But I agree about a 42mm Rolex wearing bigger than its size. My wrist measures just over 7"... so relatively average. I have a Milgauss and a YM 16622, which are both 40mm. They are perfect size for my wrist, but I can't imagine going bigger. I have tried on other 40mm watches that don't seem as big. So, a 42mm Rolex would be too big for me. But as far as aesthetics of the Explorer, I really like it. But I would think one would need a 7.5"+ wrist, or just like really big clunky watches to pull this off.
Cheers
