Abstract:
1. A calendar mechanism for a timepiece, comprising: a date wheel set to control a date indicator, the date wheel set including first teeth and being configured to be driven step-by-step by a timepiece-movement contained in the timepiece, a month wheel set including second teeth and being configured to control a month indicator, a monthly drive part to increment the month wheel set at an end of each month, the date wheel set being arranged to actuate the monthly drive part during a change from an end of one month to a first day of a next month, and a push-button and a quick corrector device arranged to be manually actuated by the push-button, the quick corrector device being configured to advance the date wheel set, independently of any particular initial angular position of the date wheel set, in one stroke of the push-button until the date indicator changes to a following month while actuating in passing the monthly drive part, wherein the quick corrector device includes a rotating stop member kinematically connected to the date wheel set, and a stop mechanism moveable between an active position in which the stop mechanism intercepts a trajectory of the rotating stop member and an inactive position, and wherein the quick corrector device is arranged to bring the stop mechanism into the active position and to advance the date wheel set in one stroke of the push-button until the stop mechanism stops the rotating stop member and immobilizes the date wheel set in an angular stop position corresponding to an indication of a first day of a month.
