club of like-minded individuals.

A educational component of the meeting, a lesson in bushing

Unfortunately the pandemic scuttled all plans for a subsequent meeting but the climate is right for another face-to-face meeting shortly. In the meantime the group has stayed connected through email.

The goal of this group is to gather individuals of every skill level from across the Maritime provinces (PEI, New Brunswick and Nova Scotia) to share experiences, mentor each other, learn new techniques, provide opportunities to acquire clocks/watches and foster social interaction.

We chose the name MAWCC, the Maritime Association of Watch and Clock collectors. We agreed to no less than 2 meetings per year but that sub-groups would meet more frequently.

At this point in time we are not affiliated with the NAWCC (National Association of Watch and Clock Collectors) an American-based clock and watch group.

Demonstration of the cleaning of a mainspring

If you are from the Maritime region of Canada (Prince Edward Island, New Brunswick, Nova Scotia) and you have a keen interest in advancing your skills in horology or just beginning your journey into clock and watch repair and would like to connect with like-minded individuals, contact Wendell Feener at wcfeener@eastlink.ca

Kienzle time and strike movement servicing

I have just one other Kienzle clock in my collection and it is a rather unusual one, the World Time desk clock from the 1940s. I do not come across Kienzle clocks very often. They are no lessor quality than most German clocks, I just don’t see many around this region.

The latest is a German styled round top box clock. It was a an auction buy. I knew it was German at the time but did not know the maker. After a little research I discovered that it is made by Kienzle Uhren.

Kienzle Uhren GmbH is a well-respected German clock company that has a long history.

The company was founded in Schwenningen in southern Germany, in the Black Forest, by Johannes Schlenker, in 1822. In 1883, Jakob Kienzle became part of the family by marriage, and took control of the company, becoming its sole owner in 1897.

Jacob revolutionized production by mass-producing individual components and then assembling them. This modern manufacturing approach led to a massive expansion, and by 1939, Kienzle had over 3,500 employees and was making about 5 million wall-clocks and table clocks per year.

The company continued on through the years, changing hands a few times and gradually shifted production to wristwatches. It continues in business to this day as a watch maker.

The movement

In many respects it is a typical well-engineered German movement from the 1930s. The movement is compact in design and anyone who has worked on German movements will feel right at home. It has a 43 cm pendulum length and runs at 104 beats per minute as per the stamping on the back plate.

Front plate showing rack and snail mechanism

Unfortunately, the spring barrels cannot be removed separately, the movement must be completely taken apart to replace the mainsprings if they break.

The 4 hammer strike assembly can be taken apart separately. One advantage is that once the plates are back together the strike paddle can be easily positioned on the star wheel. The strike has a repeater function which is handy.

With top plate off and showing the placement of the wheels

All parts are hand-cleaned before putting them in the ultrasonic cleaner. Taking excess oil and grime off the movement prior to cleaning ensures a longer life for the cleaning solution. When the solution gets dirty enough I discard it.

The movement has a combination of leaf and lantern pinions, leaf pinions on the second wheels and lantern pinions up both trains. I expect the ultrasonic will do a great job cleaning the lantern pinions.

Taking the mainsprings out of their barrels

The mainsprings must be taken out to be cleaned and the barrels cleaned in the ultrasonic. The springs are quite powerful and mainspring troubles account for many problems with German clocks.

When the mainspring breaks movement damage can result. Teeth are torn form the barrel and the first leaf/lantern pinion is destroyed or the second arbor is bent. I have had movements go both ways from severe damage to simply a broken mainspring (which is easily replaced).

Cleaning of springs and barrels is therefore essential not only to ensure they are free from old oil and dirt but to inspect them for cracks, breaks, and tears. These mainsprings appear to be in very good condition.

I typically preheat the Polychem Deox 007 solution and run parts for 20 to 30 minutes in the ultrasonic, switching off the heat midway through the cycle. I dry all the parts by hand and for the lantern pinions and some parts that seem to hide water, I use a hairdryer to ensure that everything is free of any potential rust build-up.

The mainsprings, which are cleaned of old oil are done separately in the ultrasonic cleaner.

All parts except mainsprings are placed in the ultrasonic cleaner

The next step is putting the re-oiled mainsprings back into their barrels and for that a spring winder is a must. Polishing the pivots come after that.

Bushing work

This movement might have been cleaned at one point in its life based on pivot scratches on the inside of the plates and worn screws on the back cock but it has never been bushed. When I tested the wheels in the movement I found the time side ran relatively freely while the strike side seemed stiff and sluggish. So, the movement is worn but the wear would be no more than typical for its age.

Following my first assessment I have determined that the movement requires as many as 10 bushings, 6 on the backplate and 4 on the front or, 5 on the strike side, and 5 on the time side. As expected there is more wear lower in the trains.

On the front plate are:

The second wheel time side, third and fourth wheel on the time side and the verge.

On the rear plate are:

Second wheel on the time side, second and third wheel on the strike side, third and fourth wheel on the strike side and the verge.

I always like to start with the most difficult, the pivot hole on the back cock which supports the suspension spring, crutch and pendulum.

In total 12 bushings were required, including the escape wheel. The escape wheel was pretty sloppy both front and back, and better to do those while the movement is apart. 12 is probably the most I have installed in a German clock in quite a long time.

Reassembly and testing

I generally perform a power test prior to the final assembly of the verge, rack and snail, and all outside pieces. It is a good check against my bushing work and if anything is tight or stiff I can address it without taking everything apart. Everything looked good at that point.

Both trains are moving and being tested before the other parts go on

However, with verge installed, pendulum leader, crutch and pendulum, the movement consistently stopped after a few minutes. I took it apart and discovered that the 4th wheel on the time side was moving stiffly. As that wheel had a new bushing installed all it took was reaming out the pivot hole to free it up. Now the movement is running well.

