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 sympathetic timepiece assembly (1000), including a sympathetic watch (200), and a sympathetic clock (100) with a receptacle (150) for receiving the watch, for the power recharging and/or the display adjustment and/or the rate adjustment controlled by the clock (100) or by the watch, through a connection mechanism including at least two distinct transmission lines between the clock and the watch in the transfer position, the watch including a resonator (10), and a display gear train and a finishing gear train, and, or else a stop mechanism (20) arranged to stop the operation of said resonator, or else a coupling mechanism allowing to separate the display from the finishing gear train, or else both such a stop mechanism and such a coupling mechanism, and the watch including at least one hour display (4) and one minute display (5).

A biometric button assembly may be disposed in an opening of an enclosure of an electronic device. The biometric button assembly may include an input member that forms an exterior surface of the button housing and is configured to receive inputs, for example from a user of the electronic device. The biometric button assembly may further include a biometric sensor for detecting the received inputs and transmitting a signal to a processor of the electronic device. The signal may correspond to a biometric characteristic, such as a fingerprint. A flexible conduit may transmit the signal to the processor. A portion of the flexible conduit and a seal may be positioned between the button assembly and the enclosure that prevents contaminants from entering the button housing and the enclosure.

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.

A switch device including a base member provided with a stem insertion hole, an operation member which has an engaging groove provided in an outer circumferential surface thereof, and is slidably and rotatably inserted into the stem insertion hole of the base member, a stopper member having an engaging portion which is arranged in the engaging groove of the operation member and moved along with sliding of the operation member, and a release member which releases the engaging portion from the engaging groove, in which the release member includes a pressing portion which is operated from one surface side of the base member so as to release the engaging portion from the engaging groove.

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.

A push button capable of improving shock resistance and a timepiece equipped therewith are provided. This push button includes an operation member having a shaft section inserted into a through hole of a case and a head section provided on the outer end of the shaft section, and an elastic member which presses the head section toward the outside of the case or is elastically deformed, and this elastic member includes a buffer section that buffers a pressure externally applied to the head section which is greater than a predetermined pressure. Accordingly, when a pressure greater than the predetermined pressure is applied to the head section, the head section comes in contact with the buffer section while elastically deforming the elastic member so as to buffer the pressure. By this structure, shock resistance is improved.
