Abstract
PURPOSE: To reduce the driving load of a calendar display member of a watch with calendar by controlling a calendar display member positioning mameber in synchronism with the drive of the member by a cam driven via gear train of the watch to thereby omit a spring member.
CONSTITUTION: A date plate 1 for displaying calendar is pushed at its teeth 1a by the end of a driving pawl 7 on a calendar feed wheel 6 rotating counterclockwise, and thus rotated. When the plate 1 is driven, the calendar feed wheel 6 introduces the tail 8a to be controlled of the positioning member 8 into narrow passage between first cam 10 and second cam 11 provided at the wheel 6 to thereby separate a stop surface 8b from the teeth 1a of the plate 1.
