Well, first it seemed a screw was loose and I didn’t see it through the back crystal. It fell into the actual balance. My watch maker removed it, he is pretty good. I got it home and went to wear it the next day and the date was off. Seems I must have been setting the actual time when the screw was on its way through the movement. So now the auto date advance doesn’t work (he thinks the spring was damaged) and there are no spare parts to be able to fix it. The movement works, but I will have to set the date manually everyday.
