Abstract:
Timepiece with a mechanism for winding and for correcting at least two indicator members, comprising a winding stem, a pull-out piece engaged, on the one hand, with this stem and, on the other hand, with a jumper spring defining three axial positions of the said winding stem, corresponding to those for winding, for correcting at least one indicator member indicating a function derived from time, and for setting the correct time, the said winding stem carrying a winding pinion and a castle wheel engaged with a bar acted upon by a spring and connected to the said pull-out piece to selectively place the said castle wheel in engagement with the said winding pinion and with a minute-wheel geartrain when the said winding stem is in the extreme positions, characterized in that the said mechanism comprises two first connecting wheels which are superposed and arranged one on each side of the said winding stem, pivoted about two respective stationary axes and meshing with the said winding pinion, two second connecting wheels pivoted about two respective stationary axes, meshing respectively with the said first connecting wheels, two bars, namely a winding bar and a correcting bar, which are pivoted coaxially to the respective axes of pivoting of the said second connecting wheels, one carrying a winding reverser pinion and the other a correcting pinion meshing with the said respective second connecting wheels, means of connection between each of the two bars and the said pull-out piece to act on the said bars according to the axial position of the said winding stem so as selectively to place the said winding reverser pinion in engagement with a winding ratchet wheel, in the said winding position, and the said correcting pinion in engagement with the said member for indicating a function derived from time, in the said correcting position.
