In Flanders Fields, the poppies blow Between the crosses, row on row, That mark our place; and in the sky The larks, still bravely singing, fly Scarce heard amid the guns below.
Today is a day of remembrance. Exactly 100 years after the end of World War, at the 11th hour on the 11th day of the 11th month on Sunday, Canadians will observe two minutes of silence — as they do every year on this date — to remember soldiers (and other military personnel) who lost their lives in this war and other conflicts.
People wear artificial poppies on their clothes in the weeks leading up to Remembrance Day. Red poppies symbolize the memory of those who died. On November 11, special church services are organized. These often include the playing of “The Last Post”, a reading of the fourth verse of the ‘Ode of Remembrance’ and two minutes silence at 11:00am. After the service, wreaths are laid at local war memorials.
National War Memorial, Ottawa, Ontario, Canada
The official Canadian national ceremonies are held at the National War Memorial in Ottawa. A service is held and wreaths are laid by armed services representatives. In May 2000 the remains of a Canadian soldier who died in France in World War I, but was never been identified, were laid in the Tomb of the Unknown Soldier at the National War Memorial.

Take a moment to remember those who made the ultimate sacrifice to protect our freedoms.
Every horologist should have sturdy clock stand for testing clock movements.
If you have Gene’s movement test stand to test your clock movements you have chosen one of the best stands for clock repair. It is well-built, adjustable and simple to use. It is one of the best test stands I have ever used but it is not perfect.
While Gene’s test stand is excellent for mantel and shelf clock movement testing it is not ideal for most wall clock testing. I was tired of propping the movement stand up with books and pieces of wood to gain height so I decided to address the problem by constructing a cheap and effective extension for testing those movements with long pendulum rods which includes many wall clocks that I enjoy working on. I initially thought about building an entirely new stand for wall clock movements but building an extension to Gene’s stand made much more sense.
Although this extension addresses a shortcoming of Gene’s movement test stand, should you require something taller for grandfather clock movements you can easily modify this one to suit your needs. I do not work on grandfather clocks; the size is right for my purposes.
Frame constructed of plywood and spruce board1/2 inch C shape platform
The extension consists of four legs, three of which are braced approximately midway on each side and the back with a lower brace along the bottom front. It has a plywood platform on the top where Gene’s stand rests.
Gene’s stand is mounted atop the extension
The extension has no adjustments although leveling can still be achieved on the Gene’s stand by means of the 4 adjustment bolts on the bottom part of the stand
A clamp (or 2) secures the stand to the extension
The extension has no adjustments although leveling can still be achieved on the Gene’s stand by means of the 4 adjustment bolts on the bottom part of the stand. The legs are 1/2″ by 1 1/4″ spruce. The extension measures 18 1/4″ high by 9″ deep by 9 1/4″ wide. I used carpenter’s glue and for extra rigidity and 1″ screws (pre-drilled holes) to secure all the pieces together. I sanded it and applied a clear topcoat to give it an attractive finish. This is a project that took me less than two hours.
Simply attach the extension when you need it. A clamp or two can be used to secure the stand to the extension but I might design something more effective later.
You need some form of stand to test movements and if you do not have one, I highly recommend Gene’s Movement stand. The extension makes it even better. Let me know what you think.
The ultrasonic cleaner is an essential tool for clock repair. Yes, you can get along just fine without one but if you have some spare cash you will not be disappointed.
Ultrasonic cleaning machines are used by a wide variety of professionals where cleanliness is of paramount concern. They are used in many industries including Dental/Medical, Industrial, Firearm, Jewelry/Watch/Clock, automotive repair and so on.
For the past two years I have been struggling with a Harbor Freight “special”, a light duty machine that does a less than average job of cleaning clock parts. It was inexpensive and I thought it was all I needed. Now I am done with it. It was frustrating to use, the cleaning cycle was a short 6 minutes, the heater produced lukewarm water, there was no drain, the basket was made of plastic and at the end of the day it did a poor job of cleaning clock parts. It was time for a replacement.
Harbor Freight Ultrasonic cleaner
My research included visiting manufacturers websites, looking at a myriad of models on on eBay and Amazon and seeking the opinions of clock enthusiasts on Facebook and the NAWCC forum site. There are a plethora of Chinese made machines at very attractive prices. They offer powerful heaters, large basket capacity and the ability to drain the solution from the tank. I have no idea of the reputation of these companies and I could have just as well bought a machine which would fail on delivery or fail in 6 months to a year. I would then be faced with spending another few hundred dollars to replace it. I also dreaded the thought of chasing after a Chinese company for warranty work.
I found L&R Ultrasonics. They have been making commercial quality ultrasonic cleaners for a number of years. They offer a range of sizes. I chose one near the bottom of the line, the Q140. The Q140 is approximately 10 inches long by 6 1/2 inches wide by 8 1/2 inches deep. It has a .85 gallons capacity (3.2L). It has a heater, a mechanical timer that sounds like an egg timer, a drain and it operates at 43kHz. It is made in the USA and costs twice as much as a comparable Chinese cleaner. It is a robust, well made machine backed by a 2 1/2 year warranty and something that should give me piece of mind for many years. A little money can be saved by buying an ultrasonic cleaner without a heater and preheating your solution in a microwave oven but the heater is a nice bonus.
Made in the USA
One negative, it did not come with a stainless steel wire basket which I had to purchase separately from another supplier. The L&R basket was over CDN200! For a fifth of the price I opted for an after market stainless steel mesh basket by Cambridge Time that is designed to fit the Q140.
Enough room for Gilbert time and strike plates plus the gearsBack of unit showing fuse, drain hose and clip for plastic drain hose
Overall, it is well designed, quiet (reasonably), portable, simple to use and well constructed. It uses a basic 60 minute mechanical timer and a simple on-off switch for the heater. One downside is that it is smallish and will accommodate only one movement.
Can you get along without one? Yes, but it makes life so much easier.
At 2:00am Sunday morning, the 4th of November, set your clock one hour behind. That is, if you live in Canada. Your time change date may vary according to the country you live in. Consider yourself lucky if your your country does not observe this archaic convention.
If your country uses Daylight Saving Time (DST), you must change your clocks twice a year.
Seth Thomas Regulator #2 wall clock
“Spring Forward – Fall Back” is a phrase most often heard in the USA and Canada. In North America the word “fall” is used to denote the season, while other English-speaking countries call it autumn. Set your clocks forward 1 hour in the spring at the start of DST (Daylight Saving Time), and 1 hour back in the fall when DST ends.
