Abstract: Autonomous control mechanism (100) for a movement, comprising a control stem (10) moveable relative to a bar (80) between stable stem positions, for controlling the pivoting, in each of said positions, of a single control train of the control trains of said mechanism (100). It includes, on a first side (81) of said bar (80), a first control train (810), and on a second side (82) opposite said bar (80), a second control train (820). Every stable position of the control stem (10) drives a stable position of a pull-out piece (20) fitted to one of said sides and moveable relative to a boss (210) of said bar (80). In said stable pull-out piece position, any movement applied to the control stem (10) causes the pivoting movement, of either a single first control train (810), or a single second control train (820).

Abstract: An electronic timepiece movement including a timepiece motor formed by an assembly comprising a frame made of non-magnetic material and a rotor housed in said frame; and method of manufacturing a motor of this type wherein the frame is first made with a lateral aperture, said frame including a first part and a second part each carrying a bearing, the first part or the first and second parts of the frame being elastically deformable. Next, the rotor is mounted in the frame through the lateral aperture therein by increasing the distance between the two bearings of the frame via the elastic deformation of the first part or of the first and second parts of said frame, said elastic deformation being provided in particular for the insertion of the two rotor pivots into the two respective bearings of the pre-formed frame.

Abstract: The invention is a timepiece calendar mechanism for displaying the date and the day of the week, including a date indicator in the form of an internally toothed crown. The date indicator is driven by a first drive wheel having an external toothing so as to be able to be driven about an axis of rotation by a wheel set secured to an hour wheel of the timepiece. The toothing includes a prominent tooth, longer than the others, which abuts against a tooth of the inner toothing of the date indicator to move it forward one day in a time interval located around a determined time of the day. The mechanism also includes a day of the week indicator that moves forward one day during the time interval.
