Embodiments are directed to a smartwatch including a housing that at least partially defines an internal volume, and a touch-sensitive display positioned at least partially within the internal volume. A front cover can be positioned over the touch-sensitive display and can define a front exterior surface. A seal can be positioned between the housing and the front cover and configured to transition between an uncompressed state and a compressed state in response to an increase from a first external pressure on the front cover to a second external pressure. In the uncompressed state, the seal has a first density and is air-permeable allowing an internal pressure of the internal volume to equalize with external air at the first pressure. In the compressed state, the seal has a second density, greater than the first density, and is configured to inhibit ingress of water at the second pressure.

An orientable valve including a device for adjusting the angular orientation of the valve head with respect to the watch case, wherein the device for adjusting the angular orientation of the valve head includes a friction ring disposed between the valve head and the upper step, the friction ring rotates integrally with the shaft and is free in translation with respect to the shaft, the friction ring has a cylindrical external friction surface in friction contact with an internal wall of the tube, and wherein the shaft includes, in its distal portion, a device for actuating the latter in rotation making it possible to pivot the valve to adjust the angular orientation of the valve head.

A display apparatus includes a protecting plate formed of a material which transmits light, light transmitting type solar panel which is positioned below the protecting plate, a display below the light transmitting type solar panel, which is provided in contact with the light transmitting type solar panel, and which includes a display region which can be viewed from outside. An air layer which is positioned between the protecting plate and the light transmitting type solar panel, and at least one light reflection prevention layer on at least one of a first surface of the protecting plate facing the air layer and a second surface of the light transmitting type solar panel facing the air layer, wherein the display region of the display can be viewed from outside through the protecting plate, the at least one light reflection prevention layer, the air layer, and the light transmitting type solar panel.

A closing/opening system for a case of a timepiece is defined particularly in first and second parts of the case. The system includes a device for producing a mechanical connection, particularly a bayonet connection between these first and second parts and a device for creating a friction torque between these first and second parts. The device for creating a friction torque includes tightening faces to cooperate with one another when closing/opening the case and which are defined in the first and second parts. The system further includes a tightening element in one of these two tightening faces. The tightening element generates a constant friction torque during a course of travel of one of the two parts relative to the other when closing/opening the case of the timepiece.

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.

A water-resistant watch case of a diving watch, includes at least one back mounted on a lower side of a middle part, and a crystal mounted with a fastening gasket on an upper side of the middle part. The back includes an annular bearing surface for coming into contact with an inner annular surface of the middle part of a shape complementary to the bearing surface during mounting of the back on the middle part. The annular bearing surface and the inner annular surface are inclined towards the inside of the watch case at a determined angle less than 90 relative to a central axis perpendicular to a plane of the watch case so as to distribute stresses between the back and the middle part due to the water pressure during a dive. The annular bearing surface and the inner annular surface are conical in shape.
