Abstract
A timepiece including a timepiece mechanism (200) and a display device (100) for displaying a magnitude relating to the timepiece mechanism (200), in combination on wheels (1 2) driven by rotational movements in the same direction of rotation by at least one output (3; 4) of the timepiece mechanism (200), at least one wheel (1; 2) being integral in rotation with an indicator (60) to display a representation of this magnitude by the angular difference between the wheels (1; 2) or between a wheel (1; 2) and a fixed scale, the timepiece mechanism (200) driving, at a given time, a single wheel (1; 2) by a single output (3; 4), the display device (100) driving one of the wheels (1; 2) by another, and the display device and/or the timepiece mechanism can disengage in at least one end-of-travel position of a wheel (1; 2).