Records show that the phrase “spring forward, fall back” has been in use at least as far back as the early 20th century. It is the practice of advancing clocks during summer months so that evening daylight lasts longer, while sacrificing normal sunrise times.
Is this attractive 30 hour weight driven Ogee a Waterbury, a New Haven or an E.N. Welch? All of the above, actually and perhaps more.
The older the clock and the greater the number of owners means there is an increased chance that there have been minor and even significant changes to the clock
Is it a marriage or a Frankenstein?
When horologists speak of a marriage they mean the clock in its entirety is not original. It generally means the movement is not original to the case but it can have other meanings as well. Various parts and components might have been added or changed over time. Over the life of a clock it has often been in the hands of many owners particularly if the clock is well over 100 years old. The older the clock and the greater the number of owners means there is an increased chance that there have been minor and even significant changes. Each owner may add or take away components in the interest of having a reliable clock while sacrificing authenticity. Functionality trumps aesthetics. When a clock goes well beyond the horologists definition of a marriage, it is called a Frankenstein.
A Frankenstein clock is made up of a mixture of clock parts from many makers. In this case, a previous owner acquired a number of non-working Ogee clocks, took what was salvageable from each one and constructed a working clock.
New Haven 30 hour movement
This clock was purchased at auction as a non-running example and cost the owner very little money. I was asked to take a look at it and perhaps “do something to make it run”. It came complete with weights for both sides missing only the pendulum bob and the correct key. The key that came with it was a #3 mantel clock key as the original would have been a crank style key. One weight was stuck in the right channel past its hook; the other was loose in the case; not a good way to transport a clock. Though difficult to tell if they are original to this clock, the weights are those typically found in a 30-hour brass time and strike movement.
The numbers have been repainted by the writer
The dial is not original to the case though it is correct for the period. There is a stamped impression in French on the back of the dial suggesting that the clock it was attached to was intended for export to France (Chauncey Jerome?).
Tablet design
The tablet is a nicely detailed floral design but has some loss as one would expect given its age. However, the tablet and the door do not appear to be original to the case. There are small blocks under each hinge suggesting the door was “made to fit” this case. Nails are used on one hinge and screws on the other.
Waterbury coil gong
The case is an E.N. Welch, the time and strike weight driven movement is New Haven and the coil gong is a Waterbury.
The aluminum spindle for the cable just above the movement on the right side is an curious touch.
Aluminum spindle
A wall hook at the top and back of the case suggests that it was hung rather than having sat on a shelf. Knowledgeable Ogee clock owners know that these clocks were never meant to be hung though many were displayed in that manner.
I took the movement out of the case, inspected it for wear and found it to be in very good condition with no obvious pivot, tooth, pinion or click wear. The verge and escape wheel similarly had little wear. The cables for the weights should be just long enough to bring the weight to the bottom of the case with a little to spare. On both sides the cables were twice as long as they should have been. The suspension spring and rod which is a later replacement, is too long as the bottom of the spring touches the crutch loop. The crutch loop had been incorrectly turned 90 degrees requiring a simple twist with pliers to correct it. How it ran is a puzzle since there was no impulse transmitted from the crutch to the pendulum rod. A previous owner, though well intentioned had little knowledge of how a movement functioned.
Incorrect grain direction on top piece
The rosewood veneer though dulled with age is in fair shape and had acceptable repairs with the exception of the flat horizontal strip on the top front, which upon closer inspection, is a replacement with simulated grain oriented in the wrong direction. Other issues are minor chips on the bottom edge of the case, two pieces of missing veneer on the right side and slight bubbling of veneer on the top left side panel.
Veneer issues
So, what is this clock exactly?
The answer is that it is a 30 hour Ogee clock. It is also an amalgam of many clock parts, a Frankenstein. From afar the entire clock looks very good, but closer examination immediately reveals it many sins. As they say, “Nice from afar but far from nice!”. A resourceful person took all the good parts from a variety of clocks and combined them to make a clock that actually runs and keeps good time.
Is it a keeper?
For discerning clock collectors this example is far from acceptable and certainly diminishes the value of a clock considerably even if it runs well. An expert looks for precisely these things prior to any decision and any serious collector of Ogee clocks would instantly walk away. For someone either interested in the history of clock production or those entering the world of clocks wanting a cheap clock to practice and learn with, it is certainly worth keeping.
The clock is running strongly and striking as it should following a cleaning and oiling. This 30 hour New Haven, Waterbury, E.N. Welch Ogee clock from the 19th century would fool most people.
It reminds me of that old expression….Caveat Emptor (Let the Buyer Beware)!
When people ask about my clock collection their first comment is, “Do you have a cuckoo clock”. No, I say and their reply typically would be “You should have one!” I often wonder why folks think I should have one. I suppose many collectors have at least one in their collection. Now when they ask I can now say, “of course I do”.
sellers are interested in a sale and do not need to know anything about the clocks past
Thank you, Uncle Dave.
I have acquired most of my clocks at flea markets, auctions, word of mouth etc., even had a few given to me but I know little about their history. The sellers are interested in a sale and do not need to know anything about the clocks past; unfortunate but it is what it is.
This is not any old cuckoo clock. This one is especially important……to me at least. This one can actually talk to me. I’ll explain.
My cousin Dave (we called him Uncle) died in 2017and his family knew that he loved his cuckoo clock. Rather than give or sell it to a stranger they decided to hand it over to the family clock guy…..me! Dave was related through my father’s father and has a cottage next door to ours in the province of Quebec. Dave was a helluva a guy and he would do anything for you. He loved life and cherished it to the end.
From time to time you will find service dates written or stamped inside vintage or antique clock cases. These dates give you an indication of the age of the clock and how well it was cared for over the years
In the early 1970s, he and his wife went to Germany for a tour, returned to Canada and regretted not buying a German cuckoo clock. So, he promptly went to the Cuckoo Clock Shop in Ottawa (our nation’s capital) and bought one. He also wanted it in running order. Over the years whenever it stopped he had it promptly repaired.
Back of clock
he history of an object is a window to its past. This clock is a common 30-hour cuckoo clock made in West Germany in July of 1975 (photo below).) and thousands of these were made and sold all over the world. It has a Regula movement, still made to this day. Regula movements are made by SBS-Feintechnik, and are dated by a letter code. This one has the letter “V” which indicates that it was made in 2007.
