Abstract (en)
[origin: WO2017158527A1] The invention relates to a watch movement comprising a retrograde moving part, an hour ring having an internal asymmetric toothing and driven by the retrograde moving part so as to display the current time in a jumping manner, a correction mechanism allowing the retrograde moving part to be corrected in a two-directional manner, and a driving body which is actuated by said correction mechanism and engaged with said internal asymmetric toothing such that the corrections of the retrograde moving part in the clockwise direction are transmitted to the hour ring, while the corrections in the anti-clockwise direction are not transmitted to the hour ring.
