Pam 127 having winding skip

[ql224]

Hello everyone, I could really use some advice from the experts on the forum. Im having some trouble with the winding mechanism on my Pam 127.

Basically when I wind the crown, every 3rd or 4th click the click ebauche will slip. I can still wind the watch to full but becomes tedious and im worried that its worsening the problem.

ive checked that all 3 screws are tight on the click ebauche, rachet wheel ebauche, and crown wheel ebauche.

In addition, I visually confirmed that whenever it slipped, it was the click ebauche that skipped.

Thanks for any support from this fine community!

I would have the movement looked at, especially if you've already checked the screws which are normally the cause for the phenomenon and is easily fixable that way. Might be some other problem. But then I am not a watch maker so I cannot comment on the technical aspect of the problem, just what I've been able to glean from searching. Good luck.
