Finiky Automatic Movements?

[HammerTime]

Has anyone ever had an automatic movement watch (in my case an Asian 7750) that winds fine manually and while being worn but won't wind on a watch winder?

I have auto GENS (Omega and Panerai) and some reps (mostly Panerai) that I put on my winders and two of the Reps (both Asian 7750) don't seem to get a good wind on the winder. All the GENS (swiss 7750) and all the other reps (which also have Asian 7750 or Japanese 21J) seem to wind fine.

Any thoughts?

I would say that either your winders are not providing sufficient 'wind' for the watches (refer to your winder's manual or the watch company's support staff for minimum winding requirements) or there is a problem with some of the watches rotors (the half-moon shaped weights that you can see spinning through clear-back cases). The rotors may be hanging up on something inside the case or their bearings are dry/defective. Assuming it is not a winder issue, you will need to have a watchmaker inspect the watches.