Testing the Kienzle movement on a makeshift test stand, beat amplifier is attached

Onward to the strike side and attaching the levers, snail and rack. The levers, rack and snail and gears are attached and finally the strike hammers are installed. The strike hammer posts must be bolted in from the inside of the back plate, something to remember when reassembling the movement.

When I got the clock only one strike hammer functioned but with all hammers repositioned all 4 strike hammers are doing their job and producing a melodic bim-bam strike.

The case does not require much attention other than a cleaning with soap and water.

There is absolutely nothing on the movement, gong block or case that tells me who the maker is though I now know it is definitely a Kienzle.

Tips on selling (or buying) an antique or vintage clock

If you are a collector or simply have a general interest in mechanical clocks and wish to sell antique and/or vintage clocks then, read on. I am not a seller but I purchase clocks to build my collection.

I occasionally sell clocks locally as a way to manage my collection. Most of the clocks I’ve sold have been serviced by me, and my main goal is to recover the time spent on cleaning and repairs, rather than promoting sales on my blog.

The Difference between Antique and Vintage

Let’s begin with definitions. Antique is anything over 100 years old and vintage is less than 100 years but more than 30 years old. Anything that is less than 30 years old may be considered vintage but more often it is called collectible. Try to pass off a 30-year-old clock as an antique and you will turn off a lot of prospective buyers.

Clock Terms

When selling a mantel clock, it’s important to use ‘mantel,’ not ‘mantle.’ A mantel refers to a shelf or structure, while a mantle is something one wears. Using the correct terminology also signals that you have a deeper knowledge of clocks than the average person.

A clock with two winding points (with some exceptions) is typically referred to as a striking clock, which strikes but does not ‘chime.’ A chiming clock usually plays a quarter-hour melody, such as Westminster or Whittington, and often has three winding points (though there are exceptions). There is no such thing as a ‘Tempus Fugit’ clock; ‘Tempus Fugit’ simply means ‘time flies in Latin.

A grandfather clock is a clock that stands 6 feet or taller and is not a wall clock. A grandmother clock is a floor clock that measures less than 6 feet in height. Grandfather clocks are also known as tall-case clocks, longcase clocks, or hall clocks.

Gingerbread and parlour clocks are distinct in design, but both are typically classified as kitchen clocks.

There are many other styles but let’s leave it at that.

Honesty and Disclosure

In my view, the most important element in selling a clock is honesty.

Inform the prospective buyer by describing as much detail as possible about the clock without getting too wordy. A clock that is a marriage, a case with a similar but replacement movement, should be stated as such. Replacement glass, newer dial, replacement crowns and finials, case repairs, or full case restoration should also be disclosed, perhaps not immediately in your ad but as a follow-up.

If the clock is running and was recently serviced by a competent repair person, state such in your ad. If the clock is running but the movement requires cleaning it should be stated as such. If it is not running explain why and what issues it might have such as a broken mainspring, missing pendulum bob, missing winding key, and so on. If you don’t know why it is not running, say so but be honest about it.

If you’re selling a clock and don’t know much about it, be honest and say so. Similarly, if you’re selling clocks in general but lack knowledge about them, it’s better to be transparent about that as well.

If your clock is rare, indicate why it is rare and support your claim with credible documentation including its provenance.

_{E. Ingraham shelf clock C.1878, not rare but uncommon}

Establishing a Value

Research auction prices to get a feel for the value of similar clocks that are offered for sale and the price realized. Sources are Kijiji, Facebook Marketplace, eBay, and any number of respectable auction houses.

There will be a range of prices and something in the middle of the range is a good guide though its condition will determine what people expect to pay.

Determining the condition of a clock is an important factor in evaluating its value. The clock’s overall appearance, functionality, and any repairs or restorations it has undergone will all impact its worth. A clock in poor condition generally has a lower value than one in excellent condition, as potential buyers may factor in the cost and effort required to restore it.

Know that a clock is only worth as much as someone will pay. If you price your clock too high you will know it soon enough.

Rare and desirable clocks, as well as clocks with an interesting provenance, will command higher prices.

Clocks also vary in price according to the geographic location where they are sold. Generally, clocks that are made in the same location as the clock is sold will command higher prices. English and German bracket clocks are not as popular in America as they are in Europe and are priced accordingly.

Preparations for Sale

A clock in running condition will fetch a higher price than one that is not. A professionally serviced clock in excellent running order will command an even higher price. A clock case cleaned of grime will present better than a dirty one. Missing hands or dial glass will adversely affect the price. Items such as these can be replaced and parts are available from clock suppliers but it becomes an extra cost for the buyer and for many, it is a deal-breaker.

If you are handy at clock repair, servicing the movement or any case repairs will enhance the value of the clock you are selling. If you have serviced a clock, always be clear about the work you’ve done. Describe in detail the specific repairs, cleaning, or adjustments you’ve made to the movement, as well as any parts that were replaced or restored.

This transparency not only helps potential buyers understand the value of the clock but also assures them that the clock is in good working condition. Whether it’s oiling, replacing worn parts, or correcting any mechanical issues, providing this information builds trust and demonstrates your expertise.

The term servicing has many definitions. Be wary as sellers may claim a clock has been serviced if the only thing done to it is oiling. Among reputable clock repairers, servicing is defined as, taking the movement out of its case, disassembling the movement, cleaning the parts, addressing wear issues/repairs/parts replacement, reassembly, oiling, and testing before reinstalling it back into the case.

Visual Presentation

While few cell phones (though some are improving) can capture highly detailed images of a clock, they often suffice for many purposes. However, blurry or out-of-focus photos are unacceptable.

