摘要： A leap-year display mechanism for a horological movement with a perpetual calendar display including a drive element connected to a month wheel set rotated by one step per month, a transmission star intended to be attached to a structure of the horological movement, arranged along the stroke of the drive element so as to be rotated thereby when the month wheel set completes one full revolution, a leap-year display connected to the transmission star via a reduction gear train so that with each revolution of the month wheel set, the leap-year display is rotated by one step.

摘要： A method for frequency tuning a set of plates of a watch. The plates are disposed one above the other forming a watch dial with a space defined between the plates. A mechanical shock to the set of plates is generated, and the vibration frequency of each plate is checked. The vibration frequency of at least one of the plates is matched if different from the other plate so as to obtain an identical vibration frequency for each plate in order to tune the plates at least according to the first vibration eigenmode so as to avoid any contact between the plates as a result of any mechanical shock.

摘要： 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.

摘要： An actuation mechanism (60) of a flexible hand (44) to which a clockwork movement applies a first angular rotation (θ1), the flexible hand (44) including a first drive barrel (46) and a second drive barrel (50) connected to a tip (54) of the flexible hand (44) by a first and a second flexible arm (48), the first drive barrel (46) being provided with a first toothing (56) and the second drive barrel (50) being provided with a second toothing (58), the first and second drive barrels (46, 50) being mounted so the first toothing (56) of the first drive barrel (46) engages with the second toothing (58) of the second drive barrel (50) in the stressed position of the flexible hand (44), the angular rotation (θ1) applied by the clockwork movement to the actuation mechanism (60) being modulated by an angle of rotation (φ) by the actuation mechanism (60).

摘要： A device for selecting and controlling functions of a horological movement, including a selector member arranged such that, when it is acted on, it causes a column wheel including a plurality of coaxial cams which are integral with one another for rotation as one, to rotate in a single direction of rotation, the device including a plurality of transmission yokes, each of which is arranged such that it bears against a cam specific thereto so as to be able to successively occupy, depending on the angular position of the cam, a rest position and an active position, each transmission yoke being configured such that when it occupies the active position, it is disposed in the path of a control member which is intended, when it is acted on from a rest position, to drive the transmission yoke located in an active position, towards a position for controlling a function specific thereto.

摘要： The invention relates to a method for step-by-step time setting of a sympathetic watch (200) by a sympathetic clock (100), forming together a sympathetic assembly, where a predetermined time-setting step and a reference position of the displays (3; 4; 5) of the watch (200) are determined, and where the clock (100) performs the time setting of the watch (200) by positioning a transmission line in a position corresponding to the time setting, and by actuating, in successive steps, each of the value of the predetermined step, a transmission line capable of imparting to a time-setting mechanism internal to the watch (200) any movement necessary to precisely achieve the display of the current time.

摘要： A method for acquiring data on a sympathetic clock (100) for setting the time of a sympathetic watch (200) at request. The sympathetic watch forms with the clock (100) a sympathetic assembly (1000). The watch includes an hour display (4) and a minute display (5), a reference position of which will be defined at a reference time, and the clock (100) performs the time setting of the watch (200), either when the watch (200) is placed on the clock (100), or alternatively at a predetermined time on the clock (100), or at request by action of a user on a control means (300) included in the clock (100) or the watch (200), or upon control of a horological movement (900) included in the clock (100).

摘要： A method for reference time setting of the displays of a sympathetic watch by a sympathetic clock forming a sympathetic assembly with the watch. At any time, the reference time setting of the watch is performed by a first phase during which the placement in the reference position is triggered, by a first displacement of an interface between the clock and the watch, the reference time setting of the displays, and the coupling mechanism is uncoupled to allow the rack to drive the display gear train of the watch in the counter-clockwise direction, over as many revolutions as necessary, until the pawl meets the ratchet tooth opening of the hour cam, then the time-setting mechanism controlled by the clock sets the time of the displays of the watch in the clockwise direction to the exact time by recoiling the rack, then the coupling mechanism is recoupled.
