ABSTRACT:
An arrangement for correcting an electronic timepiece comprises a normally reset flip-flop that holds, when set, a "second" counter in a reset state. When a first switch is closed after being released, the timepiece cyclically gives a normal, a "minute," and an "hour" indication. While a "minute" indication is given, a second switch is closed to set the flip-flop and advance a "minute" counter. When the second switch is released after the "minute" indication is advanced to a correct time, the "second" and "minute" counter are kept still. When the first switch is closed at the correct time after being preliminarily released, the flip-flop is reset to restart the watch with correct "minute" and "second" indications. The arrangement enables the correction to be carried out once again. While given, an "hour" indication is corrected by the second switch. If desired, correction of the "minute" and "second" indications and/or the "hour" indication may be omitted and a "day" or a longer-unit indication may be corrected by the second switch.