_{Smiths Enfield mantel clock serviced and ready for its new owner}

Several images from different angles as well as a photo of the inside of the clock case are much more helpful than one photo. During the daylight, place the clock near a window and position yourself between the window and the clock to take a series of photos in natural light. If there is damage or wear take close-up photos of those areas.

In general, a dedicated camera with artificial light will produce better results than a cell phone camera.

Clock Description

Crafting an ad is an art in itself. You must be concise and accurate and not overly wordy. There is a balance between too little and too much information. Less information means fewer inquiries from prospective buyers. Too much information with technical terms will turn off prospective buyers. Try to anticipate the questions prospective buyers might have in order to limit the number of follow-up queries.

State the clock’s maker if known, the model if possible, the year it was made, the type, (time-only, time and strike, chiming clock), the style of clock (mantel, wall, shelf, parlour, Ogee, tall-case, etc.). as well as any interesting features, for example, a steeple clock with an alarm function or a clock with a second’s hand. Along with your description state the approximate age. If you do not know, a picture of the maker’s mark on the dial or the movement will assist prospective buyers.

While it’s not necessary to give a reason for selling, doing so can sometimes enhance the ad.

Where to Advertize

There are a number of ways to sell a clock. Facebook Marketplace is very popular. Other local online for-sale sites, eBay, flea markets, consignment shops, and auction houses are popular places to sell a clock. Setting up an account for most online sites is a pre-requisite but there is usually no cost.

Runs well and keeps good time, original key supplied. $250

Final Remarks

While selling a clock can be a frustrating experience, it can also be quite satisfying. I choose to sell locally to avoid shipping costs and the risk of items arriving damaged. Meeting the buyer in person allows me to answer any questions they may have and provide a more personal experience.

Though this is not a definitive guide to selling, I hope these pointers and ideas will help when you decide to sell (or buy) your antique or vintage mechanical clock.

Tick Talk Tuesday #33 – buying a vintage grandfather clock – advice for a reader

Tick-Talk Tuesday is about the letters and comments I have received from you, the reader, concerning your clock, issues you might have had, challenges you face, a clock you would like me to profile, my advice on your particular clock concern or a general clock question. For those comments and questions that stump even me, I consult within my clock circles for the best possible answer

MB wrote

“Hi Ron,

I came across this clock and your blog and have fell in love with it. I want to put a bid on it but have no idea what it is worth. Could you give me your opinion please?”

I am not sure whether they fell in love with the clock or my blog!

I replied,

Hi and thanks for writing.

The clock you wish to bid on appears to be American-made and from the 1990s. Let me point out some factors to consider.

If the clock is from the 1990s, the movement (the mechanical works) have reached the end of its service life. Typically movements from this era have a life span of about 25 years. If it is a non-working clock, it is worn out. If it is a working clock there is not much time left on the movement. Regardless, to service or replace the movement would be in the order of $450 to $500. If it has been recently serviced (disassembled, wear issues addressed, repairs made, reassembled, tested and oiled) or the movement has been replaced with a new one, that is a big plus.
From the photo I would question why the weights are at different levels. In a working clock the three weights descend together (with slight variations) through the clock’s 8-day cycle. See attached photo (right).
Many years ago it was not unusual to spend $2000 to $3000 for one of these clocks when new. Today they are worth almost nothing. The fact that this clock appears to be in a basement or garage does not bode well for its condition. The photo is not very clear but I can see wear around the base of the clock and it may even be missing the bottommost pedestal (which might be concealed by something in front of it) which also begs the question: what else is missing?
A similar clock in excellent condition with a recently serviced movement would be in the $500 price range.
A clock, such as this, that has never been serviced whether working or not would be in the $100 – $125 price range but be prepared to spend more money on it unless you can do the repairs yourself.

MB writes back,

“Thank you so much! They did indicate that the pendulum isn’t working so I guess I will stay away.

Seth Thomas #2 has stopped – cleaning and bushing work should put it right

Perhaps recognizable as one of the most common regulator clocks in America, the Seth Thomas Regulator #2 was found in many railway stations, offices. libraries and other public places across America during the last century, a testament to its accuracy and dependability. It is a robust, accurate, well-engineered, and dependable timepiece that was made by Seth Thomas from 1860 to 1950, a run of 90 remarkable years. Few clocks can claim that kind of longevity.

It is an iconic American clock and every serious clock collector wants one.

This particular clock was made between 1922 and 1929 and has a base reminiscent of the earlier 1860 version of the #2. It has Arabic numbers with spade hands. The bow-tie between the wood dial bezel and the drop is one piece while earlier versions had a 3-piece “bow-tie”. It has a seconds hand 2 inches above the center cannon. However, it is not a true seconds hand and runs off the escapement taking 80 beats to complete the “minute”. All but the earliest #2s had the pendulum mounted in the rear.

It is 36 ½ inches tall and veneered in mahogany. It has 77A stamped on the bottom right of the movement with the letter “K” underneath and has a small ST stamp near the middle of the front plate. Some versions of the 77 have lantern pinions while this has cut or leaf pinions.

It has stopped – it needs a cleaning and perhaps a bushing or two

Lately, the clock has been stopping intermittently. I would nudge the clock along and it would run 5-10 minutes at a time and stop. I replaced the suspension spring and all seemed good as the clock ran for a couple of weeks. I thought I had addressed the issue but it began to stop again!

I bought the clock three years ago. It was oiled shortly after I received it but it has not been serviced and now it is telling me that servicing is long overdue.

The movement is relatively simple in that it has 4 wheels. I disassembled the movement, pegged the pivot holes, and re-assembled it. There is wear but I have seen far worse in clocks that continue to run well. However, It appears that this movement does not tolerate wear.

Very disturbing are the aggressive, deep punch marks around most of the pivot holes. Punching around pivot holes to close them might have been an acceptable practice many years ago, but not today. The repair is crude and unprofessional.

