The mid-budget Kospet brand smartwatches are a strong and dependable wrist accessory for challenging conditions, including extended hikes and extreme sports. In the brand's lineup, this model is the senior solution and is positioned as a versatile device for active lifestyle enthusiasts, diving, swimming, triathlon fans, etc. The case is made of high-quality steel, with overall strength and reliability confirmed by compliance with several standards, including MIL-STD-810 and SGS.

They are ready for underwater exploration, thanks to excellent water resistance (10 ATM and IP69K ratings), the presence of a depth gauge, and support for three diving modes. The Kospet Tank M4 smartwatches feature a large 1.96-inch AMOLED display with high detail and brightness (502x410 pixels and 1000 nits respectively), as well as Gorilla Glass 3 protective glass. They have a light sensor that automatically adjusts screen settings.

The model's strong points include an extended set of sensors and advanced navigation, including a Dual GPS module, track guidance feature, map support, and the ability to import routes. Additionally, there's an impressive array of 160 sports modes, Bluetooth calls, and a good memory capacity for music (32 GB). Usual metrics are enhanced with environmental temperature measurement, stress level determination, and blood oxygen level. The 400 mAh battery is expected to offer from 5 to 14 days of autonomy, depending on active or regular use.
