Do share.
Gen compared to this one. Maybe it's just an pic angle so don't kill me.
Left gap near 10 is much smaller and krooked,
30 touching inner lip.
40 much closer to lip than the gen one.
Nope, that's a gen insert.
tripdog with all the gen parts offered lately, I wondered too about how to know if a crystal, bezel or insert is gen. If it is sealed in a blister, that I understand ....I even saw a fake blister when visiting my watchsmith once..the seller used gen blister pics and send a selfprinted one but I think this is a exception