The leaf pinions are in very good condition, wheel teeth look good and the verge has minimal wear.

Servicing the movement

In total up to 6 bushings are required.

I also discovered a slightly bent third-wheel arbour that did not take much effort to straighten.

Despite its apparent simplicity the parts are made to close tolerances and any wear has the potential to stop the clock. I don’t think this is a good movement for the novice clock repairer.

I installed three bushings on the backplate; the second, third wheels, and the escape wheel, and two on the front; third wheel, the escape wheel, and the verge pivot hole front plate.

The movement is clean, shiny, and mounted in the case for testing and minus the motion works gears.

Despite the fact that I have 4 movement test stands, none are appropriate for this movement because of the iron bracket onto which the movement and pendulum are mounted. I suppose I could probably adapt something. For now, into the case it goes for testing.

After three weeks the clock is running very well.

While the movement was out of the case I replaced both the maintaining power spring and the old cable with 3/64 inch brass weight cable. The brass cable has one feature I really like, a nylon core that prevents it from coiling. I also gave the pendulum bob and weight a polishing.

Cleaning and bushing work put the clock right. After the wear issues were addressed the clock not only runs better but polishing the brass improves its appearance.

An 8-day clock – what does that mean?

There’s something deeply satisfying about winding a mechanical clock—feeling the tension build in the spring or watching the weights slowly rise as you turn the key. That simple ritual connects you to generations past, when timekeeping was both a science and a daily habit. Among the many types of mechanical clocks, the 8-day clock holds a special place. Wound just once a week, it blends convenience with craftsmanship, offering the perfect balance of tradition and practicality.

An 8-day clock is a mechanical clock that requires winding only once every seven days. While that may sound simple, there’s more to it than just the winding schedule.

Types of Mechanical Clocks

Mechanical clocks vary in their run times. A 30-hour clock—often called a 1-day clock—needs daily winding. Many ogee weight-driven and alarm clocks fall into this category. Others, especially those with Chinese or Korean movements, can run up to 31 days. You’ll also find clocks rated for 14, 15, or even 60 days, and anniversary clocks, known as 400-day clocks, which run for more than a year on a single wind. The number of days simply refers to how long the clock will run before needing to be rewound.

_{Arthur Pequegnat Moncton 15-day clock}

Why Regular Winding Matters

If you don’t wind a clock near the end of its run time, it will stop when the mainspring or weight no longer provides power. A serviced 8-day spring-driven clock might run a day or two beyond its rated cycle, but eventually, it will stop once the power is depleted.

_{Junghans 14-day time and strike mantel clock}

When an 8-day clock consistently fails to run its full cycle, it’s a clear sign that servicing is needed. Dirt, worn bushings, or tired pivots can all cause power loss. Fresh oil alone won’t solve the issue—mixing new oil with old, dirty oil can actually worsen wear.

Professional clock servicing involves fully disassembling and cleaning the movement, repairing worn areas, reassembling and lubricating it, and testing for accuracy. Though servicing can be costly—and sometimes exceed the clock’s market value—it’s well worth it for pieces with sentimental or historical importance.

It’s normal for an 8-day spring-driven clock to lose a bit of time toward the end of the week. As the mainspring unwinds, the stored energy gradually decreases, slightly slowing the movement.

Speed Variations and Clock Design

Some clocks include a device called a stopwork or Geneva stop, which limits the spring’s range to its most consistent section of power. This improves timekeeping but is relatively uncommon today—many clocks that once had stopworks have had them removed by repairers over the years.

_{Arrows showing Geneva stops or stop works}

My Personnel Collection and the Variety of Run Times

Of the more than 80 clocks in my collection, about 30 are running at any given time. Five are 1-day ogee clocks, three have 14-day run times, and the remainder are 8-day models. Most antique and vintage clocks you find in shops or online are also 8-day clocks—the classic “once-a-week winders.”

Keeping a Regular Winding Schedule

Weight-driven 8-day clocks tend to be more accurate than spring-driven ones because their power source—a descending weight—delivers a constant force. They typically need only minor time corrections.

Final Thoughts

Winding your clock at the same time each week ensures steady performance. I make it a Sunday morning ritual to wind my clocks and make any necessary time adjustments.

Like any precision instrument, a clock rewards consistent care. With proper handling, regular maintenance, and timely servicing, an 8-day clock will live up to its name—keeping time faithfully, week after week.

Solar mantel clock servicing – just one hiccup, well, a couple actually

For today’s post, we are looking at a German time and strike mantel clock with a Hermle movement and sold in Canada under the Solar name. It has a 6″ dial and dark walnut case that would have been around $50 or $60 when new in the 1960s. At about 13” wide by 7” high by and 4” deep it is small by mantel clock standards and would fit just about anywhere in a home or office.

Solar clock, just a little taller than a beer can

It has a type 141 German movement from Hermle with a recoil escapement and 11cm pendulum (200.8 bpm). The half-hour strike on a bell is pretty sound for a mantel clock but is loud enough to be heard across the house. As a testament to its design and durability, this movement is still being produced by Hermle today.

This was not a running clock when I bought it but I thought a good cleaning was all it required. Judging from mars and scratches on the backplate of the movement it has been worked on in the past.

I took the movement out of its case to examine it more closely and I was relieved when I saw that the pivots were not plated, the bane of Hermle movements from the 1970s to the late 1980s. In those days Hermle used soft steel pivots for their movements and plated them for hardness. The plating has been known to peel off and this requires repivoting which is a time-consuming process. When there is too much pivot work to be done the movement is simply tossed out. This movement predates the plated pivot period.

I did not see any evidence of bushing work on the movement but one or both mainsprings were replaced as the barrels had numerous scratch marks on them. As is typical of clocks of this period the mainspring barrels can be removed without disassembling the movement. The winding arbours simply pull out once the rachet is removed. Mainsprings on some German clocks are a known weakness.

