Abstract:
1. A timepiece having indication members mounted on gears forming a gear train to indicate time, and a time correction mechanism operated by an external operating member to transmit an external operating force to an inside of the timepiece, comprising: at least two gears forming the gear train; the time correction mechanism comprising a clutch plate that engages a shaft of one of the two gears which mesh with each other; the time correction mechanism comprising a winding stem that turns the clutch plate between a first angular position, in which one of the two gears meshes with the other, and a second angular position, in which meshing of the two gears is released; the clutch plate comprising an abutment; a turning restricting portion comprising an abutted portion that abuts against the abutment of the clutch plate in order to position the clutch plate in the first angular position, and to restrict further turning of the clutch plate; and and an abutment surface formed on at least one of the abutment of the clutch plate and the abutted portion of the turning restricting portion, and which bears on the other of the clutch plate and turning restricting portion, the abutment surface defining a surface substantially perpendicular to a straight line connecting between centers of rotation of the two gears.
