Abstract
An analogue electronic alarm timepiece has a dial on which time is displayed by the usual hour, minute and second hands. The time for which the alarm is set is displayed digitally in an aperture provided in the dial. The digital display of the alarm time is effected by means of a rotatable hour wheel having hour indicia thereon and a rotatable minute wheel having minute indicia. The hour wheel and minute wheel are selectively rotatable by manual operation of an external stem. The hour wheel and minute wheel are magnetically and electronically coupled with alarm time memory means. Time counting means is electronically connected with a dividing circuit which divides a standard signal produced by an oscillator and to which a motor for driving the hands is also connected. The alarm is activated by a coincidence circuit when the time of the time counting means coincides with the time for which the alarm time memory means is set. Means is provided for synchronizing the time counting circuit with the hands.
