This should Urwerk in an old wall clock, because the original was destroyed. The clock is not so important, has rather nostalgic reasons why they should be running again. Since it was quite expensive, it should be a brand drive. Ordered, delivered, installed and ..... does not work! Of course installed in the right battery and safety pin .... no so not to draw there. The drive means of adjusting a little back and forth and asked .... running! The next day: clock is! The same procedure and running again. The game I have yet to looked at two days, then out to the drive (battery inside left) and return. After a week in the corner I want to send back the movement, because I hear it softly, softly ticking ... If it be considered to be working? And Whether! After the replacement nor the clock and asked impatiently waiting for the next day. The next morning, the first look at the clock: Waaaahhhnnnsssiiinnn which is still going! A week later tested clock - goes to the minute! Now several months have passed and I had not even set the clock - it still goes down to the minute and a tick will only be heard if you dransteht very close. Sometimes you have to give the art a 2nd chance.
