U. M. Müller clocks were once a familiar name in households across Europe, yet today the brand is not as widely recognized among collectors as some of the larger German makers. That is a bit surprising, because the company produced clocks that could easily stand beside the finest German manufacturers of the early twentieth century.
One area where U. M. Müller truly excelled was with their box clocks. At a time when tastes were shifting away from the tall and highly ornate Vienna regulators, these clocks offered something different—cleaner lines, practical design, and a price that appealed to the growing middle class. By the 1930s, the sleek German box clock had largely replaced the Vienna regulator in many homes, quietly marking the end of an era.
Note the count wheel location on the outside of the front plate
This particular U. M. Müller is a striking example of that transition. The oak case has a stately presence, highlighted by delicate carved inlays on the door, brass strip framing, and a fixed wooden crown. A brass bezel frames the metal dial, which carries classic spade and spear hands. The beveled glass, also set in brass, adds a refined touch. On the back, wall stabilizers ensure the clock hangs securely—another reminder that this was a clock designed not only to look good, but to perform reliably day after day.
The case itself has aged beautifully over the decades, with no noticeable scratches or blemishes. The dial, however, tells a different story. Its surface bears the marks of long service, including an abrasion between the numbers 6 and 7 where the paint has worn through to the bare metal. While it is not something that can really be repaired, it does give the clock a bit of honest character—evidence of the many years it faithfully kept time on someone’s wall.
Inside is a classic count wheel time-and-strike movement that strikes on a coiled gong. The strike is bold and full on the half-hour and the hour, but never harsh or overpowering. Like most spring-driven clocks, one should not expect chronometer precision, but this example runs just as these clocks were meant to—steady, dependable, and capable of keeping “regular” time across its full eight-day cycle.
After a careful cleaning and waxing, the oak case shows what it must have looked like when new, more than ninety years ago.
Collectors sometimes date U. M. Müller clocks using the small lion trademark on the dial. A raised tail generally indicates a clock made before 1930, while a lowered tail—like the one on this example—places it in the mid to late 1930s.
According to Schmid’s Lexikon, the company’s history dates back to 1867 in Mühlheim, Germany. Ownership changed hands several times over the years, including a period under R. Schnekenburger around 1880. The company operated as R. Schnekenburger GmbH a.d. Donau before facing financial difficulties, and acquired by Gebrüder Müller in 1923. The firm developed a reputation for building solid, handsome clocks that were both reliable and affordable. Müller clocks were competitive with other German makers such as Junghans, Kienzle, and Gustav Becker, though often at a slightly lower price point aimed at the middle-class market.
In the end, this U. M. Müller is a fine reminder of a moment when clock design was changing.As the grand Vienna regulators slowly disappeared from the walls of European homes, clocks like this stepped in to take their place—simpler, practical, and built for everyday life. Nearly a century later, it still does exactly what it was meant to do: quietly mark the passing of time while adding a bit of character to any room.

UM Muller box clock; not a household name in its time, yet U. M. Müller produced clocks that could stand proudly beside the finest German makers of the early 20th century.
German Box clocks: a journey into clockmaking history: the popularity of Vienna Regulator clocks began to wane towards the early part of the 20th century. The more modern and less ornate design of the box clock appealed to changing tastes and preferences after World War I.
After working on my brother-in-law’s clock earlier this year, I was so taken with it that I decided I wanted the same—or at least a similar—clock in my collection. I nearly succeeded when I found a comparable clock in Ottawa, Ontario, this summer.
I had been monitoring the sale of the clock for about two weeks. I assumed the seller was eager to sell, as the price dropped in $10 increments several times. When it hit my sweet spot, I contacted the seller.
Mauthe box clock
But first, let’s talk about the style of this clock—the box clock. By the early 1900s, Vienna Regulators were starting to fall out of fashion. Even before World War I, people began favouring the cleaner, less ornate look of the box clock. Its modern style fit the mood of the time, and before long, these practical yet stylish clocks had taken the place of the traditional Vienna Regulators.
The box clock design stood the test of time, enduring for over 40 years. Key features and characteristics of German box clocks are their appearance, since the box clock represents a departure from the designs of the Vienna Regulator clocks. Instead, box clocks embraced a more minimalist and utilitarian design.
