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 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.

A component of a winding device, in particular an automatic winding device, of a timepiece movement, wherein it is made of austenitic stainless steel and wherein it comprises at least one friction surface hardened by carbon or nitrogen type atoms introduced into the austenitic stainless steel over a predetermined depth.

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 watch self-winding device with rotary motion, including a base carrying a motor driving in rotation a support carrying a watch and includes an upper watch holder with a surface in direct contact with a watch, this support includes a microphone for listening to a watch and an embedded electronic circuit processing the signal from the microphone, the device includes, in order to supply power to the embedded electronic circuit, a first coil fixed to the base and powered by a power source carried or relayed by the base, and a second coil embedded in the support, coaxial to the first coil and arranged to transmit power to the embedded electronic circuit, which is arranged to exchange information with a static electronic circuit in the base.

A marine chronometer includes a clock mounted on a support, for example mounted so that it can be inclined with respect to the support using a gimbal mounting, the clock including, inside a case, a mechanical clock movement driven by a barrel, and the clock also including a rewinding control member engaged with a rewinding geartrain for rewinding the barrel. The rewinding control member includes a rewinding control geartrain positioned on the outside of the clock, secured to a spindle passing through a wall of the case via a bearing, the through-spindle being engaged with the rewinding geartrain.

A watch interaction simulation apparatus for carrying out interaction with a watch interaction member for a watch includes a sensor device adapted to be coupled with the watch interaction member. The sensor device is operable to sense an interaction with the watch interaction member. The apparatus includes an actuator device being coupled to the watch interaction member, an actuator control device for controlling the actuator device, and a sensor information computing device being operatively coupled to the sensor device.

Disclosed is watch interaction simulation system, a watch interaction simulation apparatus, watch interaction simulation methods and a computer software product including executable software code for carrying our watch interaction simulation methods.

A universal device is for preparation of a watch with a gain/loss correction crown and an oscillating resonator. The device includes winding and a gain/loss corrector with a robotic manipulator for manoeuvring the crown. It also includes an adjustment device with a gain/loss correction device including a gain/loss-corrector oscillator generating an oscillation to subject the watch to an oscillation at a correction frequency NC and/or to a modulated movement. The gain/loss correction device includes a gain/loss controller that controls the oscillation of the gain/loss-corrector oscillator, interfaced with a device to measure the gain/loss of the watch. The gain/loss correction device also includes an automatic winder with a watch-holder stand subjected to the oscillations or movements generated by the gain/loss-corrector oscillator.
