N.B. We are not watchmakers we come across watches during the pursuit of other business interests.

The first day I tested the watch it ran and kept excellent time, the next day I wound it, the watch runs but the hour and the minute hands do not move; they can be moved manually to change the time. I have tried to open this with  a watch knife but I can't it may need a special tool. The band is the original leather Bucherer band but it is showing quite a few signs of wear.  The watch is approx'y 3cm square. There is only light scratching on the glass.
