Its 1.43-inch AMOLED display integrated with an ambient light sensor delivers sharp clarity in multiple lighting environments. Certified by SGS and tested to pass 20 U.S. MIL-STD-810H standards, the smartwatch is indeed crafted for real-world extremes — on city streets or remote trails alike.

Unleash Your Athletic Potential

Jump into action with KOSPET TANK T4 and switch up your sports performance with a choice of 23 ApexMotion sports modes and 160 freestyle training modes. While you are running on the trail, sliding down the slope, or striving for the mountaintop, the smartwatch provides you with in-depth metrics and post-workout insights to help you train smarter, not just header.

Every Move Does Count

Whether you are pushing through intense sets or making sharp turns, KOSPET TANK T4 can keep up with your movements with its built-in 6-axis gyroscope, which measures changes in your orientation, acceleration forces, and speed, providing a clearer picture of your body’s responses during critical moments.

Run with Precision,
Pace with Direction

From urban running with tall buildings to trail running through the woods, KOSPET TANK T4 tracks your movement with outstanding accuracy, thanks to its industry-leading dual-band six-system GNSS. By downloading offline maps and selecting the target route or location point, you can run your favourite routes or even along unfamiliar paths.

OPDR Algorithm—It’s All About Accuracy

Empowered by the advanced OPDR algorithm, KOSPET TANK T4 serves to record a dynamic activity trajectory when GPS signals are weak or unavailable during outdoor workouts, such as under bridges, so you can tune into your performance anytime, anywhere.
