Choose one or the other; so many anti Tudor individuals on the forum that they'd rather choose a watch which is useless for the described purpose than a Tudor. This is a true Social Experiment. My thought is that most who buy Rolex don't have a clue as how they can perform. Or maybe I'm just cynical.
