Abstract (en)
The timepiece date mechanism includes a finger (9b) kinematically connected with an instantaneous-jump cam (7) in order to drive a calendar mobile. The driving finger is borne by a release member (9) that is pivotally mounted about two axes(3a,7a), one (3a) of which that of the driving mobile (3). The release member has an opening (9a) configured to allow an angular displacement about the second of the two axes (7a), so that the driving finger can be released from the toothing (1a) of the calendar ring while the calendar is corrected. A return spring (8) tends to rotate the driving finger about the second pivot axes in order to bring it to butt against an edge of the opening, a position in which the driving finger is engaged with the toothing of the calendar ring.
