ABSTRACT:
A calendar mechanism-equipped timepiece having a compactly constructed drive mechanism for driving first and second date indicators is offered. A timepiece equipped with a calendar mechanism has a drive mechanism, time display wheels, a first date indicator for displaying the ones digit of the date, a second date indicator for displaying the tens digit of the date, and a program wheel capable of intermittently rotating the first date indicator and the second date indicator based on the operation of the drive mechanism. The center axis of rotation of the time display wheels is located within the center hole of the program wheel under the condition where the time display wheels are rotatable. The first and second date indicators are placed in position adjacently to each other. Information about the date can be displayed from a window in the dial by one of the first date characters on the first date indicator and one of the second date characters on the second date indicator.
