A winding device on a structure of a movement or watch case, including a telescopic push-piece, independent of the control stem, driving a rack for winding a barrel, and including, between a pipe fixed to the case and an operating head, first elastic return device tending to move the head away from the pipe, this head being capable of occupying an angular, longitudinal locking position corresponding to a rest position, or an angular position of freedom allowing axial mobility, or a stop position wherein it has one degree of freedom, this rack, which is movable against second elastic return device, cooperates with a winding wheel set meshing with an intermediate rack actuated by a return spring of the second elastic return device.

A horological movement including a tourbillon or karussel frame carried by an arm subjected to the torque of a first energy source, and a second energy source driving a frame pitch mobile driving the frame, and, for periodically controlling a retrograde movement of the arm, a release mobile connected to the second energy source and cooperating at a pallet-stone with an interrupted cam that a cam mobile kinematically connected to this arm includes, to allow advancing the arm in a direct direction as long as the pallet-stone is resting on the cam, and to control a rapid retrograde return of this arm during a drop of the pallet-stone between two of its successive support surfaces on the cam.
