No company claims theirs products are waterproof, that's a layman's term. A Rolex Deep Sea Dweller is "water resistant" too, not waterproof, but you expect that you can use it down to the rated 3900 m. The people here make all kinds of excuses for Apple, getting hung up on terminology, but this advertising is BS and I hope they get called out on it at some point in Canada or Europe.
No, because the federal trade commission regulates its illegal to claim anything as waterproof when involving Waterproof watches.
