A watch includes a timepiece movement including a mechanism for displaying a time period or season which includes a first wheel which is provided in order to turn once in thirty-one days for displaying a day of the month, and a second wheel for displaying another time period or season. The second wheel turns more quickly than the first wheel for displaying this time period or season, and the second wheel is provided in order to be displaced from the first wheel, at the rate of one turn in a period of time between 340 days and 380 days.

A timepiece mechanism including a deformable rhombus including four coplanar segments pivotally connected in pairs by their vertices, including an input segment adjacent to an output segment, both pivoted about a pivot axis perpendicular to the plane of the rhombus and passing through a first vertex common to the input and output segments and locked in translation in the plane of the rhombus, a lever mounted to pivot about the pivot axis, the lever being kinematically connected in rotation, about the pivot axis, to a second vertex of the rhombus, opposite to the first vertex, a first locking member movable between a first locking position, in which the lever is locked in rotation, and a first unlocking position in which the first locking member does not hinder rotation of the lever, a second locking member movable between a second locking position, in which the second vertex is locked in translation in a radial direction, and a second unlocking position in which the second locking member does not hinder radial movement of the second vertex.

A variable timepiece display mechanism includes a resilient hand with a drive pipe integral with a single-piece flexible strip including flexible segments joined at tips, a first segment thereof extends between the first pipe and a first tip. The mechanism also includes a driver for driving the pivoting of the pipe, and a stressor for stressing the first flexible segment in order to vary the position of the first tip relative to the output axis, as a function of the forces applied to the flexible strip. The drier and/or the stressor includes a first shaped gear train and/or a second shaped gear train in order to accelerate, stabilize the speed of, or slow at least the pipe over a part of the angular travel thereof.

The invention relates to a mechanism for displaying an information for a timepiece, comprising a mobile (10) intended to be driven in rotation by the movement of the timepiece about a display axis (17), a satellite (20) pivoted on the mobile (10) about a satellite axis (27) parallel to the display axis (17) and remote from a non-zero distance d1 thereof, a display area (80), an indicator (50) secured to the satellite (20) and the position of which relative to the display area (80) provides the information, and a crown (30) centered on the display axis (17) and kinematically connected to the satellite (20). The mechanism is particular in that the indicator (50) is located at a distance d2 from the satellite axis (27), which is greater than or equal to the distance d1.

A dial for a timepiece, preferably a watch, the dial being provided with a relief portion which is made as an assembly of pieces on different levels, juxtaposed on a base, such that the relief portion is formed by the upper surfaces of the pieces. A method for manufacturing the dial with several separate pieces, the upper surfaces of the pieces being subjected to a polishing step and/or possibly an enamelling step. The pieces are then cut along a defined contour and then assembled edge-to-edge on a base, so as to create the relief portion.

A trigonometric function display clock includes a clock face that has a center aligned with a central axis, axial markings aligned with an x-axis and a y-axis, and a secondary circle having a diameter equal to a radius of the axial markings. A first point on the secondary circle is aligned at the center of the central axis, and the secondary circle is configured to be rotatable about the first point. The secondary circle is configured to overlap and align with at least a portion of the axial markings as the secondary circle rotates about the first point.

Mechanism for a watch movement (1) comprising a cam (5), a rack (3) driven by the cam (5), a retrograde mobile (20) driven by said rack (3) and bearing a retrograde indicator (2) for displaying a first item of time information, the rack (3) and the retrograde mobile (20) being arranged in such a way as to rotate in the same direction. A jumping hour display ring is synchronized with the returns of the retrograde display.

A timepiece display mechanism including at least a first retrograde drive device for a first display member displaying a first magnitude, and a second retrograde drive device for a second display member displaying a second magnitude, the first retrograde drive device including a first drive rack to exert on a first wheel set driving the first display member, an opposite force to a resistance force exerted by a first return rack, the second retrograde drive device including a second drive rack to exert on a second wheel set driving the second display member, an opposite force to a resistance force exerted by a second return rack, wherein the pivot axes of the first drive rack and of the first return rack are remote, and/or the pivot axes of the second drive rack and of the second return rack are remote.