They typically feature a simple rectangular or square wooden case with clean lines, a modest crown, and glazed elements, often without the intricate carvings and embellishments seen in earlier clock styles. The access door is large and swings open to the right. In the upper section of the door is a glazed panel protecting the dial, while the lower section usually contains five clear beveled glass panels. Sometimes the design is understated, as in the photo below, while other examples show a more ornate treatment.
Brother-in-law’s clock
The absence of markings other than pendulum length (45 cms) and the beat (100 bpm) stamp on the movement might suggest uncertainty, but the Divina gong confirms that the maker was Mauthe (pronounced maw-tay).
Divina was a trade name and subsidiary brand of Mauthe, used particularly for their gongs and striking mechanisms. When you see a gong stamped Divina, it’s essentially a Mauthe product, and it helps confirm the maker when the movement itself is unmarked.
My new clock has the same dimensions, dial face, spade and spear hands, and crown applique as my brother-in-law’s example, but there are two key differences and some minor ones. My clock strikes on three rods, while the other strikes on four. Is there a difference in sound between three and four rods? The answer is yes—the four-rod strike produces a noticeably richer and more sonorous tone.
Secondly, the glazed panel treatment on my clock is, in my opinion, more attractive, featuring a Napoleon-hat-style curve in the center glass panel.
Bottom glazed panel
Next, mine is missing the rod lock, removed for some unknown reason. The rod lock is important when transporting the clock, as it prevents the rods from banging together and potentially snapping off. Otherwise, I had to stuff napkins between the rods when transporting the clock.
The other clock has no standoffs, while mine does. Standoffs help keep the clock vertically aligned on the wall and prevent it from shifting from side to side and putting it out of beat. In my experience, some came with standoffs while others did not.
Both clocks have a 45 cm pendulum and run at 100 beats per minute. My clock lacks a maker’s trademark, whereas the other one displays it on the movement. Regarding pendulum length and beats per minute, I’ve seen other similar Mauthe box clocks with 42 cm pendulums running at 105 beats per minute. Why the difference, I don’t know?
It’s difficult to pin down a manufacturing date, but judging from others I have seen, I would estimate that it was made in the early 1930s.
Unfortunately, little is known about this handsome, well-preserved German wall clock, other than that it was purchased at an antique shop in Cornwall, Ontario, (Canada) about four years ago by a lovely elderly couple. After the husband passed away, his wife began downsizing and was evidently not concerned with getting top dollar for the clock.
Mauthe movement back plate, three strike hammers shown
The clock runs and strikes, though two minor adjustment issues became apparent. First, when the first hammer struck the rod, it produced more of a thud than a clear tone. Bending the hammer back about a centimeter or so resolved the problem. Second, the pendulum bob wobbled slightly, which was corrected by gently squeezing the suspension post closed with pliers. A clean, even swing transfers energy efficiently. A wobble wastes some of that energy, which can potentially cause the clock to stop.
The plan is to display the clock, run it for a short period, then remove the movement to inspect it for signs of wear. If the pivots are dry, I’ll apply oil, run it a bit longer, and ultimately proceed with a full servicing of the movement.
Occasionally I have clocks gifted to me as in the case of this lovely Art Deco-style German round-top wall clock made by Kienzle. The gift was greatly appreciated, although there was a small condition attached, which I will explain later.

There are times when people consider gifting me a clock but hesitate because of the high shipping expenses. When I tell them I’m willing to accept the clock, they often balk upon discovering how much it would cost to send it to me. Consequently, I have missed out on some interesting clocks due to shipping constraints.
Earlier this year, DN from central Canada was researching his grandfather’s vintage clock online and found a similar one, which led him to my blog. We exchanged emails about the history and condition of his grandfather’s clock and he asked about its resale potential. Based on the current market, I provided him with an estimated value.
I suggested several methods for selling the clock and offered to consider purchasing it myself if he could not find a buyer. Unaware that I would hear from DN again, it was four months later when he reached out and offered to gift me the clock, confident it would be cherished by a collector like myself. The condition was that I make a donation to a charity.
