PowerWatch is equipped with a MATRIX-powered thermoelectric engine that is one-of-a-kind. It allows PowerWatch to be powered by the body heat of its wearer. This maximizes activity and provides more flexibility when it comes to smartwatches. It’s the world’s first smartwatch to be powered like this, and it NEVER requires charging. You can always be on the move and never have to worry about charging up. No other smartwatch can do that.
