PURPOSE:To enable a digital electronic watch to be equipped with many correcting features by providing its stem with normal position, half pulled out position and maximum pulled out position so that a different object of correction can be selected. CONSTITUTION:When a stem is in normal position, a push-pull 18 of a group of correction control gates 40 are all in OFF position and therefore correction is not conducted. When a push-button switch S3 is closed, an indication lighting lamp L is turned on. As the stem is set to half pulled out position, AND circuits 43 and 44 of a group of correction control gates 40 become in ON position so that date and day of the week are selected as objects of corrections. If the stem is set to maximum pulled out position, hour and minute are selected as objects of corrections. When the stem is set back to the half pulled out position from the maximum pulled out position, year and month are selected for corrections. |
