Kospet Tank M3 Ultra

Rectangular smartwatches from the Kospet brand are a mid-budget solution for everyday use and/or challenging conditions. The model features a steel casing with IP69K water resistance, allowing immersion underwater (also suitable for swimming with a profile fitness mode). Durability and shock resistance are confirmed by MIL-STD-810H certification: it's claimed that 15 tests of this American standard were conducted, plus another 28 proprietary tests.

The Kospet Tank M3 Ultra smartwatch is equipped with a large (1.96-inch diagonal) AMOLED screen with brightness up to 1000 nits and a resolution of 502x410 pixels. The display is protected from damage and scratches by Gorilla Glass 3. Strengths of the model include a built-in microphone and speaker (for receiving calls from a smartphone), an advanced dual-band navigation module with track guidance function, as well as a compass and additional sensors, including an altimeter and barometer. For sports enthusiasts, it offers 170 fitness modes with automatic recognition of 6 types of typical workouts, such as running.

The set of metrics isn't limited to 24/7 heart rate monitoring but also includes blood pressure measurement (tonometer) and oxygen saturation, sleep tracking, and the capability to maintain a women's calendar. Powering it all is a 470 mAh lithium-ion battery with a proprietary magnetic charging cable. In standard modes, autonomy ranges from 12 to 15 days, while with active use, it lasts around 5 days, including with the Always-On Display (AOD) function active.