A well-protected clock
While traveling to central Canada to spend the summer, I had the opportunity to meet DN. With military precision, we arranged to meet in a small village 1/2 hour from our summer cottage. The well-packaged clock went from one car to the next. Afterward, we talked on the roadside, discussing the clock and, of course, sharing our cottage experiences. I said my thanks and drove off.
I know more about this clock than almost anything in my collection thanks to DN and the well-preserved clock owned by his grandfather and carefully stored for approximately 25 years following his passing. DN‘s grandfather, an engineer, appreciated the intricacy of the German-made clock and kept all the documentation. Nothing is missing from the clock; all the parts are intact.

Their business eventually expanded to musical instruments, including gramophones. They operated as a distributor rather than a manufacturer, specializing in supplying clocks at a mid-level scale to retailers.

In addition, there is a factory control slip and instructions for the gong protector. There are two stand-offs (upper right, photo below), but I could not find the screw holes in the back of the case to accommodate them. Perhaps they were offered as optional at the time, otherwise, why were they kept? And of course, the original key.
It is rare to buy a clock with any documentation
Overall, it is in exceptional condition for a 96-year-old clock. I could not see any tell-tale signs that the movement had been worked on, and in its assembled state, I did not observe any appreciable wear. Of course, once disassembled and cleaned, I will have a clearer understanding of any wear issues.
My immediate task is to determine if the clock can run and strike as it should. I removed the movement from its case, applied a drop of oil to the pivots, reinstalled the movement, and gave the pendulum a push. It runs well. Next, I will prioritize thorough cleaning and attend to any signs of wear.
Finally, I am making my donation to the St. Vincent de Paul Society in memory of my mother-in-law, who passed away this spring. The Society of Saint Vincent de Paul is a lay “Catholic organization whose mission is to help shape a more just and compassionate society by providing food assistance, material help for the needy, emergency relief, and addressing housing challenges across Canada”.
When my wife’s parents sold their home in a small town in Nova Scotia in 1996, they passed on a wall clock, which had been given to my father-in-law by a patient and had hung on the wall in the main hallway of their home, to his son, my wife’s brother. It has been in storage ever since then.
I hadn’t seen the clock in nearly 30 years though I have vivid memories. In the 1980s and 1990s, my wife and I would bring the kids to visit their grandparents on weekends. The clock would resonate throughout the house. It was unforgettable, by its loud ticking and the four-hammer strike marking the hour and half-hour.
Made by Mauthe, it is a 1930s-style German box clock, dark in color, reminiscent of one in my own collection. In fact, except for minor details on the case, it’s almost identical to mine.
German “box” clock by Mauthe, in my collection
My father-in-law loved the clock and had it for years, winding it without fail once a week. When it stopped, he would have someone local service it for him. He cherished it deeply, though I’m not entirely sure why. Perhaps, as a doctor, he valued it as a thank-you gift from one of his patients, or maybe he simply had a passion for clocks.
Sadly, my father-in-law passed away in 2012, and my mother-in-law passed away this year. While settling the estate, my wife and her brother started communicating on a deeper level, and the subject of the clock came up. Would I fix it?
Not this clock but a similarMauthe movement
The clock has now been passed to me for repair. I picked it up in mid-June, and my first impression was that the case was in excellent shape for its age. While the case has minor nicks and scratches that can be easily addressed, the dial is rough. Otherwise, the movement appears intact with no missing or damaged parts.
Overall, I believe the clock is definitely worth restoring. Once I evaluate the clock further I can determine what needs to be done, make any necessary repairs to the movement, and the case, test the movement, and return it to my wife’s brother. To have it displayed prominently on a wall and running again would be a testament to my father-in-law’s memory.
Although I have other projects on the go and cannot tackle this project until the fall, I am pretty excited about working on this clock. It is a perfect candidate for restoration but more importantly, it has great sentimental value.
In future posts, I will describe a step-by-step process of revitalizing the case and another on servicing the movement.
Kienzle might not ring a bell for many clock enthusiasts, but it was a major German producer of clocks for the general public.
