Can't speak for anyone else but what I want is for Apple to fix my watch if it gets fried in the shower. Not for them to tell me "Yeah, it's waterproof but we told you not to do that" and be stuck with a $300 paperweight.
The Apple Watch is water resistant, not Water Proof. Tim Cook said when the Watch was released, he showered with his on. It can get wet, but I would not submerge the Watch. Even though, some swim with theirs and have had zero issues. I still would not recommend it.
