Raised markers that allow you to feel the time by touch: a triangular marker for twelve, elongated line segments for three, six, and nine, and shorter line segments for the other markers. Two magnetized ball bearings travel around the watch face in separate, recessed tracks: one track around the center of the watch face for the minute, and one track around the outside edge of the watch face for the hour.
