Actually there are three strobe LED’s in a pod, on an arm over the face. The clock hands are all really just one line on the face, spinning at 60 revolutions per second. Since each LED has a different color, illumination diameter and blink times, the observer’s persistence of vision causes hour, minute and second hands to be seen.

By slowing the strobe of the second hand LED to just less than 60 flashes per second, the second hand appears to move smoothly, relative to the numbered, fixed outer ring. Being a gyroscope, means the watch can be read at almost any angle. Also a bubble watch on a chain and a gyro-watch ring are in development.
