A timepiece movement includes a photovoltaic cell which is attached to the upper surface of a support plate, preferably by adhesive bonding. On the other side of the cell, on its lower surface, the support plate is provided with a plurality of nuts. An electrical module including a flat surface is attached to the support plate with the nuts. The module is provided with several openings whose position and dimensions correspond to those of the nuts, so that the nuts pass through the openings, allowing the flat surface of the module to be placed in contact with the support plate. The module is secured to the support plate by screws, screwed into the nuts. The connection via the nuts secures the photovoltaic cell to the electrical module and ensures shock resistance, without requiring a lateral support.

Electronic watch with a solar cell

A device for mounting an electrical energy source in portable electronic equipment is provided, including a cavity and a cover configured to close the cavity, the cover including a housing configured to receive the energy source, the cover and the portable electronic equipment having complementary fixing means in order to retain the cover on the portable electronic equipment and to seal the cavity, and the cover including means for retaining the energy source in the housing of the cover.

Device for mounting an electrical source

A motor module includes a stator formed of a main plate of a first thickness on which is mounted a rotor The stator has at each end a receiving zone, the thickness of which is less than the first thickness.

Simplified motor module

An electronic device including a case includes a glass and a back cover, the electronic device including at least one electronic module configured to calculate a current time, to execute plural functions and to provide information relating to the current time and to the functions to a display disposed underneath the glass. The electronic device further including a controller including at least one contact area allowing a user to act on the at least one electronic module, the at least one contact area being monitored by the electronic module at a scanning frequency.

Method for managing operations on an electronic device

A portable object including a case in which at least one electronic module is placed, the at least one electronic module configured to execute plural functions and to provide information relating to the functions to a display, the electronic device further including a controller including at least one contact area allowing a user to act on the at least one electronic module, each function being associated with a predetermined time threshold.

Method of operating an electronic device

A watch intended to be removably mounted on a support, including a watch case and an independent removable attachment device arranged to retain the watch case in an opening provided in the support, the watch case including an upper portion, on the dial side, and a lower portion including a back cover, the lower portion being arranged to be housed inside the opening in the support and being of smaller dimensions than those of the upper portion to form a flat peripheral shoulder. The attachment device includes a flange having a central opening arranged to receive the lower portion of the watch case and an inner rim delimiting the central opening, the inner rim being arranged to be housed inside the opening in the support. The inner rim includes a locking device for locking the attachment device on the lower portion of the watch case.

Watch intended to be mounted on a removable support

A portable electronic object is provided with a case including a middle part closed by a back cover and by a glass and a bezel fixed to the middle part. The case contains at least one electronic module formed of a printed circuit board to which is fixed at least one microcontroller sending information to a display. The object further includes a tactile control including at least one base element on which there is arranged at least one electrode. The electrode is electrically connected to the microcontroller by a conductive path.

Portable tactile electronic object

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.

Watch including a bezel and method of attaching such bezel

The invention concerns a timepiece including a case, formed by a middle partclosed by a back cover and by a crystal, said crystalbeing supported on a bearing surface of the middle part, parallel to said back cover, said case forming a housing in which an electronic moduleis placed; said timepiece further includes a display module fixed to the crystal, the electronic moduleand the display module include an identical number of connection points so that electrical connection means can connect the connection points of the electronic moduleto the connection points of the display module in pairs.

Method of aligning a crystal relative to the middle part of a timepiece

A display module for a timepiece, including a dial, on a lower face of which is secured a digital information display device, a solar cell, and a plate. The solar cell is accommodated in the plate such that the solar cell is underneath and at a small distance from the dial. The assembly formed by the dial and the digital information display device is disposed atop the solar cell.

Display module for a timepiece including a solar cell

A lighting system for an information display device, the lighting system including a light guide including at least one area into which the light produced by a light source is injected, the light guide also being used as a guide element for at least one electrical connector for the electrical connection between the information display device and an electronic control circuit of the information display device, wherein the light guide is coated, in the light injection area, with a layer of electrically non-conductive material which absorbs light.

Light guide for lighting an information display device

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.
