The watch is chunky but still looks and feels great on tiny wrists! The circuit sandwich becomes the face of the watch, and you'll use a tactile switch to make a mode selector. The watch has timekeeping (one LED for hours and one for minutes), GPS navigation (customize your waypoint in the provided Arduino sketch), and compass modes.
