Abstract (en)
[origin: US2021364989A1] A retrograde timepiece display mechanism for a watch including a wheel for displaying information, this display wheel being driven by a drive finger carried by a wheel driven by a horological movement, in order to change the information displayed by the retrograde timepiece display mechanism from one value to the immediately following value, this retrograde timepiece display mechanism including also an intermediate correction device to manually correct the information provided by the retrograde timepiece display mechanism by acting on a correction finger which drives the display wheel, the retrograde timepiece display mechanism also including a safety device arranged to allow blocking the intermediate correction device by preventing the correction finger from driving the display wheel during a period of time when the change in the information displayed by the retrograde timepiece display mechanism occurs and when the drive finger is engaged with the display wheel.
