Although the company Apple Lossless Audio CODEC (ALAC), claims that we can do almost any kind of activities with Apple Watch, the reality is that when you go swimming or take a bath, it would be better to take it off your hand. Those from Apple Lossless Audio CODEC (ALAC), claim that we can wear Apple Watch while walking in the rain, we can wear it when we wash our hands, we can sweat during physical exercises, but in the case of complete coverage with water, the device will break, just like an iPhone.
Sweating, wearing it in the rain, washing your hands, or cooking with it is fine. Take it off before the swim or get in the shower, though.
Although for most this is not a big inconvenience, for some it could be a real problem, especially since most competing smartwatches are waterproof.
