Does anyone know the BPH for this movement?

Just check the hands every few hours (or days) and move the pendulum up for faster, down for slower. It's as simple as that. :)

Short pendulum clocks can take several winding cycles to regulate to the best of their ability.

This is actually a Junghans movement sold with the Gustav Becker brand after Junghans took over the Becker operations. The movement date is December 1935 (35 12).

If your beat setter has a counting application, just mark a starting point for the minute hand and let the machine count while the hand moves around the dial. About three times is most accurate. Then stop the counting when the minute hand touches the starting point again. Divide the count by the number of rotations and you have an accurate BPH count needed for the clock to keep time. Any chiming or striking needs to be disabled during the count process.

Thanks for the help. I now have the date of manufacture and a way forward to get the BPH

Well, you will need to count the teeth in the time train to get an actual number.

Or, just rate in in the usual manner and save yourself a lot of trouble, time, and possible mistakes. :)

Not if you have a beat counter Willie. My method above will give a very accurate BPH even without a pendulum (if it will run that way). Actually not my method - came in the instructions for my unit.
But I usually use your method of trial and error in the shop, and use the machine in the field ;)
