I have about six 950b watches, including an early "gold train" watch. They don't make them like the 950b any more.

I have a 950 that bound up that was my granddads he was a breakman, my dad gave it to me to try to fix, might you have any suggestions? The crown wheel and the nearly will turn but not past a full tooth, he said it bound before and he had it sent out and fix it worked for a while and just stopped again.