Hermle movement, you can see the S on the strike barrel

The movement was in very good condition with minimal wear.

The movement was disassembled, parts cleaned in an ultrasonic cleaner, the pivot holes pegged, and the pivots polished. The warning wheel is plastic and did not go into the ultrasonic machine, a cost-savings measure by Hermle no doubt on a part that has almost no load.

Hermle stop wheel — Hermle plastic stop wheel

I assembled the parts to check for wear and found that the movement required two bushings, the star wheel, backplate, and the lower drive wheel rear plate, both quite worn. All other pivot holes were within acceptable tolerances.

Installing two bushings

The starwheel bushing installation was simple enough. The center cannon wheel had to be removed so that the backplate bushing hole could be accessed. Bushing work went without a hitch.

Now for putting that centre wheel back on. An oval tension spring just below it must be tight enough but allow the arbour to move. Attempting to reinstall the brass washer was frustrating and as you can see I made some nasty marks trying to get it back into place (below photo). After several tries, I just could not get it tight enough.

Hermle movement, washer and tension spring — Hermle movement, washer, and tension spring

I attempted to stake the washer but that did not work. None of my stock of brass tubes had the correct inside diameter and I was reluctant to put a lot of work into making a friction washer with my mini-lathe.

Solar washer — Solar center wheel friction washer, not reusable

However, I discovered a simpler solution, a brass Bergeon bushing.

Hermle movement new washer — Hermle movement’s new friction washer is a brass bushing

The arbour is roughly 2.6mm and a bushing with an inside diameter of 2.5mm provided a good friction fit. The bushing is also large enough to cover the tension spring underneath. Perhaps not the intended purpose of a brass bushing but it works! In many other German clocks, there is a pin through the arbour and it can be easily taken off but not on this one.

Reassembly and testing

After test fitting all the parts it is off to the next stage, resembling the movement. When reassembling a rack and snail movement there a number of things to consider but in my view, the three most important steps are ensuring the warning wheel pin is in the roughly 12 o’clock position to permit a half-turn to set up the strike, that the strike paddle is between two star points and not resting on the point of star wheel (a strike train that starts up under load may stall) and that the gathering pallet pin is well clear of the rack teeth. On a typical rack and snail movement, all other adjustments are done outside the plates.

Then comes the testing phase which generally lasts a couple of weeks or more depending on what issues may arise.

In the meantime, I took the opportunity to clean the case and touch up some small chips on the decorator piece under the dial.

Anniversary clock repair – a replacement suspension spring

Let me start by saying that opinions on torsion clocks are divided—some people have great success with them, while others absolutely loathe them. Despite their seemingly simple design, they can cause endless frustration, which is why many clock repairers tend to avoid them. Fortunately, I seem to be one of the lucky ones.

Kundo standard size 400 day clock — _The _{Kundo Standard size 400-day clock wound once per year}

I gifted this clock to my daughter three years ago. She chose it for its intriguing visible movement and the convenience of running an entire year without winding. Recently, she moved across the country, and during the relocation, the clock “broke.” “Can you fix it, Dad?” she asked. “Leave it with me,” I replied.

400-day clocks, also known as torsion clocks, have been around for over a century. They were first produced in limited numbers in the mid-1890s, but their popularity surged after 1900. Between then and the 1980s, thousands were manufactured, becoming a favorite choice for wedding and retirement gifts—hence the nickname “anniversary clock.”

The Kundo model featured here dates back to the late 1950s or 1960s, during the height of production. However, with the advent of quartz clocks, mechanical versions quickly fell out of favor.

Kundo is a well-known name in the world of anniversary clocks. The name is a combination of Kieninger and Obergfell, a highly respected German company. Today, the company continues as Kieninger, operating as a subsidiary of Howard Miller USA.

Servicing a 400-day Clock

To service a 400-day clock, I highly recommend using the Horolovar 400-Day Repair Guide as a reference. Can you repair a 400-day clock without it? Yes, but the Horolovar guide eliminates almost all the guesswork.

This particular 400-day clock is a Kundo Standard 53, which requires a .0032″ (0.081mm) Horolovar spring. If you don’t have the time or tools to assemble the suspension units yourself, Horolovar (or most clock suppliers) offers fully assembled units. However, these come at a significantly higher cost.

Section 10 of the Horolovar guide includes templates for various clocks. These templates provide precise patterns for positioning the fork and attaching the upper and lower blocks to the suspension wire, ensuring proper assembly.

suspension spring installed on a Kern — _{The suspension spring assembly includes the top and bottom block plus the fork}

The screws on the suspension assembly are very small, so using a high-quality precision screwdriver is essential to avoid damaging them. The suspension spring is longer than needed and will require trimming to fit. Once the spring is securely attached to the fork and blocks, it’s ready to be reinstalled onto the movement.

The suspension spring assembly hooks onto the top cock and bottom weights or balls. A threaded thumbscrew on the top base slips into the top block. The bottom block has two pins to which the pendulum hangs. Next are the back spring cover and the locking guard.

Torsion clocks have pendulum locking systems that must be engaged even when the clock is moved just a few feet. Often, the result of an unlocked clock is a broken suspension spring. The locking guard on this clock is an earlier design and looks pretty flimsy in my view but it should work.

Once the spring assembly is installed on the movement it is time to test the beat. The beat should be 8 beats per minute and there should be ample overswing in both directions. A 270-degree rotation is healthy enough.

What makes the 400-day anniversary clock a great addition to a collection?

They are:

Relatively inexpensive to buy, although some models like Schatz and Gustav Becker are more sought-after and therefore more expensive.
Very quiet in operation.
Easy to disassemble, clean, and reassemble due to having few parts.
Slow runners, meaning wear is rarely an issue.
A fantastic conversation piece.
Long runners, with some lasting 400 days or more on a single wind.

