Your "lapping" of the crystal with multiple grits of "sandpaper" works well. It reminded me of the few times I talked to the guys in the Canopy Shop where I worked. They went up to at least 20,000 grit, but I have no idea what the abrasive on the "paper" really was. Did you use "regular" sandpaper like you can get from auto-body paint supply stores? I know their paper goes up to and probably higher than 2,000 grit. I ask because your crystal material is a lot harder than bullet-proof Lexan or auto-bodywork materials/primers/paints.

Hi Bob. Yes its automotive sandpaper. Its all the grits I had at the time. I may get some fine diamond paster later but for now I’m pretty happy with the results.

Doesnt that scratch the bezel if you sand it while the crystal is in the watch ?

[@LetsRogerThat]

In my case it did not.
