摘要： PROBLEM TO BE SOLVED: To provide a mechanism which can synchronize a minute hand and a second hand, in a clock which has a mechanism having at least the minute hand and the second hand, and matching the minute hand by a movement.
SOLUTION: The mechanism in which the minute hand of the movement is coincided includes a winding stem which can be adjusted to an axial direction between a normal position and an adjusting position. The winding stem is connected with back wheel groups of a day of the movement so as to adjust the minute hand by the rotation of the winding stem when the winding stem is in the adjusting position. Furthermore, the winding stem collaborates with a return-to-zero mechanism. The return-to-zero mechanism moves the second hand to a zero position when the winding stem moves to the adjusting position. During the winding stem is located at the adjusting position, the return-to-zero mechanism stops the second hand at the zero position. When the winding stem is returned to the normal position, the return-to-zero mechanism releases the second hand again. By this, the back wheel groups of the day of the movement have stop mechanisms. This stop mechanism can be stopped at sixty stopping positions. Therefore, by rotating the winding stem at the adjusting position, the minute hand can be adjusted to the head of a certain minute scale between sixty positions of the minute hand.
