A timepiece according to an embodiment enables a crown to be rotated even when it is locked, using a structure that does not cause constraints of design. The timepiece includes an outer case having a movement therein, the outer case having a crown hole through a portion thereof, an engagement member connected to the outer case, and a crown. The crown includes a shaft part inserted into the crown hole and connected to the movement, an operation part holding the shaft part movably along an axial direction of the shaft part and enabling the shaft part to rotate in a circumferential direction, and an engagement part disposed between the engagement member and the operation part and restricting movement of the operation part in the axial direction when engaged with the engagement member, the engagement part rotatably holding the operation part whether or not engaged with the engagement member.

An electronic watch may include a housing defining a side wall having a through-hole and a crown assembly including an actuation member. The actuation member may include a crown shaft extending through the through-hole and having an exterior portion defining an input surface and a crown ring coupled to the exterior portion of the crown shaft and electrically isolated from the crown shaft. The crown assembly may further include an optical encoder component attached to the actuation member and defining a group of optical features. The electronic watch may further include an optical detector configured to detect rotation of the crown assembly by detecting motion of the group of optical features and an electrocardiograph sensor comprising a sensing component. The sensing component may be conductively coupled to the actuation member via a conductive path at least partially defined by the crown shaft.

A watch case having a locking system for at least one control element of a timepiece, the locking system including a manipulable element, a locking element for the at least one control element, and a kinematic link linking the manipulable element to the locking element, the locking system being arranged on the outside of a chamber (63), more particularly on the outside of a water-resistant chamber, defined by the case, the locking element being rotatably mounted, more particularly rotatably mounted about a second axis (A1) of the at least one control element.

A watch case having a locking system for at least one control element of a timepiece, the locking system including a manipulable element, a locking element for the at least one control element, and a kinematic link linking the manipulable element to the locking element, the locking system being arranged on the outside of a chamber (63), more particularly on the outside of a water-resistant chamber, defined by the case, the locking element being rotatably mounted, more particularly rotatably mounted about a second axis (A1) of the at least one control element.

Method of assembling a timepiece comprising a watch movement and a water-resistant case, the method comprising: a first stage of closing the case by fitting and securing a first case element, more particularly a back, and then a second stage of closing the case by actuation of a second case element, more particularly a stem, in particular a winding stem or a valve stem or a push-button stem, the second case element being mobile between a first configuration, in which a fluid communication between the interior of the case and an environment outside the case is permitted, and a second configuration, in which the fluid communication between the interior of the case and the environment outside the case is limited, the second stage of closing being an actuation of the passage of the second element from the first configuration to the second configuration.

An electronic device has a housing and a rotatable and translatable input mechanism. The housing has an aperture and the rotatable and translatable input mechanism has a shaft positioned at least partially within the aperture and a manipulation structure coupled to the shaft. The manipulation structure may be manipulated to rotationally and translationally move the shaft to provide rotational and translational input to the electronic device. A compressible seal is positioned in a gap between the housing and the rotatable and translatable input mechanism. The compressible seal may resist and/or prevent passage of contaminants into the aperture and/or obscure one or more internal components. The compressible seal may be configured to collapse or bend when the rotatable and translatable member translates.
