Claims

[Scope of Claim for Utility Model Registration] A winding stem mounted on the main plate and positioned at at least two positions, a normal hand movement position and a pointer adjustment position, and a dial that is linked to the rotation of the winding stem at the pointer adjustment position of the winding stem. A pointer display wheel train consisting of a wheel, a day wheel, a minute wheel with a minute hand, and an hour wheel with an hour hand; a third wheel that is rotatably supported; a third wheel engaging/removing lever having a hole for pivotally supporting one end of the third wheel and a guide hole that engages with a guide boss provided on the base plate; , a rigid body portion that is positioned and fixed to the main plate; a winding stem engaging portion that engages with the winding stem tip; a spring portion that is displaced following the axial movement of the winding stem; It is composed of an actuation lever consisting of a spring tip that engages with a third wheel release lever, and the spring part of the actuation lever is flexed in conjunction with the movement of the winding stem from the pointer correction position to the normal hand movement position. When the third wheel engages and engages with the minute hand, the third wheel engages and disengages the third wheel in the direction of the minute hand, and the third wheel engages with the minute hand. The guide hole of the third wheel engagement lever is an irregularly shaped hole with respect to the guide shaft that restricts the swing of the third wheel engagement lever provided on the main plate so that it can move in both tangential directions with respect to the gear. A watch pointer correction mechanism characterized by:
