A system for adjusting the angular position of a first toothed wheel set relative to a support on which the first toothed wheel set is mounted such that it can pivot. The adjusting system includes an adjusting member allowing an action to be applied to an angular position of the first toothed wheel set so as to adjust the angular position of the first toothed wheel set relative to the support. A timepiece can include such an adjusting system.

A date calendar display mechanism driven via a kinematic chain by a horological movement of a timepiece. A first and second date indicators, the first date indicator remaining still during a 24-hour period separating the passage from the last day of a month having 31 days to the end of the first day of the following month, the kinematic chain including a wheel continuously engaged with the horological movement and having a toothing via which the wheel meshes with a pinion which contributes to driving the first indicator, the wheel being, at one point, devoid of teeth such that, during the above 24-hour period, the wheel does not mesh with the pinion and remains still. A dual jumper pivots about an axis with a first beak via which it is engaged with a toothing of the first date indicator and, at a second beak via which it is engaged with a toothing of the pinion, the dual jumper being elastically held engaged with the first date indicator and with the pinion.

A moon phase display includes a frame and a plurality of display elements supported by the frame and rotatable relative to the frame. The plurality of display elements further includes a first side face on which an illuminated moon portion is depicted and a second side face. A first rotational position in which the first side face is arranged along a display plane wherein the first side faces together arranged on along the display plane represent a full moon. A second rotational position in which the second side face is arranged along the display plane. A drive rotates each of the plurality of display elements independently. A controller actuates the drive so that each one of the plurality of display elements is rotated into the second rotational position until all of the plurality of display elements are located in the second rotational position.

A system adjusts the angular position of a first toothed wheel set relative to a support on which the first toothed wheel set is mounted such that it can pivot. The adjusting system includes an adjusting member allowing an action to be applied to an angular position of the first toothed wheel set to adjust the angular position of the first toothed wheel set relative to the support. The invention adjusting system can be incorporated into a timepiece.

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.
