Now now, you haven't joined the club till you've found a bezel insert...
Seriously though, without the bezel insert that's already mighty fine lookin'!
I noticed that as well. I thought it could've been sunlight, or at most an odd manufacture job from Omega. Otherwise, the bezel looks legit as far as I can tell.
My Watchco Seamaster 300 on an Omega crocodile strap. I found it somewhat surprising that a lot of you have a dive watch on a leather strap.
