PowerWatch 2
Matrix Industries’ PowerWatch 2 smartwatch never needs to be charged. It uses your body heat and sunlight to generate power. Unlike its predecessors, it has a color LCD screen, GPS navigation, 656 ft water resistance, a heart rate sensor, and phone notifications.
Crowdfunded projects pose a degree of risk for buyers, so be sure to do your research and fully read the seller's detailed description and production plans before plunking down your hard-earned money.