What makes them less ideal:

Notoriously inaccurate timekeepers.
Can be frustrating to fine-tune at times.

Since I had previously serviced this clock, I was able to loosen the tiny screws on the blocks and fork with ease. Sometimes they can be tight and difficult to remove, but on this occasion, everything went smoothly. As of this writing, the clock has been running well for several weeks.

While it’s currently running slightly fast, small adjustments to the regulating dial will slow it down. However, there’s a limit to how much you can adjust, and it’s not a clock I would rely on for precise timekeeping.

Forestville mantel clock servicing – not fun when things go wrong! Part I

This post is about a mantel clock made by the Forestville Clock Company of Canada and some challenges servicing the movement.

In 2013 we were on a visit to the Thousand Islands and stopped at an antique store in Gananoque, Ontario. As my wife and I were strolling through the store and she noticed this mantel clock made by the Forestville Clock Company of Toronto. Somewhat plain in style it seemed to be in great shape and it was exactly what we were looking for at the time.

History of the Blackforest Clock Co. and Forestville Clock Co. of Toronto

The Blackforest Clock Company of Toronto, Ontario was founded by Leopold and Sara Stossel in 1928. Both clock movements and complete clocks were imported from Germany and sold through department and jewelry stores across Canada. Their son Ed Stossel started working part-time with his parents’ company in the 1930s and later became a full-time employee in the late 1940s.

Some assembly work was carried out in their Wellington Street East factory. Initially imported mantel clock and grandfather clock movements were installed in cases made in Kitchener (home of the Arthur Pequegnat Clock Company), but later the complete mantel clocks were imported from Germany. This arrangement was interrupted by the Second World War, which also led to a name change to the Forestville Clock Company in 1941. During the war years, the company imported its clock movements from England, the United States, and France. However, starting in the mid-1950s German factories again became the source of most Forestville clocks, with Mauthe being a major supplier.

The Forestville Clock Company was very successful during the middle decades of the twentieth century. Its grandfather clock cases and some of the wall clock cases were made in Canada. Ed Stossel retired in 1979 and unfortunately, the company survived just a few more years without his leadership.

Most Blackforest and Forestville mantel clocks still have their paper labels tacked inside the back door. This one does not.

My Forestville mantel clock

This clock movement and case are imported from Germany in the 1960s. There is a serial number on the backplate but no database exists online to date this clock. I am thinking that the movement is made by Mauthe

The pivots and bushings appear to be in good condition at first inspection. The clock keeps good time and there is a simple speed adjustment on the hairspring escapement to regulate the clock. This mantel clock is handsome, has good lines and reflects the style of the period.

Servicing the movement

After 7 years I have put off servicing the movement far too long. The rack and snail movement is relatively simple to work on with all the adjustment wheels, save the warning pin, on the outside. The mainspring barrels can be removed separately for servicing, common for movements of the 60s,

The hairspring escapement is something I will not attempt to clean. They can be finicky to work on and if the movement has been running beforehand, like this one, there is no pressing need to fool with it. It is well protected by a plastic shroud. Three screws unhook it from the movement.

While there is some wear on the time side I see at least 3 new bushings required, two on the front plate and one on the back.

When working with German and French movements one must always be very careful of the delicate pivots. Normally when I work on these clocks I am aware of how easy it is to bend or break a pivot and this clock was no exception. However, I had the movement apart and was reinstalling the gears to determine bushing wear and went about repositioning the center gear when I noticed its centre cannon front plate pivot had sheared off.

Arrow indicates center wheel with broken pivot (strike barrel removed)

I was not even aware that I was putting undue pressure on the pivot as I was carefully guiding each pivot in place with a pivot locator. However, either I applied too much pressure or it was ready to go because I broke a pivot. To give a sense of how small it is, here it is beside a pair of tweezers.

My experience with pivot repair is very limited. This is not like a broken or worn pivot on an American clock which is less challenging to repair because they are simply much bigger. This pivot is small, perhaps 0.5mm or so. Although I have bushings that size I do not have pivot wire that small and had to make do with a piece from my assortment of 0.85mm to 1.10mm wire.

Repairing a broken pivot, pivot wire is glued in place and left on the lathe overnight

I centred the arbour with a centring bit and then using a high-speed bit, drilled to about 4 or 5mm into the shaft, enough to anchor the pivot wire. Once the wire was inserted, I used high-strength Permatex Thread Locker Red to secure the wire which takes 24 hours to cure. The next day I installed a bushing in the front plate and put the gears back together to check the action of the new pivot. It is working okay. I was not convinced the repair would work but I will reserve judgment until the other 3 bushings on the time side are installed.

Can’t wait to find out if the repairs are successful? It’s a long wait but on November 25th, I will present the results.

Mauthe box clock movement servicing

It is time to service the movement on this mid-thirties German box clock. It was purchased at an antique mall in Peterborough, Ontario in May of 2017, and other than oiling, nothing has been done to it. While it has been running well since then, it is due for servicing. Plus, this little project is one of the many clock tasks that has kept me busy during the period of pandemic isolation.

There is nothing anywhere on this clock that tells me it is a Mauthe, not on the clock face or on the movement. However, the gong marked by the name Divina tells me that Divina was a subsidiary of Mauthe. It was likely sold under the Forestville or Solar name in department stores across Canada in the 1940s. There is an applique of a maple leaf on the crown so, I assume that it was made for the Canadian market.

German "box" clock by Mauthe — German “box” clock by Mauthe

As mentioned, this spring-powered rack and snail movement has no makers mark though 25226 is stamped on the front plate as well as the numbers 42 and 105; 42 the pendulum length in centimeters and 105 as beats per minute.

