Regula Cuckoo Movement Identification

Regula Cuckoo Movement Identification

Most cuckoo clocks made after 1950 have movements that are made by the Regula cuckoo clock movement company. Any cuckoo clock made after this time has an 80 percent chance of being a Regula.

Most of the time there will be identification markings that will reveal if it is a Regula cuckoo clock movement. But to be certain use these methods for identification.

Regula Cuckoo Conversions

Here are some common measurements conversions for the pendulum length. The pendulum on a Regula cuckoo is from the top of the movement to the center of the leaf. The movement will be stamped with this number usually. It will have a stamp with a CM length usually on the left side of the back plate.

  • 19.5cm = 7 3/4 Drop
  • 23.5cm = 9 1/4 Drop
  • 28.5cm = 10 1/2 Drop
  • 40cm = 15 3/4 Drop

Two train or three train movements

If the clock has two weights that run the movement, identifying it as a Regula is simple. When we say two weights, it means on the movement only.

There may be three weights on the clock, but only two weights are on the movement itself. In other words, there are three train movements that take three weights. A three train movement would have three weights on the movement itself.

However, we are talking about two weights on the movement regardless if the clock has three weights on it. One could be for the music box. This is separate from the movement itself. If the movement alone takes two weights, we call this a two train movement.

This means the movement has two sides of gears from big to little inside the plates. One for the cuckoo and one for the time. If the clock movement itself takes three weights, this of course is a three train movement.

Two train, two weight Regula Identification

See if the cuckoo movement says 25 or 34 on it. This would be above the wheel with the spikes that make the bellows go up and down. Above this wheel and to the right a little, there will be numbers that are in a stamp right in the brass.

It may have more numbers or letters after the 25 or 34 but don't pay attention to anything but the a href="/product/regula-25-cuckoo-movement">25 or 34 for now. The 25 means it is a one day clock that takes two weights. A 34 means it is an eight day clock movement that runs on two weights.

Both of these are the most common cuckoo clock movements made in the world. The 25 or 34 identification stamp alone means it was made by the Regula factory in Germany.

The two styles of the two weight movements

The two train, two weight movements come in two styles. One with a dancer platform and one without the dancer platform. Keep in mind just because there are dancers on the cuckoo clock, it does not mean there is an attachment. This is an important distinction when ordering a new cuckoo clock movement.

The two weight cuckoo movements with the dancer platform comes with the platform already on it. The platform is available in a few heights. This measurement, or height, needs to be known if purchasing a new movement. The dancer platform height is the distance from the top of the movement to the platform base itself.

The clock may say 25 on it for one day and 34 for an eight day. However, with these same identification marks they have either the platform or no platform. Therefore, these same numbers may be on the movement regardless if there are dancers or not.

To sum Up

  • Figure out if it is a 2 or 3 train movement
  • Determine if there is a a dancer platform and if so, is it already on the movement itself.
  • On the brass back plate look for identification markings of a 25 or 34
  • Order the dancer or non dancer Regula in the 25 for a one day or a 34 for an eight day movement

Just acquired a Lotscher cuckoo clock. We cannot seem to find any picture of it anywhere so we can’t find the “name” of the design. We are curious to see how old it is and possibly what it is called. The clock has dancers, cuckoo and animals that move up and down with melodies. There are 3 chains, however the chain closest to the face of the clock just falls to the floor when we put the weight on so it seems it may have come off the sprocket (I am assuming that all 3 chains are on sprockets). Is that fixable? We do see markings 25/1-D, is the date code listed next to the 25 or 34 on the clock? I am attaching pictures, any information you could provide would be appreciated.

Hi there! I have a chalet style cuckoo clock. Inside, engraved on the movement, it says: Made in Germany, Anton Schneider Sohn. clock 859. 25-c. It also says “synth oil” on the movement. It came with a pendulum and 3 weights each of which is engraved 275. It has a dancer platform which rotates and what appears to be a music box type mechanism which is controlled by the third chain/weight. It was apparently running at a point because it was at least serviced in 4/1994 from a sticker on the back of the clock.
My question is; What is the best way to see if it works? Should I just hang the clock and put the weights on? I already thoroughly dusted and cleaned the outside of the clock case, and the movement seems very clean.Should I I oil it? Thanks for your help!

Thank you very much for your prompt response. Any idea as to the age of this clock based upon the information I’ve provided? I know it is at least 30 years old because it was serviced in 1994.

I bought my cuckoo clock in 1972 in Germany. It is an 8-day clock, two chains, no platform. The original weights are lost. What size (how many grams) should replacement weights be?

One more question: My eight-day clock needs the weights pulled up every two days. What does “eight-day” mean?
Thank you.

I have a Black Forest 8-day cuckoo clock that my father-in-law purchased in Germany years ago. It has a 3-weight Regula T.O. A72/1 movement and a 28.5 cm pendulum. It looks as if somebody tried to replace the cuckoo chain, which periodically hangs up. All three chains are of 1.2 mm brass, but while the other two chains are 46 LPF, the cuckoo chain is 44 LPF and stretched out. I’m assuming that someone replaced that chain with the wrong size, and that causes the cogs to bind.

