The water resistance level of the Xiaomi Watch 2 is 5ATM, suitable for shallow water activities such as swimming in a pool or at the beach. It is not suitable for high humidity and high-temperature environments like saunas and hot springs, nor for high-speed water activities such as diving, jumping into water, surfing, and deep-water activities.
Note:
The 50m water resistance performance means the watch can withstand pressure equivalent to 50m underwater in a static state. The pressure resistance value is not obtained underwater but is calculated based on air pressure. The water resistance function is not permanently effective and it will weaken over time.
