FAQ
What’s the difference between the M3 and the M3 Ultra?
The TANK M3 is built for ultra-long battery life and extreme durability, making it a tough companion for daily wear and outdoor use.
The TANK M3 Ultra goes a step further by adding gps in watch, plus a barometer and compass, making it ideal for users who need advanced navigation and tracking in outdoor adventures.
Who are the TANK M Series best suited for?
It depends on where you are. Orders processed here will take 5-7 business days to arrive. Overseas deliveries can take anywhere from 7-16 days. Delivery details will be provided in your confirmation email.
Does the TANK M Series support third-party fitness apps?
Yes. The TANK M Series works as a strava smartwatch by syncing with the KOSPET FIT App, which also supports Apple Health (iOS) and Google Health Connect (Android) for seamless fitness and health data integration.
Is it comfortable for smaller wrists or for women?
Although it’s a rugged smartwatch, the lightweight silicone strap makes it comfortable for most wrist sizes. For slimmer wrists, we recommend choosing the lighter band option so you can enjoy all-day wear without compromising style or function.
Is the watch really military-grade?
Yes. Both the M3 and the M3 Ultra in the Tank M Series have passed multiple MIL-STD-810H tests for shock, dust, and temperature. As part of a true military style watch line, they’re built tougher than most standard smartwatches.
