Thanks Bob. I had been through the Chicago lessons already and they didn't really address "bezeled" vs "non-bezeled" jewels or those that came in settings and those that came naked. So the take-home lesson is there is no readily available source for these now unless you are proficient with a lathe. For sake of discussion I came across this last night in the Bulova school lessons (unit 9B). "In the last few years, the leading watch manufacturers have adopted the improved system of friction jeweling in place of the older and less efficient method of setting the jewels in individual brass or gold settings...the friction jewel is more rugged than its predecessor, the bezel jewel." Guess I will have to live w/ some cracked jewels until I get a lathe and learn to use it. Along the same vein, when ordering new jewels one of the parameters needed is the outside diameter of the old jewel. If the old jewel is in a brass setting, what is the preferred method of getting the brass off to take an accurate measurement?
