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.

The stem-crown of a water-resistant watch case includes a tubular stem inserted into a tubular opening of a middle part of the watch case, and a crown including a first portion connected in part to the stem and a second handling portion. The first portion includes an annular contact surface inclined at less than 90° with respect to a longitudinal central axis of the stem-crown starting from the first portion towards the outside of the second portion. In a rest position, the first portion is in contact against an annular receiving surface of the middle part of complementary shape to one end of the tubular opening towards the outside. The crown further includes a washer under a bearing part of the first portion and contacting the stem, being configured to bear in an annular slot of the middle part between the tubular opening and the annular receiving surface.

An electronic timepiece includes: a main unit having a reporting unit that reports information to a user; a crown that can be pulled out from and pushed back into a main unit by the user; a sensor that detects a state of the electronic timepiece; and a processor, wherein the processor detects a state of the crown and the state detected by the sensor and switches between a plurality of modes in accordance with the state of the crown, and wherein upon detecting that the crown has been pulled out or pushed back in, the processor causes the electronic timepiece to operate in a state reporting mode in which the reporting unit reports the state detected by the sensor to the user.

A watch case, including an orientable screwed crown including axially movable, a subassembly including a setting body including a pattern, a tube suitable for being axially inserted into a hole of the case and including an axial indexing profile engaging complementarily with a complementary axial indexing profile of the hole, and the indexing profile is a cone of apex angle less than 15°, arranged to engage by friction with the complementary indexing profile of the hole.

A screw-down orientable crown (200) for watch case (100), including a tube (11) that can be axially inserted into a case housing (90), and a handling body (1) including a pattern (19) and a relief (15) extending axially and, in the coupled position, cooperating for indexing the pattern (19) relative to the case (100) with a complementary relief (55) that a fixed pipe (5) includes which is pushed back from the body (1) by a spring (12), and including an axial stop (3) fixed to the body (1) to axially trap the fixed pipe (5) with a stroke corresponding to the deformation of the spring (12) to enable the disconnection, by a compression of the body (1), between the relief (15) and the complementary relief (55), which relief (15) is carried by a trunnion (4) integral with the body (1) and which is inside the fixed pipe (5).

A shock-proof device (200) for a movement configured to allow the movement of the horological movement (210) along at least three degrees of freedom. The shock-proof device (200) includes at least one damping element (230) configured to damp the shocks of the horological movement (210) and a crown (100) configured to move between a first position (101) wherein the horological movement (210) is free along at least three degrees of freedom and a second position (102) wherein the horological movement (210) is rigidly connected to the crown (100).

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.
