2. Run of thick crowns!


Recommended Posts

Can someone be a tiebreaker? One watchmaker whom I respect tremendously says the .9 can be retapped to fit a 1.2mm stem. Another watchmaker I respect equally tremendouly says no f'n way. Has anyone actually done this, or tried and failed?

If you have the correct drill, and a 1.20mm tap, you can certainly drill and make new threads for a 1.20mm stem.

I don't have the tooling, so I can't help you out. The crown is the same for the 0.90 or 1.20mm stems, just the hole is different.
