Rogbid Tank M5: New AMOLED smartwatch evokes suspicion with promises of extensive sensor technology and telephony features

Rogbid has a new smartwatch in its range, the Rogbid M5, which is not yet officially available outside China. International buyers therefore have to turn to a direct import, but shipping is not guaranteed for all countries.

The watch has a 1.43-inch AMOLED with a resolution of 466 x 466 which promises high sharpness. The smartwatch is also partially made of zinc alloy, which is said to guarantee a high level of durability. The range of functions is extensive, including the possibility of controlling music playback on a paired smartphone. There is also a microphone and loudspeaker, so phonecalls can also be made directly on the smartwatch.

Rogbid advertises a number of various health features. In the best case scenario, the heart rate and oxygen saturation measurements may be accurate, but we believe that the precise monitoring of other parameters - if they are actually measured at all - is almost impossible. For example, it should be possible to measure blood pressure and blood sugar levels purely optically, which would represent an absolute breakthrough in optical sensor technology and would pose considerable problems for manufacturers of corresponding medical products.

The analysis of sleep quality and sleep duration is relatively realistic, which can be carried out by monitoring movements recorded during sleep. Stress levels should also be measurable. A 400 mAh battery is installed in the approximately 12 millimeter thick watch. As usual, charging takes place via a magnetic plug.
