Power is not the limit. We built the T-Rex Dual Solar so it never has to be. When the days stretch longer than expected, when the trail keeps going past where you planned to stop, when there's no outlet for miles, you don't need to change your watch, or worry about charging it. At the center of the experience is the world's first dual sided solar charging system for an AMOLED smartwatch. By capturing solar energy through either the display and an innovative glass ceramic back plate, it continuously supplements battery life throughout extended outdoor adventures, quietly adding charge whenever conditions allow.
