@douginamug WATERPROOF OR WATER RESISTANT ?
Waterproof means different things or there is enough variation in the usage and legality of these two terms.
It seems it's enough to 'displace' a bit of water for example or that it's splashproof to be "waterproof"(to a certain level).
Going under water is usually totally a different thing!
Watches were using these a lot previously.. and people thought they could go under water :) Not so.
So Waterproof and water-resistant can be both thought as the same thing or meaning depending on *who* is saying it and where you see it.
Waterproof - just might mean doesn't easily allow in water (which almost all this electronic are hehe :) )
