Abstract

PURPOSE: To eliminate the errors at the starting by driving the step motor in excess enough to reduce the backlash when the watch is started upon the end of the pointer adjustment by means of a device for detecting the rotation provided in the pointer adjusting mechanism.
CONSTITUTION: When a stem 8 is depressed, a latch 13 gets in contact with a resetting contact spring 17 to halt the drive output to the step motor 4. Under such a condition, with the turning of the stem 8, a day back wheel 16 supported with a slot 18 gets in contact with either a contact spring 19 or 20 depending on the turning direction thereof to detect the direction for correction while the pointer 7 is turned. As the stem is turned to the normal position upon the completion of the pointer correction, the step motor is driven interrupting by frequency required for reducing the backlash before the pointer is driven if the correction of the pointer is made in the direction of the watch advances.
