The ultimate dive watch is hardly a Rolex. A Rolex is not even the most expensive dive watch. If I were to spend that sort of money for a watch I might go Omega. THE dive watch is the Seiko SKX007. The watch that I have that gets the most attention and even a few random offers to purchase off my wrist is my Citizen Titanium EcoZilla, NLA. My favorite automatics, Seiko products aside, are my Doxa Sub Shark Hunter and my Marathon SAR.
Computers are fine but I still wear a watch. I do not have to interpret a set of numbers, I can just look at the hands and the pip on the bezel to see where I am in my dive, or flying approach or waypoint, or checkpoint in a rally.
I do not like these gigantic, pretentious fashion watches, no matter who made them. Once a watch gets much beyond 42mm +/- case width it no longer functionally augments and compliments my life but gets in the way of it instead.