German made 30-hour cuckoo clock
The clocks complete service history is recorded on the back panel. When I opened the back access door to inspect the movement and the condition of the bellows I found all the dates when the cock was brought in for repair. From time to time you will find service dates written or stamped inside vintage or antique clock cases. These dates give you an indication of the age of the clock and how well it was cared for over the years.
Detailed service history behind the access panel
Oct 10, 1978, clean oil adjust, major repair
Sept 22, 1988, CXO (clean and oil) adjusted by “AO”
October 30, 1990, new movement, repair by “AO”
Jan 1996, 5996 (job #) clean, oil & adjust
April 27, 2007, 9869 (job #) new movement and chains
From the service records, I observed that the clock is on its third movement. It is often simpler (and cheaper) to replace the movement in a cuckoo clock rather than to repair it. Attempting to repair a cuckoo clock is very time consuming, frustrating, and costly. In addition, if the entire clock had to be shipped, the case usually incurs extensive damage as it makes its travels. This is the reason most clockmakers no longer accept most cuckoo clocks for repair.
Regula 1-day movements typically cost less than CDN120. The cost of servicing a two-train clock locally is CDN225 and up, so, replacing the movement is a logical decision.
Cuckoo clock bellows on left and right.
I oiled the movement, installed the weights and now it is a lovely little 1-day clock that dutifully cuckoos on the hour.
We have a number of clocks in our summer cottage and my wife and decided that that is where it should hang. Everyone who visits marvels at the sound of the cuckoo clock, it is so distinctive. Now they say, “that’s a nice cuckoo clock, where did you get it?”.
It is not perfect. Sadly at some point in every cuckoo clock’s life, it needs the bellows replaced and these bellows are brittle and in poor condition. A cuckoo clock that does not cuckoo is, well, just another clock! The bellows is a cottage project for next summer.
If one were to ask those with a keen interest in Canadian antique clocks, the word Pequegnat would immediately come to mind. Pequegnat produced clocks for close to 40 years and left an indelible mark on Canadian culture.
Predating Arthur Pequegnat is a lesser known clock maker (or clock-makers) that made clocks between 1872 and 1884. The Canada Clock Co, and the Hamilton Clock Co. struggled over a 12 year period to put Canada on the clock-making map. In 1872 the Canada Clock Co. established itself in Whitby, Ontario (Canada) but lasted just 4 years before failing, though largely due to a devastating factory fire.
Canada Clock Company cottage clock
Out of the ashes came another attempt in 1876 and key principles including manager John Collins moved to Hamilton and set up the Hamilton Clock Company. After 4 years this new company also failed and production halted in 1880. In late 1880 one more attempt was made to establish a new company called the Canada Clock Company resurrecting the old name. It is still based in Hamilton at the old Hamilton Clock Co. factory. Success was short-lived as the company declared bankruptcy in 1884 ending a dozen years producing clocks for the Canadian market.
Although both movements and cases were made in Canada they were copies American styles
Canada Clock Company, Prince of Wales parlour clockCanada Clock Company, City of Hamilton parlour clock
I have grouped the clocks from the three companies and these are their characteristics. The most common clocks found today are the weight-driven, thirty-hour “Ogee” style, with colourful birds or flowers surrounded by a black background on the glass tablet. At least five different labels are known, four have a beaver on them. The large printed paper label was located inside the case on the lower back. Spring-driven mantel clocks with plain cases were also made with thirty-hour movements. Although both movements and cases were made in Canada they were obvious copies of American styles.
Hamilton Clock Co Gothic steeple clock with etched glass tabletClock label showing the Hamilton Clock Company factory
Also produced was a spring-driven “school house” wall clock.
At least sixty models of spring-driven mantel clocks are known, with both thirty-hour and eight-day movements. Most of the door tablets (Canada Clock Co.) have acid etched glass designs, unique to the two Hamilton-based companies and done in association with a local glass factory. Wall clocks are also found with the Canada Clock Company, Hamilton label.
The most desirable clocks are the ornate time and strike parlour clocks such as the City of Hamilton and Prince of Wales pictured above.
Unfortunately, a valiant attempt to grow a home-bred clock company failed miserably. However, the clocks of all three companies are highly sought after by Canadian collectors today.
This is a Canadian made clock I bought at an antique store on Bloomfield, Ontario this past summer (2018).
Arthur Pequegnat kitchen clock
This clock is affectionately known as the “Pointed Top”
The Arthur Pequegnat Clock Co. made clocks in Kitchener, Ontario (Canada) from 1904 to 1941. Canadian clock collectors are very familiar with the name and associate Pequegnat clocks with solid construction, robust movements, conservative designs and nationalism since many clocks were named after towns and cities in Canada.
Pequegnat made mantel, shelf, hall clocks (Tall case) and wall clocks mostly of oak but some were mahogany veneered. The Kitchen clock or gingerbread clock as it is often called was very popular at the time and Pequegnat made an effort to keep up with current styles with a range called the Maple Leaf. There were six versions of the Maple Leaf clock made by the Arthur Pequegnat Clock Co. Though the dimensions are similar they share two unique characteristics; all Maple Leaf’s have the distinctive maple leaf tablet and Maple Leaf pendulum. It is Pequegnat’s interpretation of a truly Canadian clock styled after American clocks.
Label found underneath the base
This clock is affectionately known as the “Pointed Top”. Maple Leaf clocks are easily found on auction & for-sale sites and can be had for a mere fraction of the cost of the more desirable hall and wall clocks.
Hammer and coil gong
I have several Pequegnat clocks in my collection, two of which are Maple Leaf’s, a “fan top” and now this, the “pointed top”. In my view, the pointed top is the best design of the series.
Made of quarter sawn golden oak, it is reminiscent of a Gothic steeple clock, with squared columns on either side and a pointed centre with stylistic applique above the 5 inch dial. The base is a simple angled pedestal sitting on a box frame.
Pendulum bob with Canadian Maple Leaf
Some clocks have something peculiar about them and this one is no exception. Most Pequegnat labels are found on the back board. The label on this clock is underneath the base which is an odd location for a Pequegnat. If this was a standard practice it looks original and has the usual amount of loss one would expect from a 100 year old clock label. While the name Berlin is on the dial, the label indicates that the clock was made in Kitchener, Ontario. There are two possible explanations; either the dial face is a replacement from a older clock or the clock was made during the transition period (1916) when the name of the city was changed from Berlin to Kitchener during the First World War.
