Kospet Tank M3 Ultra

KOSPET TANK M3 Ultra Rugged GPS Smartwatch

A military-grade outdoor watch that delivers specs usually found much further up the price ladder. The TANK M3 Ultra pairs a full stainless steel unibody with a Corning Gorilla-protected AMOLED display, and it’s certified to MIL-STD-810H across 15 military tests plus 28 internal reliability tests covering salt spray, rain, impact, high altitude, temperature and dust.

The 1.96-inch AMOLED runs at 410×502 with 1,000 nits peak brightness and an always-on option, which keeps it legible in direct sun. Underneath, a dual-core setup handles performance and efficiency, with an AI voice assistant that can place calls and reply to messages hands-free — useful while driving or running.

Navigation is the standout. Dual-band L1+L5 GPS works across six satellite systems (GPS, GLONASS, Galileo, BeiDou, QZSS and NavIC) for accurate positioning on remote trails, backed by a built-in compass, barometer and altimeter for field use.

Water resistance is rated 5ATM and IP69K — good for 50m immersion and pool swimming, with a built-in SWOLF swimming index. There are 170+ sports modes with six intelligent activity recognitions, running on an upgraded optical biosensor that tracks heart rate, SpO2, sleep and stress around the clock. Bluetooth calling works through the built-in speaker and microphone.
