A linkage mechanism (100) for a horological mechanism, for transmitting a movement between an actuator and a receiver, including a structure (10) relative to which a carrier (9), movable according to a single degree of freedom under the action of the actuator, is connected to the structure (10) by at least one flexible guide (50), each of the carrier (9) and the structure (10) being more rigid than each flexible guide (50), at least one flexible guide (50) is planar, and includes flexible necks (51), with a smaller section than the elements that are adjacent thereto, and/or flexible blades (5, 6, 52), with a smaller section than the elements that are adjacent thereto, and forming articulations. At least two arms are articulated to the structure (10) at two distinct points, and kinematically cooperate with each other, or with a tertiary bar or a tertiary structure.

Disclosed is a display mechanism for a timepiece, including a frame, an aperture which is fixed relative to the frame and a first and a second display disc each bearing indications, characterized in that it makes it possible to display the indications of the first and second discs alternately through the aperture. The invention also relates to a timepiece movement including such a mechanism, and to a timepiece such as a wrist watch, a pocket watch, a clock or a miniature clock including such a timepiece movement.

A dragging type retrograde horological display mechanism, arranged to successively display first and distinct indications in a retrograde manner, including a display wheel driven by a drive wheel; a pivoting holding element engaged in a toothing of a fixed display wheel; a return element that constrains a display pinion in rotation; a display disconnection lever including an elastic strip; when the retrograde horological display mechanism moves from the display of the last indication to the display of the next first indication, the holding element pivots, whereas the display disconnection lever is locked, such that the elastic strip becomes strained and the holding element is forced to be released from the toothing of the fixed display wheel, thus enabling the stress induced by the return element to relax and return the retrograde horological display mechanism in the retrograde direction in the initial position to display the first indication.

The invention relates to an indicator device (D) for watchmaking, in which a drive toothed wheel (3) rotates a driven programme wheel (2) which is configured substantially as a circular crown with an external toothing (20) and an internal toothing (21). The latter meshes with an eccentric internal toothed wheel (1), whose cycloidal rotary movement with a suitable transmission ratio, allows the information given on the programme wheel (2) to be indicated. The device is suitable for making perpetual calendars of the clocks.
