All-purpose smartwatch with 15-day battery life
The popular Kospet Tank M4 smartwatch has a new version. This one features a round 3.63 cm AMOLED display (1.43 inches), a resolution of 466 × 466 pixels, and a brightness of 1,000 nits. It's available on Amazon for around 158 euros.
The new version brings advanced GNSS support with a dual-band receiver and six navigation systems, enabling fast and accurate positioning. Users can also download free maps to the watch for offline use.
The watch includes optical sensors for measuring heart rate and oxygen saturation, while ECG is not supported. There is also sleep tracking. There is a built-in speaker and microphone, which allows for Bluetooth hands-free calling, and the watch also has a walkie-talkie function with a range of up to 40 meters.
Battery life is up to 15 days in normal use or up to 22 hours in GPS mode. The watch is water resistant to 10 ATM, which means it can withstand pressure up to 100 meters deep. Therefore, it is not surprising that the novelty is also suitable for swimming, but not necessarily for diving.