The movement is a distinctive Arthur Pequegnat movement with nickel-plated steel plates and brass bushings pressed into the plates
The glass tablet is in excellent condition. It is not uncommon to find some loss especially a few missing maple leaves here and there but this is the best I have seen. The dial face has some flaking but is otherwise in good condition; the Roman Numerals are vivid and unfaded. The spade hands are correct for the clock and look original. The oak case is in great shape with no missing or split pieces. The finish is in excellent condition and the oak grain enhances the simple lines, in fact, this clock has aged very well.
Tablet is in excellent condition
I took the movement out of its case to inspect it. It is a distinctive Arthur Pequegnat movement with nickel-plated steel plates and brass bushings pressed into the plates. Not surprisingly it had been worked on in the past. One bushing on the front plate has punch marks around it otherwise the movement was tight and there appears to be little evidence of wear. There is one small issue however; the lever that activates the passing strike on the half hour is loose in the arbour and has turned to one side. Turning it to the correct position does little to fix the problem. At some point I will get in there with Lock-Tite to secure it.
The fact that it does not strike reliably on the half hour does not particularly bother me. I oiled the movement, reinstalled the movement into its case, set the beat, wound it and it maintains a full eight day cycle.
I am very pleased with this acquisition but I my search goes on for the more desirable 15-day Pequegnat Moncton wall clock and of course the Regulator #1.
A few months ago I was following a NAWCC thread on the volatility of clock prices and thought I would echo comments from some of the posters as well as my own thoughts on why clock prices are seemingly all over the map.
Market conditions and demand play a significant role. I have watched sadly as prices for many early American clocks have plummeted yet high end clocks have retained their value. Theories abound including tough economic times and the newer generation’s rejection of anything old.
As one poster said, “How is a price arrived at? It is a murky and confusing process. People use a number of metrics including a price consistently achieved at auction and their own experience buying and/or selling. Most offer clocks for 2 to 3 times what they expect to receive knowing that they will be negotiated down because it is much harder to mark something up. It is a very inexact science and a source of much debate. An object is ultimately worth what someone is willing to pay.” That’s especially true of a truly rare clock for which there is no real comparison. The term “rare” is difficult to define but rare is what most “experts” generally agree upon.
However, what was once considered “rare” based upon the largely anecdotal experience of persons whether they are dealers, collectors or auctioneers has been changed by the “eBay effect” where rarity is challenged by many examples offered for sale. It has been a real game changer.
Sperry and Shaw New York style clock for $75
Another poster said, “Many people who deal in antiques and collectibles cannot know everything.” It is especially true in the blossoming low end line of antique shops which are no different than flea markets and junk shops. Many of these stores rely on impulse buying and clock experts are not their target customer.
The poster went on to say, “These clocks are not intended be sold to a serious collector, but the impulse buyer will make the clock purchase based on any number of factors – decorative; “That steeple clock would fit perfectly on the mantel” or “We don’t care that it might not work, it is for show only” or nostalgic; “We always wanted an old clock and we can now afford it”. You cannot discount the value of being able to see the object up close, smell it, touch it and hear it tick and or strike.”
A true clock store, usually with repair services, commands high prices for their wares, but the clocks usually come with a guarantee and the comfort of knowing that it will work well and will do so for years to come. Internet stores lack the fixed and variable costs (and reputation) that a brick and mortar establishment has and, all other things being equal, can offer their product at a lower cost. However, to make a true cost comparison, one should add the cost of shipping, packaging, handling and insurance that will need to be paid by the purchaser.
Is this an antique store or a junk shop?
I cringe as I walk into some of these shops. Most antique malls that I’ve discovered charge a monthly rate plus a commission percentage that result in significant markups. I spotted a Mauthe box clock priced at $300.00. It had a marred dial, broken beveled glass panels and marked “as-is”. When I asked the dealer about a better price, his answer was to knock 10% off. I walked away shaking my head.
There is no true “standard” pricing for any vintage or antique clock. As with most objects there is a price range that most would consider reasonable. I have paid more for some clocks than they are worth but armed with increased knowledge I can now make more informed decisions in the future. Caveat Emptor is the principle which should guide every buyer. The buyer alone is responsible for checking the quality and suitability of goods before a purchase is made. Education is the key as an informed buyer will make much better choices.
This is a 30 hour or 1-day New Haven Ogee shelf clock. 1875-80 seems to be the approximate period of manufacture for this smallish Ogee clock. The case measures 18 1/2 by 11 3/4 inches (47cm X 30cm) and the hour strike movement measures 3 1/2 by 5 inches (9cm X 12.7cm).
So, its a bit of a miss-match. Imperfect but attractive just the same
This 30 hour New Haven Ogee shelf clock looks nice from a distance but closer inspection reveals a number of issues regarding the condition of the case. Although the sides panels of the clock are veneered, the front veneer has been stripped likely because of significant loss or damage. Crude chisel marks on the left front of the case suggest that the veneer in this section was tough to take off. This is unfortunate, but I have no intention of re-veneering any part of this clock. There is also veneer loss on the top right side. From a distance the entire clock actually looks good and the casual observer would not notice the difference.
It takes a#3 key to wind the clock. It is probably the only American shelf clock I have that uses a key that small.
The movement looks original to the case and there are indications that it has been worked on in the past. There are punch marks surrounding several pivot holes, an common old-style repair to close the holes.
30 hour movement, prior to cleaning
The coil gong is a replacement and is in a slightly different location than the original gong judging from screw holes to its right. The gong is probably from an E. N. Welch or a Gilbert. The clock dial face is a recent addition and the access door knob looks like it is a later addition.
So, its a bit of a miss-match. Imperfect but functional.
The movement was dis-assembled and the parts cleaned in my recently acquired Quantrex 140 ultrasonic cleaner. The movement parts came out shining particularly the lantern pinions.
Front plate removed
The pivots were in very good shape and polished up well with my Butterworth Bushing Polishing System that I use with my multi-speed Dremel tool. I decided to tackle only the worst bushing holes; the centre canon, back plate and the escape wheel bridge. Four bushings were also installed on second and third wheels, front and back plates.
Movement testTesting in the clock case rather than on a stand
Some consider 30 hour clocks as a hassle because they must be wound once a day but I am okay with that. This 30-hour Ogee clock runs very well, keeps good time and I am pleased with the servicing.
I posted Part I of a four-part article on this curious schoolhouse clock recently. In this, Part II I discuss the what I like and what frustrates me about this project.
I have a vivid memory of this Waterbury octagon short drop schoolhouse clock that hung in my grandparent’s kitchen when I was a young boy. Now that I have it what do I do with it. I thought long and hard about what my next steps should be and considered advice from friends and family.
