The Black Bays and especially the Black Bay 58 are really nice watches. The Mt5402 movement seems to be exceptional and I do prefer the smaller and slimmer watch dimensions. Nevertheless despite the positives of the Black Bay 58, put me down in the Rolex camp - not a big fan of the snow flake hands....the hour hand reminds me more of a primitive sort of hammer rather than a snow flake. I like the quality, the beauty and the sturdiness of a Rolex Submariner.
I am thinking now of alternating between my Explorer and an Submariner. Thats my story!