The front plate shows the rack and snail

CA 79/9 scratched in the lower right of the front plate is a clock-makers mark for servicing in September of 1979, presumably the last time it was taken apart for cleaning.

Both plates are 1.8 mm brass. The backplate is solid while the front plate is open. It is a robust movement that was designed to last.

An unusual feature is a spring-loaded weight on the governor. Manufacturers sometimes used a special fly that has a small spring-loaded weight attached to try to even the power curve of the strike side. The faster the fly spins, the further out the weight, providing more resistance.

Day I – dis-assembly and servicing mainsprings

Safety is paramount; first and foremost, let down the mainsprings.

The rack, snail, lifting levers, and other assorted parts are separated from the movement before the plates are opened up. The strike hammers stayed attached to retaining pins as they were just too difficult to take out. Additionally, despite my best efforts to pull the gathering pallet off the arbour, it would not budge. I did not want to risk any damage to either part.

The movement was dirty, as expected, but I have seen much worse.

Once everything was apart I reinstalled the time side to check bushing wear and found the only suspect bushing to be T2, front plate. After taking out the time side gears I reinstalled the strike side gears and found that side to be in very good condition. The pivots likewise on both sides are in excellent condition.

The movement is in very good condition for an 80-year-old clock.

In the normal course of clock servicing I install more than one or two bushings

Different sized mainsprings for time and strike

The time mainspring is slightly shorter in height and length and therefore less powerful than the strike mainspring. On many movements, both sides have the same mainspring power but this movement is clearly different. Is it by design? There is more resistance pushing the strike gears through the train in that it has to work a little harder so, one would expect a strong mainspring.

Note the difference in the size of the cut pinions below. Both are second wheels. The one on the right with the larger leaf pinion is the strike side, the left is the time side.

Each time I work on German or English movements I make it a point to scratch a small “T” on both the time barrel and mainspring so as not to interchange them. Even if both sides have identical mainsprings I note the difference as a matter of practice. If the springs are different and they are switched, the increased power of the incorrect, more powerful strike spring might result in premature failure of the time side.

Second wheels and difference in the size of cut pinions

The other possibility is that during a repair in September of 1979, the time side mainspring was replaced by a smaller, and more than adequate, mainspring.

I took the springs out of their barrels and gave each a cleaning in the ultrasonic. Once dry I applied Keystone mainspring oil to each mainspring and returned the springs to their barrels. That’s it for day one.

Day 2 – bushing work

In the normal course of clock servicing, I install at least one or two bushings. On this movement, one bushing was required, T2F. The hole was marginally oblong and I am sure the clock would have functioned fine without it but as a precaution, a new bushing was installed.

Cutting into the brass to prepare for a new bushing

I generally spread my clock cleaning and servicing over several days but the bushing work went so quickly that I decided to proceed with assembling the movement.

The only critical adjustment prior to assembling the plates is the stop wheel. The stop wheel requires about half a rotation to arrest the train during warning otherwise, all the other adjustments are made outside the front plate. During dis-assembly I made a note of the location of the wheel, at 12 o’clock, saving time and frustration and it worked just fine.

Rather than use a test stand I returned the movement to its case for further testing.

LaSalle Dura alarm clock movement cleaned and running

The Westclox Clock Company is best known for various versions of Big Ben and Baby Ben windup alarm clocks produced from 1909 to the mid 1980s though the later Chinese clocks did not compare with the better made American versions.

In the Art Deco style is the LaSalle series. Both of these clocks (above) are the model 61-C (401) otherwise known as a Dura clock so-called because of the nickel-plated, die-cast zinc cases made by The Dura Casting Corporation in the United States. There are 6 models in the LaSalle series and all use the Westclox type 61 Baby Ben, one day movement.

The second clock, sent to me by a reader, has a broken crystal, a rough case and a broken time key but the movement works. Since all parts are interchangeable my plan was to combine the best parts into one working clock.

A working clock, the product of taking the best of parts of two Dura clocks

So, I was left with a non working movement. I was intrigued by the design of the movement and the fact that many parts in this, which I believe to be the 61 number 2 movement, are interchangeable with other Baby Bens both before and after this movement was made. The date stamp on this movement is June 1930.

I wanted to know why this movement was not running. There were no obvious signs. I oiled the pivots to free the movement but had no success. The movement would run for a few seconds and stop. The alarm and time mainsprings were fine and had plenty of power but evidently not enough to keep the movement running.

My dilemma; two working movements and one good case

I let down both mainsprings. I removed the time and the alarm bridges to investigate further (3 small screws hold each bridge) and to eliminate the possibility of worn gears, broken pivots and worn bushing holes. Finding nothing I decided that a good cleaning was the next step.

I disassembled the movement, pre-cleaned and placed the parts, including the mainsprings into my ultrasonic cleaner for 20 minutes. My wife had been baking and it was an excellent opportunity to take advantage of the heat of the oven to dry the parts thoroughly.

Hairspring escapements can be tricky though I got lucky and set it up correctly the first time. After installing the balance wheel and threading the hairspring through the regulator and attaching the post the movement was in beat from the start.

Now I have two working movements and one good case, though one could call the second working movement a spare.

Baby Bens are well engineered and some parts are interchangeable. I enjoy working on these Baby Bens and will be on the lookout for more to add to my collection.

Fleet Time company of Montreal – case refinishing and 2 surprises

While refreshing the case of this relatively nondescript mantel clock assembled by a short-lived Canadain clock company I ran into two interesting surprises.

Here is a garden-variety vintage Westminster chime mantel clock from the Fleet Time Company of Montreal (Canada). Many of these clocks were sold at department stores across Canada during the pre-war (WWII) era. However, this little known Canadian clock company had a brief life. Between 1936 and 1940 the company produced a range of two and three-train mantel clocks with movements sourced from Germany but were forced to end their operations.