Kienzle Uhren GmbH, was founded in 1822 by Johannes Schlenker in Schwenningen, in Black Forest region. Jakob Kienzle joined the family by marriage in 1883 and became the sole owner in 1897. He revolutionized clock production through mass production, leading to significant expansion. By 1939, the company employed over 3,500 people and produced around 5 million clocks annually. Kienzle eventually transitioned to wristwatch production and continues to operate as a watchmaker.
Kienzle wall clock C. 1930
This Kienzle wall clock was bought at auction in 2021. It was my second Kienzle, the first, an attractive desk clock from the early 1950s. But in general, I was unfamiliar with the maker. I later learned that the clock was missing some details: a case decoration above the number 12, both standoffs and the pendulum rod retainer was broken. However, the case itself is in relatively good condition.
The time and strike movement in this round top box clock is compact, with a 43 cm pendulum length and a beat rate of 104 per minute.
Kienzle movement
I serviced this movement in 2021 shortly after acquiring it. At the time I found It exhibited typical wear for its age, with the time side running relatively freely and the strike side being somewhat sluggish. After disassembly, an assessment revealed that the movement required 10 bushings: 6 on the backplate and 4 on the front. The work was completed without issues, the movement was reassembled and tested and the clock ran reliably until this year.
Front of movement
Now it has stopped. In short, I’m not entirely sure what caused it to stop.
Suspecting a power issue, I removed the movement from its case and took off the hands and dial face. I also let the mainsprings down but left enough tension to supply power. I unscrewed the crutch bridge to remove the pallets which allowed the escape wheel to run freely. So, not a power issue. I continued to inspect the wheels and pinions and found nothing amiss. While out of the case, I re-oiled the movement.
The issue seems to be with the time-side mainspring. Looking back at my notes, I serviced both mainsprings in 2021 and didn’t observe anything unusual about them at the time. However, I’ve noticed that if I fully wind the time side, the clock is reluctant to start. This issue has happened more than once. Releasing the tension of the time-side mainspring with a wind-down key allows the movement to start running again. If I don’t wind the time side mainspring completely, the clock seems to run without any problems.
I can only conclude that I did not clean the mainsprings as thoroughly as I should have. Residual dirt and grime on the inner part of the coil seem to cause the spring to seize when wound tightly. In the meantime, the solution is not to wind the time-side mainspring fully.
Unfortunately, the mainspring barrels cannot be removed separately as in the case of some German movements, necessitating the complete disassembly of the movement to replace/inspect the mainsprings in case of an issue. If it were feasible to remove the mainspring barrel independently, I would have taken the opportunity to remove the mainspring from the barrel and clean it more thoroughly.
Kienzle movement on the test stand
I am not about to disassemble the clock again as I have more pressing projects on the go but in the meantime, it will run as long as I do not wind the time-side spring too tightly.
The popularity of Vienna Regulator clocks began to wane towards the early part of the 20th century. The more modern and less ornate design of the box clock appealed to changing tastes and preferences after World War I, leading to the gradual replacement of Vienna Regulators with box clocks. The box clock design stood the test of time, enduring for over 30 years.

The German “box clock” is a type of antique clock that became popular in the early 20th century, particularly in the period following World War I. These clocks are sometimes also referred to as “box wall clocks” or “wall box clocks” due to their design and placement on walls.
German box clock by Mauthe
Key features and characteristics of German box clocks are its design and appearance since the box clock represents a departure from the designs of the Vienna Regulator clocks. Instead, box clocks embraced a more minimalist and utilitarian design. They typically have a simple rectangular or square wooden case with clean lines, a simple crown, glazed features and often lack the intricate carvings and embellishments seen in earlier clock styles.
Numerous German manufacturers, such as Mauthe, Gustav Becker, The Hamburg American Clock Company, Muller, Hermle, and Kienzle, were involved in the design and construction of box clocks.
U M Muller box clock
Box clocks employ a weight-driven mechanical movement or a spring-driven movement. For the cost conscious, spring-driven box clocks were within the budget of most households.
Whether the movements use weights or springs to power the clock’s operation, they require periodic winding to keep accurate time. The run times were typically 8 days though some were made to run for 14 days. The movement is always housed within a wooden case and is typically viewable through glazed side ports.
