Wow, one millimeter is so noticeable in a side by side. And damn, people who decide on odd width lugs should be fired. I've just had to cross the Black Bay off my list. Unless the bracelet is very, very comfortable.
Does the Pelagos look bigger on the wrist than the Sub? I really like them, but I'm not sure if I can go down to a 42mm dive watch (the MM300 I wear now has some really weird measurements, a 44mm case, but only a 42mm bezel, so it wears small for 44, but large for 42).
