I'm not saying that I go diving with any of my watches. But the ones that I have that are waterproof stay on if I'm at the beach or go swimming in the lake.
Just saying I wouldn't have a leather strap on my SKX in the same way that I wouldn't wear a pair of brogues to go jumping through puddles.
I love the look of that but I've never understood leather straps on watches that can go into water. Surely its a bit counter-intuitive?
