A system for retaining a wrist watch in a watch winder having a hollow cylindrical turntable, includes a watch winder cuff defining a first circumferential profile, with two push tabs mounted on the cuff for inserting the cuff into the turntable and removing the cuff from the turntable, and one or more extension cuffs of differing length defining a second circumferential profile shaped to match the first circumferential profile, with a connector disposed thereon for engaging and joining the watch winder cuff and a selected extension cuff together. The connector may include a stub disposed on the extension cuff configured to fit snugly inside a depression on the watch winder cuff, or a hollow sleeve extending forwardly from the extension cuff and being configured to fit snugly over the watch winder cuff body to join the watch winder cuff and extension cuff together. The watch winder cuff preferably has an axial length of about one inch and the extension cuff, when joined to the watch winder cuff, preferably increases the axial length to about 2.25 inches to about 2.75 inches, depending on the size of the extension cuff. Both the watch winder cuff and the extension cuffs are made of compressible foam material such that the watch winder cuff and the extension cuffs are axially compressible under hand force.

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.

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).

A method for permanent time setting of a sympathetic watch (200) by a sympathetic clock (100) forming a sympathetic assembly (1000) with the watch (200) which includes an hour display (4) and a minute display (5), a reference position of which will be defined, and the time-setting is executed only at request by action of a user on a control means (300) included in the clock (100) or the watch (200), or automatically periodically controlled by the clock (100), and, to perform the time setting, the clock (100) drives the displays (4; 5) of the watch backwards, in the counter-clockwise direction, with a sufficiently long stroke to ensure that the displays (4; 5) pass through the reference position; or the clock controls means of the watch (200) which are disposed so as to ensure the displacement of the displays to the reference position by means of heart-pieces.

A coiling limitation device for a timepiece barrel includes at least one non-return notch arranged to cooperate with a sliding flange of the spring of the barrel, which is integrated in a watch including a resonator cooperating with an escapement mechanism. This device includes an acoustic device for the acoustic monitoring of the coiling of the barrel of a watch positioned on a receptacle included by the device, which acoustic devices are arranged to identify a click noise during each start of cooperation between the sliding flange and a notch. The device includes piloting devices arranged to stop the coiling of the barrel at the instant of the perception of the click noise or the repetition of the click noise.

The winding device includes a motorization device for driving a watch holder carrying at least one automatic watch with a mobile oscillating mass, and a measuring device for measuring the variation in the resistive torque opposed to the motorization device by the watch holder equipped with watches, depending on the degree of winding of the watches. The measuring device includes a speed measuring device to determine the speed and/or the variation in the speed of the motorization device, and/or include a torque measuring device to determine the value of the torque and/or the variation in the torque at the watch holder, and/or include a current measuring device to determine the value of the current and/or the variation in the current of an electric motor of the motorization device.

A presentation case is arranged for receiving an electromechanical watch provided with a stepping motor for driving the watch hands. The presentation case includes a box with a support for receiving the watch, a system for detecting the position of the hands, and a device for resetting the watch connected to the hand position detection system. The resetting device resets the watch based on information received from the hand position detection system and a time reference when the watch is placed on the receiving support. The resetting device includes a driver for the stepping motor of the electromechanical watch, which is arranged inside the presentation case facing the stepping motor, when the watch is placed on the receiving support, and causes a rotation of the stepping motor by inductive coupling.

An accessory (100) for an automatic watch (200) is provided. The accessory comprises a watch holder (120) carried by a first gimbal (130) in a manner to be rotatable about a first rotational axis A-A. The watch holder (120) is further rotatable about a second rotational axis B-B and rotation about the first rotational axis A-A and the second rotational axis B-B is caused by a first actuator (132) and a second actuator (122), respectively.

A winding machine includes motorization means arranged to move a support, carrying at least one watch or one horological movement, along a path in a plane. The motorization means are arranged to move each support parallel to a starting position corresponding to the loading or unloading of a watch or of a movement on the support, the axes of a three-dimensional frame of reference specific to the support always remaining parallel to the oriented directions that the axes occupy in the starting position.
