The Black Bay GMT wears almost like any other Black Bay. It’s slightly chunky (in a good way), with tall polished flanks and a squarish profile that wears really well. When I say slightly, I’m eluding to one small change to the case shape link that Tudor appears to have debuted with the Black Bay GMT. The change is that of a bevel on the underside of the case that removes the hard edge where the case meets your wrist (see below).
