Question about movement on 1950s Longines

Hello everyone, I picked up a Longines wristwatch from the 1950s (cal. 6922), service history unknown. When winding it up, I feel a fair amount of 'skipping' in the mechanism and there is a clicking sound when this happens. I assume something is getting disengaged when it is wound. I can get it fully wound, but worry this could involve stripping of gears or threads. The crown is signed, but I cannot be sure it's correct/original.

Can anyone comment on what might be the problem here? I imagine this is kind of a general problem and not really specific to this movement; I'm just providing the info for context. The watch was fairly inexpensive (~$300) and I'm trying to gage whether or not it's worth pursuing a repair, or attempt to return. Thanks

By the way, if this sort of question is better suited for another section, please do let me know.

That's fair. In retrospect, I see this is not really a well-posed inquiry. Thanks again
