A watch whose watch case includes a case middle and a rotating bezel provided with a bezel locking system. The system includes a rotating crown secured to an arbor, the arbor being arranged inside a radial hole in the case middle. By rotating the crown, the user can screw or unscrew the arbor with respect to the hole. The arbor includes a frustoconical section which interacts with a pin mounted perpendicularly to the arbor and returned towards the arbor by a spring. Screwing the arbor into the hole will cause the frustoconical section to push the pin into a receiving space provided on the lower surface of the bezel, which locks the bezel. Unscrewing the arbor automatically releases the pin from the receiving space by the return force exerted by the spring. The crown can include a helium valve mechanism.

The present invention concerns a portable object including a case () and a bracelet or strap (). The case includes a middle part () from which two pairs of horns () extend, the horns of each pair being connected by a guide element () defining a space in conjunction with the middle part. The portable object includes securing means () including a locking part (') inserted in each end () of the bracelet or strap and at least one groove () located on the middle part (). The securing means () is arranged to enable each end of the bracelet or strap to be inserted in the space defined by the middle part and the horns of each pair connected by the guide element (), such that the locking part () cooperates elastically with said groove to secure said bracelet or strap to the case in a simple manner.

Portable object with an interchangeable bracelet or strap

The oscillating weight includes a primary oscillating weight () secured to a drive arbor () and at least one secondary oscillating weight (), which is mobile relative to the primary weight to cause the initial impulse. The secondary weight () is formed by a part assembled to the primary weight () from the exterior, while being able to have a travel between two stop members () of a guide means () located on the periphery of the primary weight ().

The wristband with a clasp () includes electrical connection means () for connection to at least one electric or electronic component (). These electrical connection means include an electric connector () arranged in one part of the clasp connected to one end of a wristband strand. The connector is of the universal serial bus type so as to be able to be connected, when the clasp is in the open position, to a connector of complementary shape of an electric apparatus, such as a computer station for carrying out energy and/or data transmission with the electric or electronic component. The connector is protected by a fastening piece () and bellows () when the clasp is in the closed position.

Bracelet with clip comprising electrical connection means

The wall of a case includes a U-shaped recess with two through passages ( ) for a control stem ( ) held in a neutral position by a spring ( ) and guided in the outer passage ( ) by an O ring ( ) allowing translation and tilting movements, and in the inner passage ( ) by a contour of oblong shape allowing the end ( ) to close an electric contact ( ) by pressure and two other contacts ( ) by tilting. Application to an electronic timepiece.

Electric device for switching between at least three different contacts

A clasp for a watch wristband includes: two male ( ) and female ( ) joining parts able to be coupled by inserting the male part ( ) into the female part ( ); and a resilient locking mechanism, provided on the male part ( ), locking with a catching mechanism provided on the female part ( ), when the male part ( ) is pushed into an engagement position in said female part ( ) so that it is then impossible to pull outwardly the male joining part ( ), the male ( ) and female ( ) joining parts being able to be uncoupled from each other by pushing the male part ( ) further into the female part ( ) so that the locking mechanism is released from the catching mechanism and the male joining part ( ) can be pulled out of the female joining part ( ).
