A bracelet with links articulated to each other like a hinge, includes first links provided with a male hinge part pierced by a first through hole, second links provided with a female hinge part pierced by second and third through hole, the first, second and third holes forming an alignment when a male hinge part is engaged in a female hinge part. The bracelet further includes pins occupying the hole alignments, and axial locking elements for the pins formed of a first radially elastic tube and a second tube, axially locked in the first through holes, the pins being driven inside the first slit tubes. The first and second tubes include an annular end via which the tubes are secured to each other so as to preserve the radial elasticity of the first tube.

Bracelet with articulated links

The push-button control device for a watch includes a push-button stem () inserted via a bottom end into an orifice () of a watchcase and a button () mounted on a top part () of the stem () outside the watchcase. The stem can slide axially between a rest position and an active position against a return member () to control at least one function of the watch. The control device is characterized in that the top part () of the stem includes an annular groove delimited by two parallel shoulders () perpendicular to the axis of the stem, and in that the button () includes an annular base () that is engaged in the groove so as to be held between the two shoulders () in the axial direction and centred with some play by the bottom of the groove such that the button () is free to move off-centre relative to the axis of the stem () while remaining secured thereto.

Push-button control device for a watch

In an electronic apparatus worn on the wrist such as a diver's wristwatch or an altimeter, a pressure sensor () is mounted from the exterior in a housing (), located in one flank () of the case () of the apparatus and closed by a cap () provided with at least one orifice () for transmitting the ambient pressure towards said housing. The sensor is mounted in the housing by means of a sealing gasket (). A protective screen () is placed between the central wall () of the cap and the exposed surface () of the sensor, in order to prevent solid bodies and/or solar light being able to damage the sensor. Preferably, this screen is formed by a perforated plate fixed to the cap and whose holes () are shifted laterally with respect to each orifice () of the cap, such that all of the transmission paths of the ambient pressure from the exterior to the exposed surface of the sensor are sinuous.