Kienzle time and strike box with round top
The clock dials on box clocks are typically white or silvered dials with either Arabic or Roman numerals to indicate the hours. Most box clocks have simple black spear or spade hands for better contrast and easy readability.
Mauthe box clock
A prominent feature of box clocks is the pendulum, which might be quite plain or ornate, which swings beneath the clock’s dial and is visible thorough a bevelled glass panel. The pendulum’s length is adjusted to regulate the clock’s timekeeping accuracy.
Some box clocks include a chime feature that makes a musical tone on the quarter hour while other have a strike feature that rings the hour or half-hour. A clock face with three winding arbours signifies a chiming clock, whereas a clock with two winding points indicates a striking clock. This adds a pleasant sound to mark the passing of time.
The vast majority of box clocks were produced in Germany. German clock-makers were renowned for their precision and craftsmanship, making Germany a hub for clock manufacturing during that era.
Box clocks were widely used in homes, offices, schools, and other public spaces. Their minimalist design made them versatile and suitable for various interior styles.
Daniel Dakota box clock from the 1960s
Caution should be exercised against copies. In the 1960s, the Chinese reintroduced the box clock design and inundated the market with numerous 31-day clocks, sold under various names, with Daniel Dakota being the most widely recognized brand. However, these clocks did not match the quality and craftsmanship of the traditional German box clocks. During the same vintage period, certain Korean and Japanese clocks demonstrated acceptable quality standards but most are to be avoided.
Today, German box clocks are sought after by collectors and antique enthusiasts for their historical significance, craftsmanship, and unique design. They serve as reminders of a bygone era and continue to captivate people with their appeal.
If you are interested in acquiring a box clock, it’s essential to verify its authenticity and condition, as well as consult with experts or appraisers to ensure its value and authenticity.

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.

I was hoping you could help me identify a clock I purchased at an estate sale this weekend for $10. The back of the wall pendulum clock has a intact paper label with a full size standing Ostrich and the letters H H S N. Stamped on the workings is 45/100 and 27583 It is a 4 chime clock.
That is all of the identifying marks.
Any information you have would be helpful.
I did find one post on a site called Worth Point about a clock that had HHS N (Hermann Heinrich Straussj of Nurenberg)

If you search journeymagazine on eBay’s Discussion boards under Watches, Clocks & Timepieces I asked about this antique clock movement with the initials HHS N – and got 2 responses.

Thanks for your time.”
My reply:
“Hi CL
Thank you for coming to my blog.
This is a German “box” clock style from the late 1920s. The letters HHSN stand for Hermann-Heinrich Strauss, Nürnberg. Strauss in German means Ostrich. This company were clock dealers who are thought to have used Mauthe movements (and others) in their clocks. They went out of business in the late 1920s. Your clock could have been made by almost any of the big German firms at the time, Mauthe, Kienzle, Junghans etc. The movement looks like a Mauthe and that makes perfect sense. 45 refers to the length in centimetres of the pendulum (17.7 inches) while the number 100 refers to the beats per minute. 27583 is a production number and the first two digits are likely the year the clock was made.
4 -rods mean the movement will produce a very nice bim-bam strike if the hammers are aligned correctly on each of the strike rods.
It is a clock worth preserving and a steal for the price you paid.
Hope this helps
Ron”

Thank you for this knowledge! I appreciate the quick reply. I look forward to getting it cleaned and hung on our wall.”
It is time to service this very fine German box clock by U. M. Muller. I have been stalling for too long. I am a little leery because the last time I worked on one of these the strike tension spring broke (my fault) so I made a promise to be more careful this time.
I bought this clock in 2013 and while it has been very reliable and running daily, like all things mechanical it requires attention from time to time.
A little background.
German “box clocks” effectively spelled the end of the Vienna regulator period because they were cheaper to produce, had simpler lines and appealed to the middle class consumer of the 1930s.
U M Muller box clock
According to Schmid’s Lexikon, the original founders of this company in Mühlheim started in 1867. It was acquired by R. Schnekenburger around 1880, then by Gebrüder Müller around 1896 when it became Uhrenfabrik Mühlheim vormals R. Schnekenburger. In 1900 it assumed the name Uhrenfabrik Mühlheim, Müller & Co. or UM Muller.
