Today I received the Mk2 GBR watch... gotta say, I never thought Oris could outdo the dial on the Mk1 in a dive watch... they did... I still prefer the Mk1 in general, but the Mk2 really exceeded my expectations. both watches feel solid. but I think the rotating bezel on the Mk2 feels cheap and the clicks arent as smooth as the Mk1. I find the time setting a little disappointing on the Mk2... requires more turns to get the hands moving than the Mk1.
