Abstract

PURPOSE: To shorten the time for correcting a digital indication type electronic wrist watch by correcting the hour and minute digit corrections in up and down directions.
CONSTITUTION: A selection button 5 is depressed to input a pulse c to a selector circuit 13 to select one digit from the hour and minute indication digits 1W4. Then, a direction selection button 6 and a count button 7 are depressed to input pulses a, b into a correcting circuit to select the up or down correcting digit direction so as to up or down count it. The up or down counter employs a ten-hour digit ternary counter 14, an hour digit decimal counter 18, a ten-minute digit sexanary counter and a minute digit decimal counter 26. Since the up and down directions are provided in the counter, it can reduce the time for correcting the electronic wrist watch.
