Abstract

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.

Dependent claims

A watch mechanism comprising an element for display of time, a first element for display of a first piece of watch information derived from time and a second element for display of a second piece of watch information derived from time, the mechanism comprising:

a first kinematic chain for simultaneous correction of the display of time, the display of the first piece of watch information and the display of the second piece of watch information,
a second kinematic chain for correction of the display of time independently of the display of the second piece of watch information, and
a third kinematic chain for correction of the display of the second piece of watch information independently of the display of time and the display of the first piece of watch information, the third kinematic correction chain comprising an epicyclic gear train,
the epicyclic gear train being connected kinematically to the element for the display of time by a notched wheel, and the first and second kinematic chains comprising the notched wheel.
