Its high-quality stainless-steel body and Corning® Gorilla® Glass 3 screen provide a substantial, premium construction suitable for active environments.
Military-grade testing does not make the watch indestructible. Severe impacts, crushing, misuse, chemicals and exposure beyond its stated limits may still cause damage.

Six supported activities can be recognised automatically, helping capture common workouts when enabled through the watch settings.

Strength, rowing, elliptical and indoor exercise.
Pool metrics including laps, strokes, pace and SWOLF.
❤️ Daily Health and Recovery Insights
The VP60A2 optical sensor supports heart-rate, blood-oxygen, sleep and stress trend monitoring throughout your daily routine.
Sleep information may include light, deep and REM stages, while stress information and guided breathing functions can support more mindful recovery habits.
Health, blood-oxygen, stress, sleep, heart-rate and activity readings are intended for general wellness and recreational purposes only. This watch is not a medical device.

Once paired with a compatible smartphone, the TANK M3 Ultra supports Bluetooth calling through its built-in microphone and speaker.
Supported SMS and application notifications can appear on the display, helping you remain informed without repeatedly checking your phone.
Additional connected functions may include music control, remote camera shutter, weather information, alarms and phone-finding tools.
Power for Longer Adventures
470mAh Cobalt Battery
The 470mAh rechargeable cobalt battery provides extended power across everyday, fitness and outdoor use without requiring daily charging.
Battery performance varies according to GPS use, always-on display, Bluetooth calls, brightness, notifications, health monitoring, workout duration, connection quality, temperature, settings and battery age.
