Regula Cuckoo Movement Identification

Posted on    Posted in  turned_in_not  Uncategorized

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 be stamped 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 spiked wheel that makes the bellows go up and down. Above this wheel and to the right a little, these numbers will be stamped 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 is dancers on the cuckoo clock, this does not mean they are attached. 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 attached. The platform is available in a few heights. This needs to be measured 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, it is attached to 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

Have a 1920 – 30 cuckoo. The pattern of the movement suggests it is a Regula 02. The movement isn’t identified but the pattern of the plate is certain. Is there any literature or specs available for these ?

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
