Abstract (en)
[origin: CN114675522A] The invention relates to a drag-type bounce timepiece display mechanism equipped with a display break lever, arranged to display, in succession in a bounce manner, at least one first indication and at least one last indication which are distinct, comprising:-a display wheel; a display pinion and a fixed display wheel; -a pivoting holding element; a drive wheel; a return element; -a display disconnection lever; -the holding element and the display breaking lever are arranged such that, when the bounce-back timepiece display mechanism moves from the display of the last indication to the display of the next first indication, the holding element pivots, the display breaking lever is locked, such that the elastic strip becomes strained and the holding element is forced to be released from the teeth of the fixed display wheel; the return element is arranged in the rebound timepiece display mechanism such that stresses caused by the return element in the rebound timepiece display mechanism can be released and such that the rebound timepiece display mechanism can be returned in a rebound direction into its initial position, in which the rebound timepiece display mechanism displays a first indication.
