A device for attaching a bracelet or strap to a watch case, the device including, on the one hand, a bar secured to the watch case by a horn, and on the other hand, an insert integral with the end of the bracelet, wherein the bar and the insert are complementary to interlock with each other forming a removable assembly to make the bracelet interchangeable. The insert includes a movable pivot mounted in the insert and arranged to engage in a corresponding hole of the horn, the device having handling device integral with the movable pivot in order to move from a first position, in which the pivot is free to move and the strand can be assembled and/or disassembled, to a second position, in which said pivot is stationary in translation and the bracelet strand is locked on the watch case.

Device for attaching a bracelet

A timepiece including a device for opening a cover including a fixed pendant mounted inside a middle part and a movable pendant for sliding within the fixed pendant towards the center of the case, the movable pendant having a guide element for moving along an axial guide groove, then in a circumferential guide groove into which the axial guide groove opens out and which is delimited by a boundary, such that, when the movable pendant is pushed, this movable pendant can be firstly displaced axially, then pivoted by an angle defined by the place at which the guide element abuts against the boundary, the movable pendant having a helical groove which comes into contact with at least one pin arranged with a clearance between the movable pendant and the locking spring and which is axially displaced towards the locking spring when the movable pendant is pushed, then pivoted, such that the pin presses against the locking spring and releases the cover.

Timepiece, in particular a pocket watch, equipped with at least one cover

An annular rotating bezel system to be rotatably mounted on a case middle of a watch case inside which is housed a timepiece movement which extends in a plane, including a rotating bezel, an annular holding ring, a toothed ring, and a spring ring which extends in a plane in which it is capable of deforming elastically along a radius, the spring ring cooperating elastically with the toothed ring, the toothed ring and the spring ring being held in an axial direction perpendicular to the plane of the movement in the bezel by the annular holding ring, either the toothed ring or the spring ring being arranged to be angularly joined to the rotating bezel, and the other being arranged to be angularly joined to the case middle, wherein the spring ring has a thinned portion to increase the flexibility of the spring ring in its plane, the thinned portion having a tooth elastically and radially meshed with the toothed ring.

Annular rotating bezel system comprising a spring ring

An annular retaining ring for a rotating bezel system, intended to cooperate with an external cylindrical surface of a case middle part of a watch case to allow rotation of the rotating bezel on the case middle, the annular ring including a device for guiding rotation of the rotating bezel around the case middle; wherein the annular ring further includes a device configured to brake rotation of the rotating bezel around the case middle and to dampen sound.

Annular retaining ring for a rotating bezel system

An annular rotating bezel system intended to be rotatably mounted on a middle part of a watch case inside which is housed a timepiece movement which extends in a plane, including a rotating bezel, an annular holding ring, a toothed ring, and at least one elastic arm of which a free end is elastically and radially meshed with the toothed ring, said toothed ring and said at least one elastic arm being held in an axial direction perpendicular to the plane of the movement in the bezel by the annular holding ring, either the toothed ring or the elastic arm being arranged to be angularly joined to the rotating bezel, and other being arranged to be angularly joined to the case middle; wherein the elastic arm is formed of a flat strip-spring mounted in a cantilever arrangement in the system.

Annular rotating bezel system comprising at least one elastic arm

An annular rotating bezel system includes a rotating bezel, a toothed ring having a toothing provided with a plurality of teeth regularly distributed over an edge of the toothed ring, and a spring ring which extends in a plane in which it is capable of deforming elastically along a radius. The spring ring cooperates elastically with the toothed ring. The spring ring includes at least two lugs, each lug being configured to be elastically and radially engaged with the toothing of the toothed ring in at least one position of the bezel. At least two lugs are offset from each other by an offset angle, the or each offset angle between two successive lugs having a value different from an integer sub-multiple of 360 degrees, such that, in each position of the bezel, only one lug is elastically and radially engaged with the toothing of the toothed ring.

A timepiece including a case middle, a bezel, rotatably mounted on the case middle, and an actuation member including a cover capable of adopting a retracted position and a deployed position relative to the case middle, the cover being provided with a bearing surface actuatable by the user's finger, wherein the cover includes a shoulder distinct from the bearing surface, the shoulder being intended to cooperate with the bezel when the cover is in the retracted position.

Timepiece with retractable pusher

A timepiece case band including a peripheral shoulder in which an annular rotating bezel system is rotatably mounted. The rotating bezel system is an independent module including an annular bezel, an annular support element, a toothed element, and a spring mechanism cooperating elastically with a snap-fit mechanism, the spring mechanism and the toothed element being axially retained by the bezel and/or the support element. The rotating bezel system further includes a securing mechanism securing the spring mechanism, support element, and bezel to each other.

Rotating bezel system

The invention concerns a timepiece comprising a middle part () closed by a back cover and a crystal, said middle part () comprising a peripheral shoulder () in which a groove () is arranged, said groove being disposed on a surface of the shoulder parallel to the central axis of the middle part (C), said timepiece comprising a rotating bezel system () rotatably mounted on said peripheral shoulder, characterised in that said rotating bezel system includes a bezel ring () provided with at least a first recess () disposed on a surface of the bezel intended to face said groove when said rotating bezel system () is fitted onto the middle part, said rotating bezel system () further comprising a spring means () extending both into said at least one first recess () of the bezel and at the same time into the groove () in the middle part so as to hold the rotating bezel system () on the middle part () of the timepiece.

The piece of jewellery comprises at least two rings () that can nest inside each other and have different diameters. These rings are assembled to each other so as to pivot relative to each other. The piece of jewellery can thus pass from a configuration wherein the rings are tilted to a configuration wherein they are nesting, such that the surface of the smaller ring () is concealed. The piece of jewellery further comprises indexing means () comprising a stud () secured to one of the rings () and which is arranged for cooperating with the edge () of an elongated aperture () made in another ring (), so as to immobilize the rings selectively in a plurality of relative positions.

Piece of jewellery comprising a mobile part

The electronic watch movement components ( ) of the watch are mounted on a flexible printed circuit film ( ), which is then incorporated in the wristband ( ) by overmoulding of an insulating elastomeric material. External elements in the form of cases ( ) are mounted in a sealed manner on the wristband to protect said components and to cover at least a display unit ( ) and an electric power source ( ). Decorative elements ( ) similar to the cases are distributed along the wristband to imitate links. Such a wristwatch may be manufactured at a low cost.
