Dear friends, I'm trying to order the genuine crystal for my Bumper. Cannot find the right number for it. Back cover shows: F6212-W208174 Caliber 342. According to the serial number, the production date is around 1950-1951. I measured the crystal without bezel: Outer diam. ~29.2 mm, inner diam. ~27.5, outer height ~5.0 mm Bezel loading diameter for crystal is ~29.0 mm. Does anyone has an idea that PZ, PN or PX could it be? Thank you! Vad
This is an American, Wadsworth case. These were produced in the USA and then fitted with an Omega dial and movement. So the original crystal would not have been an Omega part but a generic item used by Wadsworth. All you really need is a generic crystal with the correct diameter and height.
