Abstract: A watch and a method of ultrasonic welding a bezel to the watch at a middle part. The watch includes: a middle part which, with a crystal, delimits a watch case, the crystal being bonded to a shoulder arranged in the watch middle part; and a bezel ultrasonically welded both to the crystal and to the watch middle part.

Abstract: The invention concerns a timepiece including a case, formed by a middle part 5 closed by a back cover and by a crystal 9, said crystal 9 being supported on a bearing surface of the middle part 5, parallel to said back cover, said case forming a housing in which an electronic module 13 is placed; said timepiece further includes a display module fixed to the crystal 9, the electronic module 13 and the display module include an identical number of connection points so that electrical connection means can connect the connection points of the electronic module 13 to the connection points of the display module in pairs.

Abstract: A wristwatch with capacitive touch zones including a case made of a non electrically conductive material, the case including a housing in which a battery is housed and which is closed by an electrically conductive battery cover. The electrically conductive battery cover is mounted on the watch case with interposition of an electrically conductive sealing gasket between the battery cover and the battery.

Abstract: Method of ultrasonic welding a watch crystal, the watch including a middle part which, with the crystal, delimits a watch case, the crystal including a top face oriented towards the user and an opposite bottom face oriented towards the watch cases, a digital display device being fixed to the bottom face of the crystal, a printed circuit board being disposed inside the watch case, underneath and remote from the digital display device, the digital display device being electrically connected to the printed circuit board by means of a zebra electrical connector, wherein, as the crystal is abutting on a shoulder arranged in the middle part, the ultrasounds are directed onto the shoulder to melt the shoulder and to lower the level of the crystal in the direction of the printed circuit board, so that the zebra connector is compressed between the digital display device and the printed circuit board.

Abstract: The movement (10) includes at least one display ring (12, 14) which is rotatably mounted on a bottom plate (16) and which carries markings that will appear in a display zone (22). The ring (12, 14) is fitted with an inner peripheral toothing (24, 26) which cooperates with drive means (20) and which cooperates with a jumper spring (32, 34). The jumper spring (32, 34) is drawn towards the radial abutment position by an elastic return element (40, 42). A holding plate (48) is secured on the bottom plate (16) so as to retain the jumper spring (32, 34) axially. The holding plate (48) is secured on the bottom plate (16) by a bayonet type assembly. The holding plate (48) includes at least one winding member (58) which cooperates with the stop device (32, 34) during the pivoting of the holding plate (48) from the non fixed angular position thereof to the fixed angular position thereof, so as to arm the associated elastic return element (40, 42).
