*5 ATM water resistance: Xiaomi Watch S1 has a water resistance rating of 5 ATM (50 meters in depth). The rating is based on standard GB/T 30106-2013 and standard ISO 22810:2010. It can be worn in the swimming pool, while swimming near the shore, or during other shallow-water activities. However, It cannot be used in hot showers, sauna, or diving.