This U. M. Muller box clock features wood carved inlays on the door, metal dial, wall stabilizers, brass bezel trim, spade and spear hands, beveled glass framed in brass and a fixed wood carved crown. The case reflects excellent quality.
Logos are helpful in dating a clock. U. M. Muller clocks can be dated by the lion logo on the clock face. If the lion’s tail is up it is pre-1930. On this clock the tail is down which puts it is in the mid to late 1930s.
Back of movement
Okay, enough of background; let’s get on to servicing the movement which is the subject of this post.
U M Muller movement, front plate
It is a count wheel strike which is not unusual but to be honest I was a little surprised and expected a rack and snail movement for a 1930s clock.
The movement has been opened at least once, perhaps more. I could not see any obvious signs of repairs, so, perhaps a cleaning or an adjustment was all it required. It was very oily and I suspect it was sprayed with some sort of solvent. Despite the “wet” condition of the movement it is actually in very good condition.
I had two issues with disassembly. One, I could not pull the count wheel off its arbour despite my best efforts, so on it stayed. I simply worked around it. It made for an interesting installation of the cam wheel bushing. Secondly, the strike lifting lever spring snapped when I disassembled the clock. See, this is what I feared!
I salvaged what was left of the spring, which is essentially a stiff, straight wire that hooks onto the strike arbour, but had to drill a new hole in the plate adjacent to the old one to secure the spring. The remaining spring happened to be just long enough to do the job.
Spring repair for U M Muller movement, solder used to secure the spring in place
The movement was disassembled and parts placed in an ultrasonic cleaner. After drying all pivots were polished.
Mainsprings
The powerful mainsprings are a weak point in German clocks of this era. Usually when they break they take a few things with them. It is called collateral damage and manifests itself in broken wheel teeth, bent wheels, arbours and so on. As the mainsprings were in top shape with plenty of power, no splits or cracks, they were cleaned and reinstalled in their barrels.
Bushing work
The movement required 3 bushings, the escape wheel front and back and one on the cam wheel, strike side. It was actually not as worn as I expected and likely could have gone on further without stopping but the bushing work and overall servicing including a good cleaning will certainly extend the life of this clock.
The three 2mm diameter bushings required for the plates are some of the smaller ones in my supply. Not a huge problem but they are so small that one snapped out of my tweezers when I grabbed it from the container. It is on the floor….somewhere!
Wheels are in place and ready for the top plate
Otherwise, the bushing work went well.
Testing
the movement was assembled and while the time side ran well the strike side was out of adjustment. With count-wheel strikes it generally takes a couples of attempts to get it right but I think I have only one adjustment to make, relocating the stop wheel so that the stop pin is in the 12 o’clock position. I will leave it and test the time side for now.
Next day
This is the day when things go horribly wrong.
I let the mainsprings down and opened the plates to relocate the stop wheel. In my haste to reassemble the movement I bent one of the pivots on the governor. I knew it right away because when I had the plates back together the train would not turn and the fly was “stuck” in one spot. Out came the wheels and once I attached the fly arbour to the chuck of my lathe and gave it a few spins I could see how much it was bent. It was not bent by much, but any amount will stop the train. I straightened it as best I could and it looked pretty good. The pivots are tiny and care must be exercised when moving the wheels around when assembling the plates. It is a hard lesson for all clockmakers.
The lion’s tail is downward
Of course, while straightening the fly arbour the tiny fly retention spring, which is a small wire, flew into the room somewhere. I had to fashion a new fly spring from 19 gauge wire. What else could go wrong! Thankfully nothing else did.
This should have been a relatively easy movement to work on. Instead I seemed to have encountered one problem after another but with each problem I arrived at a solution. Despite my issues this is a well made German movement and really nice to work on.
All is well, the movement is running and striking as it should.
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
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.
Spring-loaded weight on the governor
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 bushingReady for the top plate
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.
