Selfishly, what I'm waiting on is a blue Pelagos (same dimensions as currently) but in the FXD blue. I have my name down for both the 39mm Pelagos and the FXD, but I've decided I'll be turning both down as slightly too small (39mm) and too light (FXD). This is me with smaller-than-average wrist (6.75") but my preference is 40-42mm.
Black Bay has always been a turn-off for me as too thick (slab-like), the 58 being a much better fit. So, a slimmer BB would work for me.
