I can't wear the gen Rolex from my father-in-law at 39mm. Far too small, looks like you are wearing a button on your wrist. Some might say better than wearing a dinner plate but I am a big pilot kinda guy..
Definitely a big yes! I lost weight and my wrists slimmed down, and now all I can wear are smaller watches. Anything larger than 40mm in diameter & 47mm lug to lug looks too big.
