ABSTRACT:
An electronic alarm timepiece has a rotatable ring producing clicks when the ring is rotated from a first position aligned with one of the hands to a second position at which the alarm will be actuated when the hand reaches such position. The clicks are transmitted to the electronic timepiece logic through the same piezoelectric transducer which produces the alarm sound. The logic means actuates the alarm after an elapsed time which is proportional to the number of clicks counted when the ring is rotated.
