Is Apple Watch waterproof

Hello ~ Take a look here:

About Apple Watch water resistance - Apple Support

It is water resistant. It is fine for swimming, etc. It should be fine in the shower, but try to avoid putting it a position where water is jetting directly into the speaker slits or the crown.

Support page quote;

Showering with Apple Watch Series 2 and newer is ok, but we recommend not exposing Apple Watch to soaps, shampoos, conditioners, lotions, and perfumes as they can negatively affect water seals and acoustic membranes. Apple Watch should be cleaned with fresh water and dried with a lint free-cloth if it comes in contact with anything other than fresh water.
