Abstract (en)
The wristwatch has a calendar mechanism (50) driven by a moon indicator and actuating Chinese calendar indicators. The mechanism has a month mobile (70) driven by a lever (60) so as to complete one revolution for every common year of twelve months and for every leap year of thirteen months. The moon indicator displays a lunar date on a scale and is driven by clock movement to complete one revolution over one or two synodic lunations.
