A wearable object including a middle of a case, a bracelet, and a fastening system for removably securing the bracelet to the middle, the middle including two longitudinal cavities configured to form a slide-bar and receive a hooking head of the bracelet of complementary shape and configured to cooperate by sliding. The fastening system includes elastic casing elements to bolt the axial movement of the hooking head inside the longitudinal cavity, the elastic casing elements including: a rigid bolting protrusion, arranged on an inner wall of each of the longitudinal cavities, cooperating with; two obstacles arranged in the vicinity of an elastic portion of the hooking heads, the obstacles delimiting an inter-obstacle space designed to receive the bolting protrusion and form locking elements of the bolting protrusion; the elastic casing elements being configured to elastically distort the elastic portion of the hooking head during the insertion of the bracelet.

The present invent concerns a portable object comprising at least a middle part and a back cover for confining an electronic module, said electronic module including a plate provided with a housing arranged for receiving an electrical energy accumulator, said electronic module including at least one circuit with at least one electrical contact area, and a connecting contact member for providing an electrical connection between said accumulator and said at least one contact area, said contact member being elastically deformable.

Device for securing a cell battery with improved contact

A structure for a timepiece includes a middle part and a back cover that confines an electronic or electrical module. The module includes a plate, at least one circuit with at least one electrical contact area, and a connecting contactor. The plate includes a compartment that is arranged to receive an electrical energy accumulator. The connecting contactor provides an electrical connection between the accumulator and the at least one contact area. The contactor is rigid and includes an elastic return that tends to return the contactor to a rest geometry. The contactor includes at least a first arm and at least a second arm that together form a clamp that presses the circuit and the accumulator towards each other.

An assembly including a watch dial and a bottom plate, the bottom plate being delimited by an upper peripheral rim which is extended downwards by an external peripheral surface, the watch dial being secured to the upper peripheral rim of the bottom plate via at least first and second securing mechanisms, wherein the first securing mechanisms includes a boss provided on the external peripheral surface of the bottom plate, the dial having a peripheral edge via which the dial is held between the head of a nail or a screw and the upper peripheral rim of the bottom plate, the head of the nail or screw being extended by a shank which is housed in the boss of the bottom plate.

Date mechanism for a timepiece such as a wristwatch including two superposed respectively lower () and upper () date rings, whose surface is divided into a plurality of sectors, the upper ring () including sixteen sectors, fifteen of which respectively bear fifteen successive markings of a cycle of 31 positions, and the sixteenth of which is an extra sector having an open or transparent aperture (), whereas the lower ring () includes seventeen sectors, sixteen of which bear respectively the other sixteen markings of the cycle of 31 positions, and the seventeenth of which is an extra sector, each of said rings cooperating with drive means such that the markings appear successively in a display zone () the date mechanism further including a jumper-effect stopping device () able to stop each ring () in any desired position, the date mechanism being characterised in that one location on the upper ring () and one location on the lower ring () is provided with a thinned tooth () and (), located between two successive teeth () or () of the toothing of the ring () or () concerned, the position of the drive means with respect to the toothing of the rings () being such that when a ring () or () has its extra sector at the location of the display zone (), the thinned tooth () or () is located opposite the drive means such that said drive means only drive the other ring, the thinned teeth () not disturbing the movement of the drive means and allowing the stopping device () to be constantly housed between two successive teeth () or () of each of the rings ().

Timepiece with a date mechanism comprising two superposed date rings

Date mechanism for a timepiece such as a wristwatch including two superposed respectively upper () and lower () date rings, whose surface is divided into a plurality of sectors, the upper ring () including sixteen sectors, fifteen of which respectively bear fifteen successive markings of a cycle of 31 positions, and the sixteenth of which is an extra sector having an open or transparent aperture (), whereas the lower ring () includes seventeen sectors, sixteen of which bear respectively the other sixteen markings of the cycle of 31 positions, and the seventeenth of which is an extra sector, each of said rings () cooperating with drive means such that the markings of the lower ring appear successively in a display zone (), the date mechanism being wherein each ring () includes two peripheral toothings extending along two stepped, respectively upper and lower rows, the teeth () of the upper and lower rows of the upper ring () being superposed, whereas the teeth () of the upper and lower rows of the lower ring () are staggered, one location () of each of the toothings of the upper () and lower () rings being tooth free, and in that said date mechanism further includes a correction device, the position of the drive means with respect to the upper and lower toothings of the respectively upper () and lower () rings, and the position of the correction mechanism with respect to the lower and upper toothings of the respectively upper () and lower () rings being such that when the upper ring () has its extra sector at the location of said display zone (), the drive means and the correction device are located respectively opposite the tooth free location () of the toothing of the upper row and that of the lower row of the upper ring, and vice versa.
