Broken Screws In Watch Movements.

[BeyondWorld]

Hey guys, I bought a 1960's omega 120 with a stuck screw in the set lever.

 

Any tips of removing this without replacing the part?

 

First thing I'm going to do is put it in the ultra sonic cleaner to try and sonic it out, but I'm not that optimistic that it'll work.

 

I'm a bit worried about drilling it out, incase the screw thread gets damaged.

 

The only other thing I've heard about is Vissin Screw Extracting Fluid by Bergeon, never used it before and not sure how to either.

I would try this (screw loosening fluid) in combination with the ultrasound:

Oh, I got lucky, the ultra sonic cleaner worked, I used WD-40 as the liquid and it worked nicely.
