ABSTRACT:
A digital alarm timepiece including a time standard for generating a time standard signal, a divider for dividing the time standard signal and developing a repetitive output signal, and a counter receptive of the divider output signal for counting the same and for developing a count representative of time and date. A date-second switching circuit cooperates with the counter for switching between a count representative of seconds and a count representative of date. A plurality of memory circuits define respective channels and each stores a time signal representative of a time. A display responds to the contents of the counter and to the time signals for displaying a time corresponding thereto. A channel selecting switch applies a selected one of the time signals stored in one of the memories or the counts switched by the date-second switching circuit for displaying a selected time or date or seconds. A coincidence circuit compares the count developed by the counter with the time signals stored in the memories and develops an output signal when the count and one of the time signals coincide. An alarm responds to the coincidence circuit output signal for developing an alarm signal. The channel selecting circuit, the date-second switching circuit, and the alarm are controlled by a plurality of manually operable switches.
