Fellow Collectors,
I recently purchased a Wakmann 7 jewel aircraft clock in working condition. As I was picking up my briefcase it slipped out from a height of two feet onto a carpeted floor. It no longer runs. I removed the movement from the case and the balance moves freely in one direction but not the other so I do not believe that the balance staff was damaged and the balance jewel is properly in place. What might be some causes of the problem and is this something that can be easily rectified. I read on the message board that overbanking might cause this. The movement itself appears to be in excellent condition and it appears that I might be the first one to have opened it up.

Thank you,
Artillero

If the staff didn't break, may be because the movement has shock protection. A photo would assure of that.

If the impulse jewel has jumped over the pallets, the balance cock will have to be removed/lifted so that the roller with impulse can be realigned correctly. It is a job that requires a skilled watch repairer.