Clocks have been more than just timekeepers throughout history; they are reflections of art, culture, and technological innovation. Whether for practical use or decorative appeal, clock styles have evolved to match the tastes, craftsmanship, and technologies of their times. Here’s a look at some of the most iconic and varied clock styles.
The clock is an instrument designed to keep and indicate time. It is one of the oldest human inventions. The clock has evolved through the ages from sundials in ancient times to early tower clocks of the 14th century weight-driven clocks and finally spring-driven clocks from the 1840s to the 1970s.
The world of mechanical clocks encompasses a wide variety of styles, and distinguishing between them can often be confusing—such as understanding the difference between a shelf clock and a mantel clock. In this article, I’ll navigate through these terms and highlight the most common styles or types, using examples from my own clock collection to illustrate them.
Mantel Clock
Many auction sites and even professional websites use the word mantle. The correct terminology is “mantel”. A mantle is a shawl or coat worn by women, an important role passed on from one person to another or the earth’s crust. A mantel is the top framing of a fireplace or a shelf above a fireplace opening.
A mantel clock is designed to fit on top of a fireplace or shelf. A mantel clock can be time only, time and strike, or a chiming clock. Generally, if there are 2 winding arbours it is a time and strike clock, if the clock has 3 winding arbours is it a chiming clock that is, it will play a tune on the quarter hours, the most common being the Westminster chime.
Mantel clocks might also be referred to as shelf clocks or buffet clocks.
Kitchen Clock

Kitchen clocks are often referred to as gingerbread clocks or parlour clocks. At times, it can be difficult to differentiate between a kitchen clock and a parlour clock. Gingerbread clocks are distinctive because their designs are typically created by steam-pressing the wooden front face. However, some clocks, like the one above, are made using a powered cutting saw but are still classified as kitchen clocks. Additionally, some of these clocks included alarm mechanisms. The terms gingerbread, kitchen, and parlour are often used interchangeably.
Another type of kitchen clock is shown below. This is an 8-day time-only delft wall clock made by Forestville.

A parlour clock is generally considered more ornate than a kitchen clock, although it may still be referred to as a kitchen clock. It is placed in front hallways, entryways, and so on. The designs are always cut and there may be finials, a mercury-filled pendulum or very ornate design, garish trim pieces, and a decorative tablet.
Vienna Regulator
Gustav Becker two-weight Vienna regulator
There are many styles but most are of the single-weight or two-weight variety. The definition of a Vienna regulator is always open to debate but the consensus among collectors is that they are weight-driven, made in Austria/Germany, ornate in design, have porcelain dials, decorative crowns, large pendulums, and finials on the top and bottom.
The broad definition of Vienna Regulator includes those that are spring-driven. Though not defined as “regulators” it is acceptable among collectors to refer to them as a Vienna style.
Cottage Clock
Canada Clock Co Hamilton Cottage Extra
Sometimes called a mantel clock or a shelf clock, they are usually diminutive in size to occupy a smaller space. They are found in bedrooms and kitchens and are sturdily built since they are often designed to be portable. They come in time only, time and strike, or may have an alarm function.
Carriage Clock
French Carriage Clock
Carriage clocks are portable and were very popular around the turn of the 20th century. French-made carriage clocks are more collectible and fetch generally higher prices although American ones can be quite desirable. Carriage clocks are designed to be portable and are time-only but some are time and strike (with a repeater function) while others may have an alarm function.
Crystal Regulator
Ansonia Crystal Regulator
Crystal Regulator clocks are identified by a brass case with 4 crystals or glass panels. Porcelain dials, Roman or Arabic numerals, ornate in design but sometimes quite garish. Most are 10-12 inches in height though some are smaller. Makers are American and French though French crystal regulators are called four-glass clocks and tend to have higher value. Distinctive by their mercury or faux mercury pendulums. Some have visible Brocot escapements and the time and strike movements are always visible.
Cuckoo Clock
Cuckoo clock
These clocks are pendulum-regulated and make an automated sound like a cuckoo when it strikes the hours. Some can be very intricate with several animated characters. Desirable ones are antiques from the Black Forest region of Germany. Modern ones are generally frustrating to repair, cheaply built, and are poor timekeepers.
