Abstract:
1. A watch comprising a mechanism for driving a device that displays a time-dependent value, this drive mechanism itself being driven by a movement of the watch, this driving mechanism having a finger by which it is capable of driving the display device forwards and backwards when it is itself driven by a first correction element acting on said display device via a clockwork gear train and said drive mechanism, the finger being capable of being moved aside when the display device is acted on directly via a second correction element, wherein the drive mechanism has a drive wheel carrying the finger, this finger being fixed to a spring by means of a first pin about which it can pivot, the pivot angle of said finger being limited by a second pin to which it is fixed and which is engaged in a hole made in the drive wheel, the spring holding the finger in a position in which it is engaged in a toothing of a driven wheel of the display device in order to drive this wheel in a clockwise or anti-clockwise direction, this spring allowing said finger to free itself from the toothing of the driven wheel when the display device is being corrected by the second correction element.
