Abstract:
1. A timepiece display device including a rotating analogue indicator member, a first counter wheel set and a second counter wheel set, whose positions respectively represent a first magnitude and a second magnitude to be displayed by said indicator member, and a switch mechanism with manual control for selectively displaying the first or second magnitude via the indicator member, wherein the switch mechanism includes a rotating arbour kinematically connected to the indicator member and a sliding wheel set secured to the arbour in rotation and provided for sliding, via the action of the manual control device, so as to selectively occupy on the arbour a first axial position in which the sliding wheel set is coupled with the first counter wheel set, and a second axial position, in which the sliding wheel set is coupled with the second counter wheel set, and wherein the switch mechanism further includes first phase synchronisation means for adjusting the angular position of the rotating arbour to that of the first counter wheel set when the sliding wheel set occupies the first axial position, and second phase synchronisation means for adjusting the angular position of the rotating arbour to the position of the second counter wheel set when the sliding wheel set occupies the second axial position.