All three weights are on the movement. It’s a Chalet style with dancers, waterwheel, and the cuckoo, with a “Der Fröhlicher Wanderer” music box.

Am I correct that I need to replace the 44 LPF chain with a 46 LPF chain? If so, where can I find the proper replacement chain?

Thanks,
Dave

Good evening, I have this cuckoo clock that I received after my mother n law passed away. Everything was with the clock but the pendulum. Can you tell me what one I need to buy so I can make the clock work. I looked inside and found that Anton Schneider Sohne I assume is the maker, and GM 1884288 1692176 regula 25- D.are numbers I found. Hopefully you can help me. Thank you! I have spent all day looking at pictures to see if I could find it, but I had no luck so I am turning to you. Thanks again, look forward to hearing from you!

Hi!,

I have an Albert Schwabe / Regula 25-8 to repair. GM 1884 288 169 2176. It is a two train clock with an independent music box, driven by its own weight. The cuckoo is driven by the mechanism, and the other little figure is driven by the musical mechanism.
The old lady that owns it has lost the eights.. I am trying to find out what weights to buy. Any advice would be most welcome.

Can you tell me what company made this movement or what I can replace it with? The plate measures 77mm horizontally across the back plate and 61.6mm vertically across the back plate. There are no markings on the movement except for “Made in West Germany 410” in the lower right corner of the back plate. Thanks for what ever information you can give me.

David, your clock appears to be one made by the ‘Cuckoo Clock Mfg Co.’, which is now out of business. The movement is one made by the AMS company. Check out YouTube, “Repairing a 1day AMS movement “ by Mark Munnerlyn.

Hello:

I have a 1-day cuckoo clock with the movement made by Regula. On the movement it is stamped 812536 and the number 20 on another area. It says “Made In Germany” and not “West Germany”, but I don’t know if that makes any difference. Someone wrote in pencil on the case 6/36. Could it be that old? Can you help me date this clock, please?

Hi, I’d like to replace a regula movement. The movement is stamped 25/76.
Other markerings are 1884288, 1892176, The weights are stamped 275 ET. bottom right is “Albert Schwab Karlsruhe
I assume that it is a regula 25 but what what length drop is it?
thanks,

Is this clock worth destroying? I want to carve my own but needed the guts. Thought it would be easiest to keep the housing and replace the accents. Keeping the dancers attached, maybe just painting them differently. Got it on eBay for less than a movement and music box.

Hi, we have a cuckcoo clock with the Regula Clock 359 movement. After being out of town for a week we restarted the clock. For some reason now the dancers just play continuously until the chain weight runs out instead of just playing on the 1/2 hour and hour. We haven’t had any issues with the clock before going out of town. Can you offer any suggestions on how to correct this issue? Thanks for your time.

I need to replace the works on my clock. It is marked REGULA 25-X GM 1884288 1692176. So I think the movement I need is the R25 but I am confused on the drop. When I measure from the top of the movement to the center of the leaf on the pendulum I get 8 1/4″. Which drop do I need?

Ronald Kaufman

I measured the drop and got 8 1/4″ The choices I see are 7 3/4″ ; 9 1/4″ ; or 10 1/2″ Mine is none of these. Which would be the best one to use? Thanks

Hi. I am trying to identify the clock movement in my grandparent’s cuckoo clock. There are no numbers/stickers on the case, the movement or on the pendulum. I have bought D Rod Lloyd’s book The cuckoo clock owners manual but can’t find it in there. I think the clock dates from around the 1960s and is a carved/nature clock. It does not work at the moment, I’ve attached a picture

Thank you in advance for any advice. I would really like to restore it but have no knowledge about clocks.

That is a novelty clock that was made for a very short time. That is about all I know about that one as it did not become very popular or mass produced.

Hi James, thank you for sharing your knowledge and experience. Can you tell me how many pendulum sweeps (tick-tocks) per minute the Regula 25 makes for it to be in correct time. I’m guessing 70.

Hello,
I have a clock i purchased new in Zurich in 1977 and am interested in replacing the movement because it no longer works.Unattended kids pulling on the chains to watch and listen to the bird have broken it. After reading your information, the clock has two weights each stamped 320.I removed the back cover looking for ID marks on the movement. The only markings are PENDELL 23.5 cm. Looking carefully, there are no other stamps to be found. Hopefully you can give me some information so I can try to either fix or replace this movement and get the clock back in working order.
Thank You,
Shanon

James,

Thanks for this very informative blog!

My Regula works are stamped “Made in West Germany.” Does that correspond to a certain date of origin range, say 1949-1990?
Also, the bellows appear to be kid-skin and work fine… is it possible they are original?

One last question: Can I run the clock without using the music box and not hanging that weight.

Thanks,

Daniel
