Is my watch water resistant?

Meaning IP 68 certification for water resistance
IP = protection against ingress of water
6 = Dust-tight
8 = Withstands immersion in water up to 1 m deep (normally for 30 minutes).

While a smartwatch with IP68 can be worn while jogging in the rain or washing hands, and can even be dropped under in a swimming pool or other watercourses, IP ratings do not take water pressure into account. Therefore, IP ratings are not an indicator of whether a device can be used in water activities such as swimming or diving.

Furthermore water resistance is not a permanent condition and may degrade over time. We recommend not exposing the watch to chemicals such as soaps, shampoos, sunscreen oils, conditioners, lotions and perfumes. In addition, water resistance may be affected by the following:
o Impacting the watch (e.g. dropping it).
o Showering with very fast water
o All kinds of acidic food
o Hot, humid places (e.g. sauna)
