ABSTRACT:
A handless timepiece such as a clock or watch having a time indicator mounted on a driven belt of finite length driven by two rolls and wherein the time symbols are arranged in a preset sequence of the belt, and are caused to pass between these rolls in front of an indicator window, and wherein the belt drive is designed so that the belt is alternatively taken up from one roll to the next. The time symbol sequence on the minute belt is "00 59 01 58 02 57 03 . . . 33 27 32 28 31 29 30" and the time symbol sequence on the hour belt is "0 23 1 22 2 21 3 . . . 15 9 14 10 13 11 12", and wherein every second symbol appears in the indicator window. The present handless clock or watch avoids rewind of the belt and the concomitant lost time ocasioned by such rewind.