Do absolutely nothing,
Discard the case, buy a donor case and install the parts I have or,
“Preserve” it, that is, not change it in a significant way but have a working clock.
I had hopes of restoring this clock to its former glory but after discovering a home-built case I have decided to proceed differently
The good stuff: The dial face is definitely showing its age. There is rust and pitting throughout but the Roman Numerals are fairly clear despite some fading. The Waterbury trademark is visible on the dial just above the centre arbour. The spade hands appear to be original, though rusted. The time and strike movement is intact sans suspension spring, pendulum rod and pendulum bob. There is a Waterbury trademark on the front plate of the movement with a patent date of September 22, 1874. Just how long Waterbury used this movement deserves some research but the clock works look to be from the 1890s. The coil gong is clearly marked Waterbury. The bottom line; there is strong evidence that the movement, dial, bezel, clock hands, and coil gong are all from the same clock.
When I picked up the clock I immediately discovered that it was twice as heavy as it should be
Plywood was not available as a general building material until 1928
The frustrating stuff: When I picked up the clock I immediately discovered just how heavy it was. Makers go to great lengths to make clocks as light as possible; this one is very hefty. The backboard and front face are constructed of ½ inch plywood. Plywood would not have been available in the 1890s or even some years afterwards. The centre frame appears to be 3/4 inch board. The movement sits high on a block of wood to bring the arbours closer to the dial but the result is that they protrude too far above the face. Robertson and Phillips screws (the former invented 1909, the latter in 1932) are used everywhere. The “newer” case is very sturdy and would likely last a long time but weighs twice as much as it should. It is an interesting homemade case.
Plywood construction, twice as heavy as a typical clock case should be
The handyman, be it my grandfather or someone who it was passed on to certainly had the best of intentions. The original pieces such as the dial, movement etc. were retained but the original case was discarded. My grandparents were poor and lived modestly. In those days if things wore out folks would go to great lengths to keep them running often resorting to home repairs with materials at hand. The goal was functionality not aesthetics.
The movement, coil gong, dial face, bezel and hands are all from the same clock
Four screw holes were drilled into the original brass dial bezel and at one point in its life it was painted red. The bezel would have been originally hinged to the front face of the clock. The dial glass is missing, perhaps discarded after it broke. Aside from the 4 screws holding the dial bezel, I counted 20 more screw holes once I lifted up the bezel.
Lastly, the short drop section is without an access door.
Next steps: I had hopes of restoring this clock to its former glory but after discovering a home-built case I have decided to take another course of action.
The dial, bezel, movement and coil gong are the important mechanical bits which are in good shape. Missing are the suspension spring, pendulum rod and pendulum bob, all easily available through any clock supplier. The movement wheels run free and the mainsprings are good; all the parts are there aside from those mentioned above and there is no reason why it should not run reliably after cleaning and servicing.
The clock is waiting for me on my cousins kitchen table
The case is what it is, it is part of my history, part of my family history. It will be sanded and stained dark walnut followed by a clear topcoat. I will affix a brass plaque in memory of my grandfather and proudly hang it on the wall.
But first: The first order of business is to clean up the clock including the brass dial face sections. Next, buy new glass for the dial and a hinge for the bezel plus the movement parts that are required. Finally, I will fashion a new drop door using old wood from a donor clock.
And that’s where it ends. It can be no more than what it is.
It may not be the prettiest clock in my home but it will be a great conversation piece and after 70 years it will finally tell the time. I can only imagine my grandfather standing under the clock, comparing the time with his pocket watch and deciding if he should make just one small adjustment.
The clock is now on my project bench and I will post two more blog articles in November detailing the steps towards preserving this interesting clock.
Photo of my grandfather’s clock sent to me by my cousin
I’ve thought about this clock, dreamt about it, wondering where it was all these years…….and now I have it. Now, what do I do?
I have a vivid memory of this Waterbury octagon short drop schoolhouse clock that hung in my grandparent’s kitchen when I was a young boy. After church on Sundays, my father would take us kids by for a visit; it was a weekly ritual. The house was stone quiet except for the sound of a clock ticking loudly in the kitchen. My grandfather was a veteran of WWI and was bothered by certain noises but did not mind the sound of a mechanical clock.
When I was a kid in the 1950s it looked gigantic and for some curious reason, it was painted yellow with red trim. What did I know, I thought old clocks came in all sorts of colours.
My grandfather, William George Joiner, taken during WWI
But he loved that clock. There is a story that my grandfather was fanatical about keeping the clock on time; he would constantly compare the time to his pocket watch and make adjustments, sometimes several times a day. They left the house on Olmstead Street in Eastview (now Vanier, Ontario, Canada) several years before his death and the clock was passed to a son (my uncle) and eventually handed down within his family. My grandfather passed away in 1962.
Movement is essentially intact except for the suspension spring, rod and pendulum.
A year ago I decided to track down the clock and learned that it had stayed within the family. My cousin sent a photo of the clock but upon examining it I could see that something was not quite right. It was missing parts, it looked pretty rough and that case looked homemade. At that time I replied,
Yes, it is indeed a Waterbury time and strike clock. Your description of it as a school clock is correct though it would not have been called a schoolhouse clock at the time. It would have been sold as an office clock. The patent date tells us that the clock was made after 1874 but likely manufactured in the 1890s to 1900.
In clock circles it would be described as a time and strike 8-day octagonal short drop wall clock, Roman Numeral dial face with spade hands. From the photo I can see that it is missing the pendulum (as you said) the hinged wooden drop access door which would have had a glass tablet and the brass/glass bezel which would have covered the dial. I assume these items are long gone.
It also appears to have been in a damp environment judging from the tarnished brass and the fact that the rust from the iron nails has bled through the wood. However, it is not unusual for a clock of this age to be in such a condition. I have seen far worse.
At a recent family get-together, my cousin said that if I wanted the clock I could have it. Yes, I said and I brought it home thinking about my next steps with my new clock project.
There are 4 posts in this series. Part II is in 4 days. In Part II I consider those next steps. Parts III and IV will be in November.
The family was in the process of downsizing and this was one of the items that had to go
This attractive antique Victorian style German wall clock was purchased locally from a family that once lived in the town of Parrsboro over 100 years ago. Parrsboro is a picturesque Canadian community in Cumberland County, Nova Scotia and one of the oldest settled areas of Canada. It had hung for many years in the Parrsboro Mansion pictured below. Today the mansion is a popular bed and breakfast destination.

