Schatz 8 Day Cuckoo Clock

November 16, 2007 | By | 67 Replies More



I just overhauled a Schatz 8 day cuckoo clock. The movement is model 50 (has a 50 in the circle on the back plate). The customer has the top piece, so I could not include in in the photo. The nicely made movement has some surprises!

  • The movement plates are very classy with the design of a bird worked into them,
  • Separate controls for door and bird – bird goes in and out with each cuckoo while the door stays open,
  • The cuckoo and time train are on the opposite sides of the movement, compared to the majority of cuckoo movements,
  • Very large teeth on the time first and second wheels.

The weights are 2 lb, 12 oz. and 2 lb, 14 oz.

My job no. 4492. This clock had probably seen years of use, as many of the pivots needed to have wear removed and be polished. I installed 14 bushings.

The circle on the back plate says:


The rectangle says:


Jahresunherfabrik means “Year Clock Company”. This was the company’s name for many years, as they started out as a manufacturer of 400 day or “Anniversary” clocks. In the early 1950’s they became known as Aug. Schatz and Sohne.


The photo above was made before the movement cleaning, as the dirt in the engraving makes the lettering show up better!

    Hi….I have a Schatz wall clock with pendulum and two weights. It was my grandmothers and I want to make it work but it is missing one weight. The weight is 7 12′ long and 1 5/8″ diameter. Do you have any idea how to replace one or both weights?

    Hi – I have a Shatz 8 day, with “50” written in back of case, including a few penciled numbers.
    It was my grand clock and only ever owned by her.
    I have heard the bird chirp and the bellows still move up and down etc, but it has not been in a wall in more than 35 years.
    It’s a dark wooden Maple version. Smallish.
    I know you don’t give out valuations but an indication of varying prices and sales would be helpful –
    For insurance. Thanks

    No, the 50 represents the year this movement was introduced, 1950. For this clock to be only 25 years old, it would have been made in 1988, but Schatz was out of business by then. It was definitely made in the 1950s.

    If you look at at Schatz’s 400 day clocks made in the 1950s, they are marked “Germany” not “Western Germany”. See, for example, the clock in the following post:

  8. Gaspar Ramsey says:

    I think this means that they have been making clocks for 50 years. Had the clock been made in 1950, it would have been marked “Made in Western Germany.” It is not old enough to have been made in the prewar period, and the reunification of Germany was 1990, after which the marking became “Germany” again. This clock is less than 25 years old, which is not a bad thing in cuckoo clocks. They are toys, you know.

  9. Bill Stoddard says:

    Most people have these clocks repaired for their sentimental value, or because they really like the clock, as repair will cost more that a similar new clock. I offer a repair service for these clocks, please see the following web page:

    I just bought a Shatz 8 day Cuckoo Clock at a yard sale for $5.00 It is is missing one pine cone weight. Is it worth trying to find th eother weight and having the clock repaired? If so where should I go to find a replacment weight and have the clock looked and repaired if possible.

  11. Bill Stoddard says:

    How much do the unlabeled ones weigh? The Schatz weights I have measured varied from 2 pounds 12 ounces (1247 grams) to 3 pounds 5 ounces (1502 grams). The 1500 weights are OK to use, the lighter ones may be the original weights (if the weight is correct) as the Schatz weights aren’t labeled.

  12. Jill says:

    Which weight do I use

  13. Jill says:

    I have two sets of pine cone weights both of different weights,my clock is a eight day. one of the pine cones is stamped with 1500,the other has no stamp

  14. Bill Stoddard says:

    Grasp the HOUR hand near the center and turn it to point to the hour that the clock is cuckooing. Then move the MINIUTE hand forward to the correct time, pausing each hour and half-hour for the clock to cuckoo.

  15. Christine says:

    My cuckoo charm is off by 2 cuckoos too many??
    Any help pls?

  16. Jim says:

    Yes to all the bellows move freely and makes the cuckoo sound and the bird moves up and down freely. It was just shipped to me by my Uncle. He lives in New York and I live in Texas. It had a lot of bubble wrap around it.

  17. Check that the bellows go up and down freely, and that the cuckoo bird goes in and out freely.
