Funny, because I am not a big guy. (5’7”, 150 lbs.) I do have a 7” wrist, and quite flat, so I seem to do OK with watches much bigger than this: Portugieser Perpetual Calendar, GO Senator Cosmopolite, A & S Time Pyramid (all +/-44 mm). A full-size Radiomir does test my limits, though! (Straight lugs an all…) ;-)
