I used a screw extractor when the same thing happened on my Sawtooth. I would send it to you but it has disappeared (meaning I can't remember where I laid it down). I will see if I can purchase another and send it to you.

The one I used is a #1 fine thread (there is a #1 course thread too but you want the fine thread).
No drilling is necessary especially with the hex screw.
I'll see if I can source one tommorrow.
The epoxy idea MIGHT work but I'm sceptical (no offence to anyone). I've tried that with limited success. If you try it, mask off the whole watch as a goopy nightmare is a definite possibility.
