A timepiece incudes a crown (4) housed in a cavity (10) provided in the case and open towards the outside, such as a cavity (10) in the side wall of the case (1) of a wristwatch, in the rest position of the crown (4). To bring the crown out of its rest position, the user rotates a rotary knurling-roller (5). The knurling-roller (5) is coupled to a tube (15) wherein is inserted a crown body (18) integral with the crown. The rotation of the knurling-roller actuates rotation as well as translation of the tube, which is linked only in translation to said cylinder (18). The tube displaces the crown in an axial direction without rotating the crown around its central axis (6). At least one control position of the crown and the rod can be reached, by rotating the knurling-roller (5) without having to manually pull the crown outwards.

The present invention relates to a watch protective case with a knob, including a soli rubber case body covering the outside of a watch in a cooperative manner and a hard rubber cover connected to the soft rubber case body in a cooperative manner on an upper end of the watch. A first soft rubber watchband and a second soft rubber watchband are respectively provided at two ends of the soft rubber case body, an adjustment hole is opened in a position on the soft rubber case body that corresponds to a watch button, and a knob adjustment component connected to the watch button in a cooperative and adhesive manner is provided within the adjustment hole. In addition, the adjustment hole is blocked by the knob adjustment component, which can effectively provide dust-proof and aesthetic effects.

A watch includes a control member, for example a crown or a head of a push-piece, which is mounted in a resilient manner on the outer end of an elongated element projecting outside the middle, such that a user can tilt in a self-reverting manner the control member in two dimensions orthogonal and perpendicular to the central axis of the elongated element. At least one proximity sensor is incorporated into the middle of the watch, in a location allowing this proximity sensor to produce an electric signal that represents the tilting of the control member about an axis that is perpendicular to the central axis. A processor generates at least one instruction on the basis of the electric signal provided by at least one proximity sensor, for example to allow the user to browse a menu or a calendar displayed on a digital screen.

The present invention relates to a control device (10) for a horological movement including, on the one hand, a first part (100) comprising a sliding guide tube (101) intended to be fixed relative to said horological movement and an activation module (120), and on the other hand, a second movable part (200) slidably guided by the guide tube (101) in a direction called “axial direction”, relative to said first part (100), between an active position wherein it is able to be integral, by means of an adjustment rod (201), with a component of the horological movement, and an inactive position wherein said adjustment rod (201) is intended to release the component of the horological movement, said second part (200) comprising a slider (202) fixed to the adjustment rod (201) and cooperating with the activation module (120) so that they exert mechanical stresses on each other when the second part (200) moves between the active and inactive positions, and so that these mechanical stresses are released when the second part (200) reaches one of the active or inactive positions.

A watch including a control member that is able to manage at least one first function of the watch and at the same time to control one or more additional electronic functions. The control member, for example a crown or a push-piece head, is mounted on the elongate element defining a central axis and passing through a wall of the watch middle. At least one strain gauge is mounted around the elongate element and arranged so as to produce an electrical signal representing a radial force exerted by the elongate element on the strain gauge when a user laterally exerts a force on the control member. A processor generates at least one command on the basis of the electrical signal, for example to enable the user to navigate in a menu or a calendar displayed on a digital screen.

An external watch control device (100) including a crown (1) carrying a first barrel (2) screwed onto a tube (4), coaxially guiding a second barrel (3) includes a driver (7), the first barrel (2) and the second barrel (3) including opposing unidirectional toothing (8; 9), the tube (4) containing a spring (11) tending to move the first barrel (2) away from the driver (7), the unidirectional toothing (8; 9) are at maximum distance when the crown (1) is completely screwed onto the tube (4), and in meshing position when the crown (1) is completely unscrewed, the cooperation between the unidirectional toothing (8; 9) allowing the rotation of the first barrel (3) in a first single direction of rotation of the crown (1), and preventing it in the opposite direction against the spring (11) in the manner of a pawl.

A multifunction correction device (100) for a case (2) of a timepiece including a horological movement (1). The correction device includes: a cylindrical body (110) integral with the timepiece case (2); a primary correction module (120) moving in translation in a first direction, having a primary control member (121) integral with a primary control stem (123), which operates a first function corrector (10) of the horological movement (1); and a secondary correction module (130) moving in translation in a second direction parallel to the first direction, the secondary correction module (130) comprising a secondary control member (131) integral with a secondary control stem (133), which operates a second function corrector (12) of the horological movement (1), the cylindrical body (110) receiving the primary correction module (120) and the secondary correction module (130).

A timepiece case including a middle (20) receiving a horological movement (1) having at least one function corrector (10, 12) for carrying out various functions of activating, selecting, resetting and/or correcting a piece of information derived from the current time of the horological movement (1). The middle has a correction member (100), and a control stem (120) moving in translation within the cylindrical body of the correction member. The correction member (100) is mounted such that it slides in the middle (20) between a plurality of stable positions, each of the stable positions modifying the position of the end (122) of the control stem (120) facing the horological movement (1).

An electronic device, such as a watch, has a crown assembly having a shaft and a user-rotatable crown. The user-rotatable crown may include a conductive cap that is mechanically and electrically coupled to the shaft and functions as an electrode. The conductive cap may be coupled to the shaft using solder or another conductive attachment mechanism. The shaft may electrically couple the conductive cap to a processing unit of the electronic device. One or more additional electrodes may be positioned on the exterior surface of the electronic device. The conductive cap is operable to be contacted by a finger of a user of the electronic device while another electrode is positioned against skin of the user. The processing unit of the electronic device is operable to determine a biological parameter, such as an electrocardiogram, of the user based on voltages at the electrodes.
