• 5ATM waterproof rating (equivalent to 50 meters underwater depth), supports wearing in swimming pools, shallow swimming and other shallow water activities, but not suitable for hot showers, saunas and diving, and needs to avoid direct impact of high-speed water flow during water sports; after use in seawater, it should be rinsed slowly with clean water in time. Leather/metal/woven straps need to be dried in time after contact with water (avoid exposure to the sun or high temperature drying). The waterproof function is not permanent and may weaken over time. For specific product waterproof scenarios, please refer to the waterproof level description for Xiaomi Watch Band.
• The charging time test data comes for Xiaomi laboratory. In actual use, the charging time is related to various factors such as ambient temperature and battery life, and may differ from laboratory data.