Lantern Clock
Converted lantern clock
A lantern clock is a type of antique weight-driven wall clock, shaped like a lantern. They were the first type of clock widely used in private homes. They probably originated before 1500 but only became common after 1600 and in Britain, around 1620. They became obsolete in the 19th century. The one pictured above has been converted into a fusee movement.
Alarm Clock
Baby Ben alarm clock with seconds hand
Alarm clocks are wound once per day and designed to do two things, wake you and display the time. They are cheap, and are average timekeepers but have long-lasting and reliable movements.
Desk Clock
Kienzle World Time clock
These sat on fancy office desks or credenzas in office locations. They are either time-only or time-and-strike. Most were time-only to minimize distractions in the office environment. Some are very attractive and have unique designs and are more decorative than utilitarian. This one above is called a World Time Clock by Kienzle.
Wall Clock
German Mauthe Box clock
A wall clock is broadly defined as any clock designed to be hung on a wall, making it a practical and visible timekeeping solution. Wall clocks come in various styles, from simple and functional designs to highly decorative pieces. This one by Mauthe is often described as a German “box” clock which became popular after the First World War and made into the 1940s.
Schoolhouse Clock
Ansonia schoolhouse clock
They are known as schoolhouse clocks because they hung in many schoolrooms in North America. Usually distinctive by their octagon shape and short or long drop feature with a glass door displaying a swinging pendulum. Many thousands were made; they had cheap mass-produced softwood cases and robust movements. Most were time-only though some were time and strike and others even included a calendar function.
When they were marketed years ago they were not called “schoolhouse clocks” but rather, clocks made for the schoolroom.
Novelty Clock

These clocks are designed for the tourist trade with interesting features. In the case of the above clock, a smiling Mao Zedong has his little red book in hand and is waving “to the masses” as the clock ticks.
Ogee Clock
Waterbury OG clock
It is so-called because of the curved molded wood case. It might also be referred to as an OG clock. The design originated in the United States in the 1830s, distinguished by a case (usually pine) the front outer edges of which are curved into an S-shape (Ogee). This shape is formed by the union of a convex and a concave line. A mass-produced variant of the shelf clock, the Ogee clock typically stands about 30 inches (75 cm) high and is usually weight-driven. The movements were generally made of brass (earlier ones were made of wood) and ran for 30 hours or eight days. This is a 30-hour weight-driven version from the 1870s.
Tall Case Clock
Ridgeway Hamilton Country, Westminster chime
Tall case clocks are known by various names depending on the region. They are referred to as tall-case clocks in American terminology, long-case clocks in British terminology, hall clocks in Canada, and sometimes as floor clocks. However, the most commonly used term is “grandfather clock.”
They are usually weight-driven, with the weights on chains or cables, and are distinctive by their obvious height. They are always 6 feet or over but can be as high as 8 feet high (1.8 to 2.4 meters). They often feature elaborately carved ornamentation on the hood (or bonnet), the frames, the throat, and the dial or clock face. Older ones have 30-hour movements but all modern grandfather clocks run on an 8-day cycle.
Smaller clocks are called grandmother and granddaughter clocks. They are under 6 feet.
Anniversary Clock
Kundo standard size 400-day clock
These clocks are also called torsion clocks or 400-day clocks. 400-day clocks are torsion driven having a long suspension spring to which a weight oscillates back and forth. Typically these clocks operate at 8 beats per minute and run for long cycles on a single wind, up to 400 days. These clocks were popular as wedding gifts or gifts to mark special occasions. They are relatively simple to repair but can be finicky to set up. The newer quartz clocks are very accurate but do not replace the charm and curiosity of the older mechanical ones.
Some might call them purely decorative.
Tower Clock
Tower clock in Holguin, Cuba
In the early 14th century large mechanical clocks began to appear in the towers of Italian cities. There is no record of any working models preceding these public clocks that were weight-driven and regulated by verge-and-foliot escapements. They are referred to as Turret clocks in the UK.
In conclusion, while there are sub-categories for some of the clocks described above, this overview provides a general understanding of the commonly used terms. Having this knowledge can be especially helpful when shopping for a special gift or identifying the style of clock you may have in your possession.
