Dbane883, did you ever install this bezel assembly on a watch?
i purchased an aftermarket bezel set but the nylon ring that inserts in the slot on the bottom of the bezel is not T-shaped as you described on the one that cane with your gen set.
also as you last described I believe the sequence of assembly is:
1. Crystal with gasket over rehaut.
2. Clamping ring pressed over crystal gasket.
3. Springs, bearings, clicker.
4. Bezel, with bezel nylon fastening ring installed in the bezel groove, pressed over clamping ring.
5. Bezel insert ring placed on bezel.
6. Bezel insert pressed into bezel.
Dont think there is any nylon clip holding insert into bezel. Insert simply press fits into bezel.
