发明名称 CALENDAR MECHANISM FOR DISPLAYING THE DATE AND THE DAY OF THE WEEK IN ONE TIMEPIECE
摘要 The invention is a timepiece calendar mechanism for displaying the date and the day of the week, including a date indicator in the form of an internally toothed crown. The date indicator is driven by a first drive wheel having an external toothing so as to be able to be driven about an axis of rotation by a wheel set secured to an hour wheel of the timepiece. The toothing includes a prominent tooth, longer than the others, which abuts against a tooth of the inner toothing of the date indicator to move it forward one day in a time interval located around a determined time of the day. The mechanism also includes a day of the week indicator that moves forward one day during the time interval.
