Update: while I still remember.
Bezel action hasn’t been great.
Way too stiff.
Tried using half a bezel washer and it was ok but bezel was a bit loose and click action wasn’t consistent
I used double sided tape and stuck the washer to the underside of a huge socket, sanded it down from about 0.22mm to 0.19 mm
Much better but the click feeling wasn’t nice and sharp like my TC watches.
Not sure what a gen is like but I like the louder clicks, so swapped the gen click spring out with a startime one and it’s way nicer.
Tried a startime bezel on the Viet retaining ring and it’s diameter was such that it would easily fall off.
Tried the Viet bezel on a gen retaining ring and would have had to use way too much force to get it to click into place (on the bench, not on the watch yet)
So for the sake of nice clicky action it’s staying with the Viet retaining ring, ST click spring, sanded Viet washer, and Viet bezel.
Maybe I’ll look for a gen bezel to go with the gen retaining ring I have.