I found the clock on a local online for-sale site. It looked interesting but there was no price listed. I contacted the seller but they were asking considerably more than I was willing to pay. I explained the work that had to be done to the case and movement and the fact that had it been in better condition they would easily receive more for the clock. I concluded the phone conversation with my top offer for the clock. They contacted me 4 days later and met my price.
I was curious about its history. The seller explained that the clock was brought over from Europe when her husband’s family moved to Canada in the 1890s and had been in the family ever since. The family was in the process of downsizing and this was one of the items that had to go. I was pleased that the seller expressed an interest in seeing the final restoration and I assured her that I would keep in touch. Knowing the history of the clock, or any clock for that matter, is value added in my view; provenance is so important when it comes to any antique.
Using the serial number and trademark I have determined that it was made between 1890 and 1910, consistent with information provided by the seller
It is a Mauthe time and strike wall clock with an Adler gong. I have been assured that the clock is original in every way and using the serial number and trademark I have determined that it was made between 1890 and 1910, consistent with information provided by the seller. The eagle emblem on the Adler gong suggests that it was made after 1898. The turn of the century would be fairly accurate dating for this clock. It is a 120 year old clock that is not overly garish and reflects the style its period.

The clock case is in need of a restoration. There are pieces missing and it appears that it was either in a hot environment for some of its life, an attic perhaps or hung over a fireplace; the finish is alligorated. Alligorated finsihes are those that have encountered heat damage and are characterized by a finish (shellac or lacquer) that softens and pools into globules collecting dirt as it re-hardens.
Alligorated finish
It is missing a finial on the crown, a trim piece on the top of the access door, the wall stabilizers and a corner piece on left side of the crown. Some of these parts are available through parts suppliers, other pieces must be fabricated.

I am anxious to start on the case and must decide whether to clean the surface or strip to the bare wood. The dial is a separate issue. It is cellulose and very dark. Can it be cleaned? Not likely but I am doing some research to find a solution. In the meantime the movement has run strong for the past 4 days and strikes as it should. It will need a cleaning and possibly new bushings but I will know more once I examine it more carefully. At this point I do not see any major issues with the movement.
I am completing the restoration of a Waterbury wall clock and once done I will commence work on this clock project.
As I proceed with this project I will document my experiences restoring this early 1900s FMS Mauthe time and strike wall clock with an interesting history.
Found this little schoolhouse clock not 10 minutes from where I live. It is a Sessions Drop Octagon. It was manufactured in Forestville Conn. USA in the early 1920s and spent most of it’s life hung in a one-room schoolhouse near Springhill, Nova Scotia (Canada). The seller said that he had taken it out of the schoolhouse when it was decommissioned in the 1970s and it has been in storage ever since.
It is small, measuring 21 inches high by 13 1/2 inches wide and with a 7 inch Arabic dial.
Foxing
“It’s not running” he said. “Fine” I said. I took it home and had it running within 10 minutes. Although it ran strongly it required a good cleaning. I took the movement out of its case, dis-assembled it, cleaned all the parts in an ultrasonic cleaner, polished the pivots, cleaned and oiled the mainspring, installed 2 bushings, reinstalled the movement, tested it and set about cleaning up the case.
Time-only movement
After a Murphy’s Soap clean-up to the case I let it thoroughly dry then applied 2 coats of shellac to bring back the natural luster of the wood which was in otherwise good condition. The clock face had some foxing, which, in clock circles, means that some of the tin byproduct had leached through to the paper label and discoloured it. A little unsightly but I decided to live with it. I hung it up over my desk as one of a trio of time zone clocks to remind me of the time where my kids live.

The clock is a loud ticker but it runs well and should be reliable for years to come.

Though by no means a definitive guide the following are some important dates in the history of the clock as gathered through a number of sources. The difficultly in affixing some dates with precision results from discrepancies among sources.
Horological developments during the centuries before the mechanical clock are left out altogether. Water (Clepsydra) and sun clocks of the middle ages and astronomical clocks of ancient China deserve special mention but are the subject of a separate discourse and are not included here.

The clock is one of mans greatest achievements. The development of instruments to tell time is the unwavering toil of brilliant minds from many disciplines who, over 800 years, worked tirelessly to create, innovate and improve methods for telling the time.
Horology is not only the study of time but the synergy of art, joinery, fashion, design, décor, physics, engineering, metallurgy and mathematics. Indeed, the study of the mechanical clock is a microcosm of our society.
Arthur Pequegnat Regulator #1 is still on my wish list
Lots of exciting news over the summer. Six new clocks, three of which have been on my wish list for a while. One, a Cuckoo clock, is my first. Another is an Ansonia crystal regulator, two more Pequegnat clocks, a curious Waterbury wall clock and more. I will be writing about my new acquisitions in the weeks to come.
I also managed to expand my clock library as I have found several interesting books on horology which I will report on in a future article.
For those who wrote to me over the summer, thanks and again I apologize for the delay in getting back to you.
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 or a clock you would like me to profile and my responses to your questions with advice on your particular clock concern. For those comments and questions that stump even me, I consult within my clock circles for the best possible answer
BJ writes,
“What did you do to fix the balance on the older Hermle movement? My local clock man would not repair and I love the sound of my clock. The spring has come away from the top – ok, I took out to try to adj the inner ring and dropped it. ( it was losing an hour a day.) anyhow, the fork also looks to have been bent.
Is this fixable? I’ve seen a few clocks on-line but did not know if they can be used to repair my movement easily.”
Hermle balance wheel escapement
My reply,
“Platform escapements and balance wheels are the work of watch-makers. I am not surprised your clock maker would not repair it. In my case I did not have to re-attach the spring but did have to adjust it. If the spring has pulled through the upper block, you could try threading it back in and in give it a little solder to hold it. If it is snapped off, that is much more difficult. Even if you were to get it back in, that would change the dynamics of the helical spring which is now slightly shorter. You can easily bend the fork back to where it was.
You have some options.
Find a donor movement on eBay or Craigslist. If it is exact, and the same model number the parts are interchangeable. However the fact that it is on eBay may mean that the clock is worn and you are no further ahead.
Go to a site such as Clockworks and compare your model number to the best fit for a new movement (if you are prepared to go in that direction) or
check Timesavers to see if they have a replacement balance wheel.
If you should get it up and running or if you find a donor movement you may find the above article to be of some help.”
BJ writes back,
“Thanks for the article. I wonder if I can get a watch maker to take a look. Good idea.”
