Ok. So I've got a likely legit Polaris with some questionable history. Unfortunately, I don't know the original owner so I can't find out how it got it's odd characteristics.
What I do need is parts. My watchmaker has it at the moment but he doesn't want to tear into it until we confirm the availability of parts for repair. The setting mechanism seems to be stripped as it clicks when the crown is turned but the hands don't move. The alarm works and the bezel works as well as the automatic winding. It will keep time, I just can't set the hands and consequently, the date. I want to be involved in the process so I volunteered to find the parts for the repair. He gave me a parts list and some likely suspects for the problem: movement and alarm clutch wheel, movement and alarm winding pinion, crown wheel and intermediate crown wheel for alarm, and crown wheel core.
The way I think I understand it is that I have a cal 825 movement based on the 815. If I am correct (and I'm looking for correction) I should be able to use parts for either 825 or 815 with the exception of parts for the calendar mechanism?
I've hit the usual suspects: Ofrei, Cas-ker, Jules Borel, etc. Are there better ways or better sources to locate parts for this movement?
