Odd Ball Minimalist Watch
No hands, numbers, markers, or LEDs -- just a free-rolling tiny ball. So how does it tell time? Not very accurately. As you walk, the ball rolls around the watch face, then, when you bring your arm into a horizontal position, a magnet pulls the orb into place to indicate the time. As there is only one ball, it has to indicate both hours and minutes. This is a very unusual timepiece. If you're into minimalism, not hung up on the exact time, and have a steady hand, this could be for you.