Chinese time and strike wall clock that seller calls a grandfather clock
Antique Grandmother Clock in Immaculate Condition
I am selling my wife’s grandmother clock because it does not suit the decor of our new home. She has treasured this antique for years and doesn’t want to part with it. Please make my execution as painless as possible and buy this clock quickly. Keeps perfect time and has no scratches on the cabinet.
This ad will be removed when I am executed…………..actually just before ,,,,,so purchase this clock now
This is a Chinese clock with a calendar feature, circa the 1960s. The ad refers to it as an antique. It is not!. Vintage, perhaps. The ad refers to it as a grandmother clock. It is not!
Grandmother clock by CraftLine circa 19780; a little shorter than a grandfather clock
The seller is asking $150, five times more than it is worth. It’s probably fairly reliable, looks well cared for and I would take it if it were given to me.

Mauthe time and strike box clock
RC writes,
“I was looking online for information on the exact Mauthe Box clock you have. I am going through my late fathers estate & trying to find out what it’s worth. It belong to my great uncle and passed onto my dad. Every since I was a little boy I can remember this clock being at my great uncles home.
Any information you could give me would be greatly appreciated. I have attached a picture of the clock.”
This is my box clock.
Mauthe time and strike Box clock
My reply,
“You have a time and strike box clock. These have excellent movements and should run for years. A servicing would be due, however.
It might have the 3-rod “Divina gong” which, according to the standard German reference, Hans-Heinrich Schmid’s (2005) Lexikon der Deutschen Uhrenindustrie 1850-1980, is a Mauthe trade-name registered in 1912. It would have a pleasant two-tone, bim-bam sound. Unmarked box clocks like mine were likely sold as a Solar house brand by Eatons. Your is marked and was likely bought from a jeweler.
Thousands of German “box clocks” were made in the first third of the 20th century. The box clock replaced the classic “Vienna Regulator” after the First World War and reflected a minimalist approach to clock design. Most were made in Germany. I would date your to about the 1930s.
The following is excerpted from one my blog posts.
Mauthe clocks have had a long and illustrious history in Germany. In 1844 Friedrich Mauthe and his wife Marie founded the company in Schwenningen to produce watch parts. At the end of the 1860s Mauthe began to produce their own wall clocks (and movements). The Mauthe sons Christian (1845-1909) and James (1847-1915) took over in 1876. In 1886 Mauthe began manufacturing its own springs. Around 1900, alarm clocks, pendulum wall clocks, grandfather clocks, office clocks and so called “Buffet Uhren” or “Buffet clocks” were offered. In 1904 the 3rd generation took over (Eugene Schreiber (1877-1939) – son of Christian Mauthe, Dr. Fritz Mauthe (1875-1951) – son of Jacob and Mauthe Alfred (1879-1911) – son of Jacob Mauthe to build on the base of the company.
In 1925 Mauthe announced a new trademark. It shows a right-looking eagle with outstretched wings, holding in its talons a three-part round plate with the letters F, M and S.
In the 1930s the company at its peak produced about 45.000 clocks per week. About 60% were produced for export markets such as England. In the Mid-30s Mauthe started to manufacture their first wrist watches and some were supplied to the German Army (“Wehrmacht”). From 1946 on Mauthe re-started with the production of wrist watches. Shortly after that the company eventually fell into decline.
As to value, Mauthe wall clocks are currently in the $200 and $500 range depending on condition. A serviced clock would fetch more.
I would clean it up, service it and proudly display it.”
We call it Daylight Saving Time (DST), the British call it “British Summer Time” and “summertime” in other areas. It is the practice of advancing clocks during summer months so that evening daylight lasts longer while sacrificing normal sunrise times. Typically, regions that use daylight saving time adjust clocks forward one hour close to the start of spring and adjust them backward in the autumn to standard time. We have a little expression, “Spring ahead, Fall behind” to make it easy to remember what to do twice a year. In Canada, it is the second Sunday in March and the first Sunday in November.
Mauthe buffet clock
The idea was proposed by George Hudson in 1885 and first implemented by the Austrian Empire in 1916. Some countries do not recognize it in all regions. In Canada, for example, most of Saskatchewan does not change clocks spring and fall, it technically observes DST year round. Parts of Nunavut remain on Eastern Standard Time throughout the year. In the USA (which has 11 time zones) most areas observe DST with the exception of Arizona and Hawaii. Florida has recently applied to get rid of DST.
I advocate a move to “permanent daylight saving time” that is, staying on summer hours all year with no time shifts
DST clock shifts sometimes complicate timekeeping and can disrupt travel, billing, record keeping, medical devices, heavy equipment, and sleep patterns. Computer software often adjusts clocks. Radio controlled clocks adjust the time automatically which is very convenient. We have two modern Sony clocks in our home which do exactly that.
My only tall-case clock, Ridgeway, Hamilton Country
But for the 35 clocks that I have running at any given time, that means making a manual adjustment twice a year which is time-consuming and an unnecessary hassle.
There is a constant dispute about the benefits and drawbacks. Proponents say that it conserves energy and has a psychological benefit of extending the daylight hours. Opponents say that the energy arguments are inconclusive. People must remember to change their clocks which is a time-consuming exercise, particularly for antique and vintage mechanical clocks that cannot be moved backward safely.
For most of my clocks I either simply let them complete their cycle, stop them and when the correct time shows on the clock, I start them up. There is less wear and tear on the movement and I think my clocks are happier for it.
But why go through this nonsense; let’s just get rid of DST! I advocate a move to “permanent daylight saving time” that is, staying on summer hours all year with no time shifts. My clocks will appreciate it and yours will too!
If you ever need to transport a German box clock or a similar style wall clock there are several steps you must take before you remove it from the wall.
German “box” clock by Mauthe, sold under the Solar or Forestville name in Canada
One of these procedures is to secure the strike rods. The gong or strike rods are screwed into the gong block. If allowed to move during transport there is a risk that the rod(s) will break. Although they are strong and withstand years of striking they are also brittle and can easily snap. Clock-makers have several solutions for securing the rods. This is one of them. Yours may be similar.
The gong block
On some clocks, you may find a fork-like device that turns to secure the rods.
Strike rod stabilizer
By turning it clockwise the three gong rods will fit into the forks as shown in the next photo.
The pendulum is removed and rods are now locked in place
Once the rods are secured in place and you have removed the pendulum rod and bob as well as secure the access door, you can now safely remove your clock from the wall.
There are four general categories of clocks; quartz, electro-mechanical, electric, and mechanical. Mechanical clocks, whether they are antique or vintage are the focus of our discussion on why a clock runs slow.
