my humongous wrist is 6.5ish in. I’m mid build. It’s one of my fav. 42mm is just right for me. I tried on 39.5 and preferred 42. It’s a little more watch for the money. Howver, if It were my daily, I’d go 39.5.
zero issues, since new. It’s a tank, just like many modern O. I don’t abuse my watches, but I don’t baby them either. I go thru my day, doing all the dude stuff, shooting hoops, jogging, playing w Barbie (ahem, with my daughter) with whatever watch I put on in the morning. I made a mistake of removing my watch to play ball in my teen, and never saw it again. My watch stays on me till I come back home. If it fails on me living life, it doesn’t deserve a spot in my box.
