发明名称 Watch with calendar mechanism equipped with month indicator and date indicator
摘要 The present invention aims to provide a watch with a calendar mechanism which allows a reduction in the thickness of a date feeding mechanism and a month feeding mechanism. In a watch with a calendar mechanism according to the present invention, a date indicator includes a month end tooth for driving a month feeding lever at the end of a month and feeding the date indicator at the end of a shorter month. A month indicator includes a month cam for operating a shorter month end feeding lever at the end of a shorter month. The shorter month end feeding lever can feed the date indicator by one day based on the rotation of a date indicator driving wheel and the rotation of the month cam. The month feeding lever moves toward the month indicator at the end of a month based on the rotation of the date indicator, and can feed the month indicator by one month.