We are quite accustomed to the accuracy of quartz clocks which lose or gain mere milli-seconds per week. Contrast that with an era when folks were content to accept that their mechanical clock would be a minute fast or slow through the week and it was a common practice to make small adjustments over the run cycle of a clock.
In fact, a typical American spring-driven clock in properly serviced condition may gain or lose a couple of minutes per week as a norm. Weight-driven mechanical clocks that gain or lose several seconds per week are considered to be very accurate.
That said, how many mechanical devices do you know run perfectly (relatively speaking) after 120 years.
A clock runs slow for a variety of reasons.
Let’s look at some factorsand examine each one.
Environmental
Pendulum too low or too high
The pendulum is the incorrect weight
Suspension spring length is incorrect
The suspension spring is not attached correctly
Lack of lubrication
Gummed-up lubrication (over-oiled)
The balance wheel needs adjusting
A weak mainspring
Changes or alterations when servicing
Clock cycle time variance
Slipping or binding

Environmental
Mechanical clocks are subject to a number of environmental factors which may cause them to gain or lose speed over the course of a year. These factors include heat, cold, and humidity. Increasing the ambient temperature of a clock will slow it down from the expansion and lengthening of the pendulum unless the pendulum is a compensating type using Mercury or dissimilar metal rods. Denser air also causes the pendulum to move more slowly.
Moving a clock from sea level to a higher elevation will affect the speed of the clock.
Pendulum bob with inset rate adjustment
Pendulum too low or too high: The lower the pendulum the slower the clock will run. Many pendulum clocks can be adjusted either by a set screw at the bottom of the pendulum or by an inset screw on the pendulum. In the absence of an adjustment on the pendulum, there is a regulator on the clock face. Use the small end of a double side key and insert it into the dial face of the clock to speed or slow down the clock.
Shortening the pendulum will speed up the clock. Anything that increases the length of the pendulum will reduce the rate of the pendulum and result in a clock that will run slower.
Parts of the clock related to the pendulum
The pendulum is the incorrect weight: If the pendulum is too heavy it causes the centre of gravity to be too low, consequently the clock will run slower. Having the correct weight pendulum for your clock ensures smooth running.
Suspension spring length: Often, when a clock is repaired by a person who has limited knowledge of the effect a replacement spring will have on the running of a clock they will occasionally install an incorrect length or thickness of suspension spring. Choose the suspension spring that is correct for your clock.
Rate adjustment under the 12. Use the small end of the double-sided key to make the adjustment
Suspension spring not attached correctly: A suspension spring is located at the top of the pendulum rod and is the flexible part that allows the pendulum to swing. It is the connection between the top post and the pendulum leader. If it is not installed securely the pendulum may not swing at all or will wobble, robbing the movement of its energy.
Lack of lubrication: Pivot holes that have dried up means that there is no lubricating barrier between the pivots and their bearing holes although the movement may otherwise be very clean. Small drops of clock oil applied to the dry pivot holes will ensure the clock runs well and will have a long life. Without oil, the steel pivots will wear the brass pivot holes resulting in wheels that will not mesh properly eventually stopping the clock.
Note: a small drop of oil in each bushing hole is all that is required.
Gummed-up lubrication: When a clock runs slowly the first instinct is to apply more oil. Old blackened or greenish oil in the pivot holes is a sure sign the clock has been over-oiled. Although there is an almost immediate improvement in the running of the clock it will not be long-lasting. In no time at all the clock will begin to run slowly again as the new oil mixes with the dirt and grime in the old oil. When this occurs the oil becomes an abrasive paste resulting in exacerbated wear. The only solution is servicing which includes disassembly, cleaning of the movement, addressing wear issues, reassembly, and testing.
Balance wheel needs adjusting: Regulation of the escapement consists of sliding the two-small weights attached to the center of the balance wheel. Inwards for fast and outwards for slow. Hold the wheel and push the small adjustment “finger”. Moving the finger toward your right will be faster and vice versa. Moving the finger one dot represents a change of about 10 seconds per day. The movement will have a directional indicator with an”S” for slow and “F” for fast on the sides adjacent to the balance wheel.
Balance wheel escapement
A weak mainspring: Often the mainspring you will find in your antique clock is the original one(s). The steel used at the time the clock was made was generally of higher quality than the steel used today with some exceptions. By their very nature mainsprings become weak over time.
Weak mainspring are called “set” mainsprings. If “set”, your clock will not run a full cycle, 8 days for eight-day clocks, a full 30 hours for one-day clocks, or the designed cycle. When a spring-driven clock is brought in for a professional repair the mainsprings are often replaced.
Most properly serviced clocks with their original mainsprings will run their full cycle. Should your clock require a mainspring replacement a correct size quality American or German-made mainspring should provide years of reliable service.
Changes or alterations: Changing or altering the mechanism such as replacing a gear with an incorrect teeth count may speed up or slow down a clock. Although movement parts may appear to be similar, manufacturers often made small changes resulting in parts that may not be interchangeable with the exact movement over the years.
Clock cycle time variance: American spring-driven eight-day clocks will run slightly faster at the beginning of their cycle by providing most of their power and run more slowly through the week as the power of the mainspring unloads. A spring-driven clock that is one or two minutes fast at the beginning of the week is often a minute or two slower at the end of its cycle. This is considered normal and no adjustment is necessary. The power on a weight-driven clock, on the other hand, is constant and the loss or gain in time at the beginning of the cycle will be the same at the end assuming no wear issues are slowing it down.
Slipping or binding: If your clock is losing hours per day something in the mechanism is slipping or binding. If your clock is losing minutes per day after all adjustments are made, it is likely bushing wear or some other worn component is causing the problem. Clock repairers have a term called end shake. End shake allows freedom of lateral movement for each of the wheels between the movement plates. If the plates are tight and there is no end shake, too much resistance will slow a clock. It is why clock repairers always check for sufficient end-shake when servicing the wheels on a movement.
Final thoughts
Your situation may be unique and if it is not a clock issue covered by this article I suggest consulting an expert in clock repair. If you have little experience and choose to do your own work on an antique or vintage clock, the mistakes you make may be irreversible.
There is also a certain element of risk working with mechanical clocks as the power contained in the mainsprings may cause serious injury if not handled properly.
Knowing why your clock runs slowly is the first step in diagnosing the problem. Addressing the issue is the next step. Beyond that, periodic maintenance and servicing with quality parts is the key to a long life for your clock.
