TIMEPIECE INCLUDING MONTH DISPLAY

PROBLEM TO BE SOLVED: To solve the problem wherein a date indicator itself, and hence a timepiece itself becomes thick because of projections and pins for month drive in a prior art when using the date indicator and a month feed pinion in combination, and costs increase since the date indicator is special. SOLUTION: In a timepiece including month display, a tooth for month drive is installed at an outer periphery of the date indicator. Thus, the date indicator can be created to be as thick as before, and a thickness and costs can be made identical to those of a conventional timepiece for only date display. Also, by disposing a first intermediate wheel meshed with an external tooth at an outer periphery of the date indicator, and disposing a second intermediate wheel so as to overlap with the date indicator in a plan view, month display can be performed at an inner periphery of the date indicator.
