ABSTRACT:
A digital electronic alarm timepiece comprising an oscillator circuit for generating a signal, frequency dividing means, time counting circuit means, alarm time memory counting means, alarm sound signal generating means and a coincidence circuit for activating the alarm sound signal generating means when coincidence occurs between the time of the alarm time memory counting means and the time of the time counting circuit means, has manually operable switching means for activating the alarm sound signal generating means independently of the coincidence circuit. The switching means comprises four individual switches which can be selectively actuated in different combinations to amend the count of the time counting circuit means, to set the time of the alarm time memory counting means and to activate the alarm sound signal generating means.
