I have a beater gold Rolex (it was my grandmothers) and Rolex last serviced it almost ten years ago saying that they could not guarantee it would keep on going. And yet, here we are. It could probably withstand a hurricane. Same with an old GMT. Sadly, I am careless and clumsy with watches, but prefer the aesthetics of a Cartier, IWC, JLC, or other. My two tone Cartier tank (which seems more sturdy than a BB) is wonky when briefly submerged (dishes). . . My stainless pasha C is a bit better So long as the button is screwed in. I used to have a santos that could take more of a beating, but it really showed wear and tear. So, no I wouldn’t go swimming with a BB regularly, but YMMV. I sadly missed my chance at a pink gold la Dona Cartier (DH intensely disliked it at the time) and now they are discontinued, so I’m searching for one. But, if I find one, it won’t even go with me into the shower. I don’t think Cartier’s are meant to get wet.
