A display mechanism for n moonphases for a timepiece, where n≥3, includes a first wheel and pinion having a night-time background and a portion of lunar background and a second wheel and pinion superposed on the first, the second having a night-time background and moonphase profiles, with the first and second pivoting about one axis. The first wheel and pinion is driven at a constant velocity, and that the second can be driven in rotation at the same velocity and direction as the first during a moonphase display period during which a portion of lunar background of the first and a moonphase profile of the second corresponding to the moonphase to be displayed are superposed, revealing the moonphase. The second wheel and pinion is offset from the first by a repositioning angle during a transitional period between the current and following display periods, revealing the following moonphase.

Moonphase display mechanism

The invention relates to a mechanism for displaying an information for a timepiece, comprising a mobile () intended to be driven in rotation by the movement of the timepiece about a display axis (), a satellite () pivoted on the mobile () about a satellite axis () parallel to the display axis () and remote from a non-zero distance dthereof, a display area (), an indicator () secured to the satellite () and the position of which relative to the display area () provides the information, and a crown () centered on the display axis () and kinematically connected to the satellite (). The mechanism is particular in that the indicator () is located at a distance dfrom the satellite axis (), which is greater than or equal to the distance d

Trochoidal display mechanism

An instantaneous date control device for a timepiece, in particular for a mechanical wristwatch, including: a date disc, a gear train forming a kinematic linkage between the control device and a horological movement of said timepiece, a first mobile including a first toothed wheel driven at a speed of one turn per day and a cam mounted freely rotatably, over a limited angular range and/or in a single direction of rotation, as well as temporarily coupled in rotation to said first toothed wheel, a second mobile including a second toothed wheel driven at a speed of one turn per day, an unlocking and driving yoke carrying a feeler bearing on said cam and a driving finger which can mesh with teeth located on the date disc, an unlocking and driving spring, and a retaining means allowing to secure the angular position of the date disc between two instantaneous jumps.
