Abstract (en)
[origin: EP0549941A1] The invention relates to a timepiece including display means with automatic retrograde displacement. <??>This invention includes: - a clockwork movement, - a connecting wheel (22) entrained by the movement and including driving meshing teeth (26a-26y), - a system (16) for displaying information such as the date, - at least one oscillating element (30) tied to the display system (16) and including driven meshing teeth (32) engaging with the driving meshing teeth (26a-26y) of the connecting wheel (22), - means (34) of restoring the oscillating element (30), - disengaging means (40, 40a) for enabling the oscillating element (30) to make a free so-called retrograde displacement, and - a stop (B) associated with a counter-stop (CB) for limiting the retrograde displacement of the oscillating element (30), this invention being characterized in that the counter-stop (CB) consists of one (26a) of the driving meshing teeth (26a-26y) of the connecting wheel (22) which normally meshes, during entrainment, with the driven teeth (32) of the oscillating element (30). <IMAGE>
