The KOSPET TANK M3 Smart Watch is a rugged smartwatch designed for everyday health tracking, fitness, outdoor activities, and long-term use. It features a 1.96-inch HD AMOLED Always-On Display with a 410 × 502 resolution, 331 PPI, and up to 1,000 nits peak brightness, providing clear visibility even in bright outdoor conditions. The display is protected by Corning Gorilla Glass 3.
The TANK M3 is built with a rugged design and has passed 15 MIL-STD-810H certifications for durability. It also features 5ATM and IP69K water resistance, making it suitable for everyday outdoor use and water-related activities under the manufacturer’s specified conditions.
For fitness tracking, the watch supports more than 170 sports modes and can automatically recognize six selected activities. It also provides continuous monitoring of heart rate, blood oxygen, sleep, and stress, with additional wellness functions available through the KOSPET FIT app.
The TANK M3 supports Bluetooth calling, app notifications, SMS reminders, music control, and remote camera shutter functions. It uses the ATS3085L processor and a 480mAh battery, providing up to 15 days of typical use, up to 8 days of heavy use, and more than 50 days of standby according to KOSPET’s published specifications.
Unlike the TANK M3 Ultra, the standard M3 does not include built-in GPS, a barometer, or a compass; KOSPET specifically identifies these as additional features of the M3 Ultra.
