Our smartwatches support both iOS and Android and are compatible with most major smartphone brands, including iPhone, Samsung, Xiaomi, HONOR, and others.
When left idle with no features in use, the watch can last for over a week on a full charge. However, with multiple features enabled—such as Bluetooth calling, message notifications, and health tracking—it may require daily charging, much like the battery usage pattern of a typical smartphone.
IP67 and IP68 are dust- and water-resistance ratings tested under specific conditions. IP67 generally indicates dust-tight protection and temporary water immersion under defined test conditions. . IP68 provides water resistance under conditions specified by the manufacturer. ATM ratings indicate pressure resistance under laboratory conditions; for example, 3 ATM corresponds to approximately 30 metres of static water pressure in a test environment, but it does not mean the watch is suitable for diving to 30 metres. For swimming, please use only models that are explicitly rated for swimming and follow the instructions for that specific model.
