Bought my first PAM plus hand winding question

[Jay15180]

Hi everyone!

I'm glad to finally join the club and start posting in this forum. I recently bought a VSF PAM312 V2 from Ryan and so far I'm loving it. The watch is amazing and looks/feels exactly like the gen I tried on at the AD (minus the obviously awful rep strap). I had a question about the clone P9000 however. I realize most people advise against regularly hand winding an automatic so I've basically avoided it since I received the watch. I noticed however, that the few times I have wound it, the rotor seems to spin with the crown. I don't think this is normally behavior for this watch and I worry that this indicates a lack of lubrication or a need to service the watch. What's the opinion of the board? I'm strongly considering having the movement serviced regardless just to ensure long-term reliability.

Thanks!

happened to my AP Diver couple years ago I ignored it and somehow the issue went away. But you are right it’s the lube. Maybe wear it longer and see if the lube gets distributed evenly?

Yea I searched around a bit and it seems like it a common issue on ETA 2836 movements and often the solution is to lube the reverse wheels. I wasn't sure if this information was applicable to the P9000 so I thought I'd ask. I'm going to have the watchsmith look it over and update the forum when I find out.

This generally indicates poorly lubricated jewels in the auto wind mechanism. Or a bad reversing wheel. Both are easy to remedy. And I believe this movement accepts 7750 parts. But I could be remembering incorrectly.

I wouldn't handwind an automatic if the rotor gives enough power.

I generally avoid handwinding it but I noticed that if i let the power reserve run down it needs a wind or two to get it going again. It seems to “stick” when the movement stops. Also I’ve noticed that it only spins the rotor when the watch is facing down. Perhaps that indicates the oil is moving? Hopefully the watchsmith will have more info.

Actually hand winding is beneficial for timekeeping with any automatic watch that allows handwinding.
If you depend on winding by rotor only then the timekeeping will suffer and it will probably never be fully wound.
This is what they taught us at watchmaking school.
