I just serviced a 2804-2 which had the problem that when I wound the watch every once in awhile it "slipped". After some advice from a watchmaker it seemed it was a problem with the winding pinion (clutch) and the sliding pinion - their teeth were worn.
So I changed them with a set from a 2842 (from a swatch auto). Under the 15x loupe they seemed identical. Also, it solved the problem, there is no more slippage.
I presented the above because I want to ask your opinion for the problem that I have now:
When I wind the watch the crown turns quite hard IMO. It happens in both directions (both when winding the mainspring and when turning the crown back - when the sliding pinion slips over the breguet teeth on the winding pinion). The problem is also present with the crown wheel off (the one that engages the ratchet wheel). I put silicone grease on the case tube - it didn't help.
Do you think the crown is the problem - namely the rubber gasket in the crown - maybe it got old and hardened? Or do you think it's the pinions that I replaced?
Thank you,
Bogdan
