Watch mechanism (100) including an element for the display of time, first and second elements (Q, PDL) for the display of first and second pieces of watch information derived from time, the mechanism including: —a first kinematic chain (CC1) for the simultaneous correction of time display, and the display of the first and second pieces of watch information; —a second kinematic chain (CC2) for the correction of the time display independently of the display of the second piece of watch information, and —a third kinematic chain (CC3) for the correction of the display of the second piece of watch information independently of the time display and the display of the first piece of watch information. The third chain includes an epicyclic gear train (TE) connected kinematically to the element (H) for the time display by a notched wheel (MC) included in the first and second kinematic chains.
