Abstract
A mechanism for displaying and correcting a state of two different time measurable quantities for a timepiece includes a movement driving a first display mechanism to display a first measurable time quantity and a second display mechanism to display a second measurable time quantity, and including an adjusting member. The first and second display mechanisms respectively include first and second drive mechanisms sharing a common drive mechanism driven by the movement, and controlling a driving of one of the display mechanisms by instantaneous jumps and of the other by dragging. The display mechanisms respectively include a first and a second correction mechanism, sharing a common correction mechanism driven by the adjusting member independent of the common drive mechanism, including a friction safety device.
