Abstract
A timepiece having a mode displaying function includes an external operating member that is rotatable by a user. A sliding pinion rotatable by the external operating member rotates a transmitting gear. A correction transmitting wheel is rotatable by the transmitting gear. A motion control gear is fixed to the correction transmitting wheel. A motion control spring member having a motion control part contacts with a respective motion control face of the teeth of the motion control gear to regulate the rotation of the correction transmitting wheel during the rotation of the motion control gear. A mode displaying plate is rotatable by the correction transmitting wheel and displays the modes of the timepiece. The mode displaying plate is fixed to a display gear which has a plurality of teeth. A spring member has an urging surface for contacting with a respective motion control face of the teeth of the display gear. Thus, during rotation of the display gear, the urging surface of the spring member regulates the rotation of the mode displaying plate so that the modes printed on the display plate are consistently viewable at the center of a display window on the dial of the inventive timepiece.
