There is some great info in here.
I just found out that my friend's son actually has a watch company that is putting together some good looking and seemingly qualityish pieces. I'd be curious as to the take of you true horological junkies...

It's not what I'd consider a dive watch, but my wife just got me a Breguet Marine (100atm) for my last birthday. With a screw-in crown and a stainless steel bracelet, it's hugely versatile. I'd have no qualms wearing it with a snorkel, jeans, or a suit. The best part to me is that nearly no one recognizes it for what it is and those that do are watch people who enjoy the non-ubiquitous selection (vs say a Sub).
