I don't have it now (sold it), but when I had an Omega Seamaster diver (2255.80 with the ETA 2892A2/Omega 1120), it was a veritable tank, and I wasn't afraid to pretty much wear it anywhere and in anything. I think that's why we like 'em so much because they're built like tanks! (True also for Rolex Sub, JLC, etc.)
You're a lucky man! =:^D
