The balance wheel stops !

[AdrianNOGUES]

Hi    The fitting of a shim is NOT a fix its a diagnostic aid in as much as to slightly increase the end shake of the balance when trying to determine the problem, and once proved on way or the other, then removed and look to rectifying the problem.   I have had watches where the end shake was adjusted by digging a divot in the plate there fore raising the the balance cock and increasing the endshake also had them with shims in to do the same both left as a permanent fix    Not reccomended.   

Okay !

Absolutely. I was surprised to see that this kind of advice given promptly when the practice is generally frowned upon.

Thanks for all the help Jdm, that was just a temporary fix until OP finds the broken pivot. We need advise how to weld it back on.

Well looks like a broken pivot as we can all see, you must have not seated the balance properly before screwing it down which is why it doesn’t look even which was pointed out by John...which is was what I thought to begin with.

One of the problems with your watch is it has a balance jewel protection system. This means the likelihood of you breaking the pivot  through normal use is nearly impossible. But for reassembly  it's a problem in that you have to get the balance pivots through  a relatively tiny hole. the lower one  usually isn't a problem it's the upper one where it's easy to get it off to the side  it might even still spin to some degree but tightening  the bridge screw down  very bad if it's not where it's supposed to be.. I thought for the future  just remove the entire upper jewel assembly which are going to have to do to lubricated anyway. Then you can see that your pivot is where it's supposed to be  before you tighten the bridge screw down..

Ok thank you very much, I haven't made it yet but i'm going to try this without making a mess (like loosing the thing on the jewel of the cock)
