Abstract
An electronic timepiece having a time alarm. The timepiece includes a time counter circuit for developing a progressively increasing count representative of time. A single alarm counter and a repeat alarm counter both store respective counts representative of respective times. The single alarm counter is responsive to a reset signal for clearing the count stored therein. A coincidence detecting circuit compares the respective counts stored in the single and repeat alarm counter circuits with the count developed by the time counting circuit, and develops an output signal when the compared counts coincide. An alarm responds to this output signal to indicate when the time represented by the compared counts coincide. A gate circuit is effective for alternately applying the respective counts stored in the alarm counter circuits to the coincidence detecting circuit to alternately compare the count developed by the time counter circuit with the respective counts stored in the alarm counter circuits. The gate circuit applies the coincidence detecting circuit output signal as a reset signal to reset the single alarm counter circuit when the count developed by the time counting circuit coinc…
