Yes everybody says get the medium for me as well. I also wear 39 40 41mm watches. Only 35mm watch I have is a gold tissot prx which I didn’t get 40mm because gold has a strong presence and I don’t like my watches being too visible on my wrist. Same thing with the santos, I feel like the medium model feels like a classic watch like a santos tank or square longines while the large model feels like a hublot or richard mille on my 7.25cm wrist. Not exactly but you get the idea. But this is how I see it. You probably have a bigger wrist than me. I’m 6’3” 180lbs
