Abstract
PURPOSE: To reduce the thickness of the wristwatch by disposing a third wheel within the height in the thickness direction of the movement of the tooth part of a cannon pinion with the minute hand.
CONSTITUTION: The cannon pinion 2b of a center wheel and pinion 2 fitted with the minute hand 13 is loosely fitted to the central shaft 1a studded in the plate and the third wheel and pinion secured with a third wheel 3a are supported by the bearing studded to the plate 1 and the bearing studded to a wheel train bridge 8. And the third wheel 3a is disposed within the height in the thickness direction of the movement of the tooth part 2c of the cannon pinion 2b. Thereby, the thickness of the movement is reduced in the central part of the movement giving a grave influence in the determination of the movement and the reduction in the thickness of the wristwatch may be achieved.
