構。[Scope of Claim for Utility Model Registration] (1) A winding stem attached to the main plate and positioned at least at a normal hand movement position and a pointer adjustment position, and a dial wheel that is linked to the rotation of the winding stem at the pointer adjustment position of the winding stem. and a pointer display wheel train consisting of a day wheel, a minute wheel with a minute hand, and an hour wheel with an hour hand; A third wheel rotatably supports a handle on the gear side that meshes with the pinion of the wheel, and a shaft support that pivotally supports the handle on the gear side of the third wheel. A third wheel release lever disposed on the main plate, a rigid part positioned and fixed to the main plate, a winding stem engaging part that engages with the tip of the winding stem, and a winding stem engaging part that follows the movement of the winding stem in the axial direction. The actuating lever consists of a spring part that is displaced by the movement of the needle, and a spring tip part that engages with the third wheel release lever at the tip of the spring part, and moves the winding stem of the external operating member from the normal hand movement position to the pointer correction position. In conjunction with the pulling out, the third wheel release lever rotates, and the gear side of the third wheel, which can swing, is rotated to the 4th position.
A pointer correction mechanism for a wristwatch, characterized in that it is tilted away from the number wheel to disengage the third gear and the fourth pinion. (2) A recess is provided on the third pinion side so that the bearing on the pinion side of the third wheel is at approximately the same cross-sectional height position as the gear of the minute wheel that meshes with the third pinion, and 2. The pointer correction mechanism for a wristwatch according to claim 1, further comprising a shaft portion for pivotally supporting the third pinion recessed portion on the main plate side. (3) A feature of the present invention is that the release regulating portion of the third wheel release lever that receives the handle shoulder on the gear side of the third wheel is provided only on one side opposite to the fourth wheel with respect to the axis of the third wheel. A pointer correction mechanism for a wristwatch according to claim 1.