The Second World War took a heavy toll on this company as the source of movements dried up and so did the company’s fortunes.

Wood cases were made in Canada for some models while other cabinets were imported from Germany.

This particular clock has a Gufa Westminster chime movement and I assume most of their 3-train clocks had a similar if not the very same movement. Gufa is the Guetenbacher Uhrenfabrik, located in Gütenbach, Germany. They manufactured 400-day clocks, cuckoo-clocks and later they became the “Jahresuhrenfabrik” (August Schatz & Sons in Triberg, Germany).

Rather than advertise the maker, many Fleet Time clocks simply had the word “Foreign” stamped on the movements.

This is a clock that could easily have been thrown in the garbage and I am fairly sure that is where it was headed. While I was in the city of Halifax (Nova Scotia, Canada) to pick up an Arthur Pequegnat Canuk kitchen clock the seller took me into his garage, pointed to a clock sitting on a shelf, and said. “for $10 more you can have this one”. “Why not”, I said!

Refinishing the case

I thought I would tackle the case first. While the front of the clock looks okay, the finish on the side sections were down to the bare wood plus scratches on top really detracted from the general appearance of the clock. It was a real mess. On top of that, the left side shoulder section was completely detached and had to be re-glued. Hot hide glue was used for this repair.

Surprise #1

Rather than reproduce the dark lacquer finish I chose to sand the case down to the bare wood to see what lay beneath. To my surprise, I discovered a nicely grained, and beautifully textured grain. Enhancing the veneer with a light walnut stain is the way I chose to go because I did not want to go as dark as the original finish. Special Walnut, which has a light tone is perfect for the case and if I did not like it I could apply a darker walnut stain over it later.

Choosing the right stain; part of the case is still drying off from a wipe down with a damp cloth

The special walnut is very pleasing to the eye.

And the top of the clock.

After two coats of stain (above), here is the result.

After two coats of stain and two coats of shellac

The Special Walnut stain produced a very pleasing result. I applied one more coat of shellac, let it dry, and topped it off with Minwax Polishing Wax to produce a satin finish. Not the finish that came from the factory but it wlooks good.

Surprise #2

After cleaning the chapter ring, polishing the chrome bezel I was ready to return the movement to its case but what I should have done was test the movement beforehand.

When I received the clock I confirmed that the strike and chime functioned as they should and I assumed the time side was fine.

Broken mainspring which is not reparable

I inserted the winding key into the centre arbour and found no resistance. Hmm!

On these movements the barrels can be pulled out without disassembling the movement which certainly simplifies repairs. I pulled out the barrel, popped the back cap off, and discovered a broken mainspring. Using needle-nose pliers and heavy gloves, I pulled the mainspring out with for closer examination. No part of this mainspring is reusable and a new one must be ordered.

Occasionally when a mainspring breaks it takes a few other components with it like broken teeth, broken leaf pinions or bent arbours referred to as collateral damage. I inspected the gear teeth, pinions and arbours on the time train, gave the wheels a few spins and found everything moved smoothly, so, no damage this time. The broken mainspring is the only issue keeping this vintage mantel clock from striking and chiming again.

Mainsprings care easily sourced from a clock supplier. I waited until I built up a list of supplies for other projects then submitted the order online. German and American mainsprings are best and avoid those made anywhere else particularly India.

The movement was placed in a plastic bag along with nuts, hands, screws etc. and stored safely away until the mainspring arrived.

Two weeks later

Two weeks later, out come all the parts from storage.

Using my Olie Baker spring winder and mainspring retention collar I installed the mainspring into its barrel.

Fitting the barrel back into the movement involves moving the strike rods out of the way which is a bit of a pain, then, the barrel slides into a channel on the plate. The movement was returned to its case and the hands attached.

The strike hammers were re-positioned for the best possible sound and my guess is that the clock is running and chiming for the first time in many years. As of this writing, it has completed a number of 8-day cycles. And to top it off, it looks great!

Let’s see, $10 for the clock $19.50 for the mainspring and less than a few dollars for stain, glue, etc. A satisfying project combined with a piece of Canadian clock history.

DW writes, “Hello, my name Is DW I need to know where I can purchase some parts for my Daniel Dakota Grandfather Clock. If you know of any store or hardware place please let me know. Thanks in advance”.

My reply, “Hi DW and thanks for writing. There are a number of clock suppliers in Canada and the US but unfortunately none carry parts for Daniel Dakota clocks. The reason is that these clocks have a limited life and once they stop they are often discarded. They are also difficult to repair because no replacement parts are available and few clock repairers will accept them for servicing.

You may find someone in your area that will fix your clock but if not you have three other options. Option one is to find a replacement movement. Option two is to attempt the repair yourself and option three is to convert your clock to a quartz movement.”

Vedette Westminster chime box clock, as found

It could easily be mistaken for a typical German box clock of the period save for the attractive oval beveled lower window and lack of side windows. Vedette clocks are typically quite ornate – not this one! However, the sound of the chimes more than make up for its plain jane appearance.

There is nothing quite like the reverberating chime of a Vedette clock

Who or what is Aro Clock Company of Montreal?

I frequently take photos of clocks in antique stores. If asked I say that I have a friend who is looking for that exact clock and I usually get away with it. In Ladysmith, British Columbia I came across a Canadian clock that I have never seen before. On the bottom of the dial it says “Mfg Par Aro Inc Canada”.

Who or what is Aro? I could find very little information. They were evidently based in the province of Quebec and likely the city of Montreal. My research tells me that they made two styles of clocks in the 1960s. This one, a kitchen clock and a schoolhouse clock.

Both have 8 day Japanese trapezoid open plate time-only movements.
