Abstract: The oscillating weight includes a primary oscillating weight (10) secured to a drive arbor (6) and at least one secondary oscillating weight (20), which is mobile relative to the primary weight to cause the initial impulse. The secondary weight (20) is formed by a part assembled to the primary weight (10) from the exterior, while being able to have a travel between two stop members (12a, 12b) of a guide means (14, 18) located on the periphery of the primary weight (10).

Abstract: The timepiece includes a stationary outer case (1) in which a pivoting inner case (10) is hinged in an inclined position via the action of a spring. The locking/unlocking mechanism is characterized in that it is formed by a mobile element of the external part that can be manipulated in the plane of the timepiece such as a rotating bezel (20) of the inner case (10) including a lug (22) that is engaged in a groove (2) of the outer case (1).

Abstract: The links (1) are formed by a set of parts (3, 4, 6, 9, 15) including at least two caps (3, 4) including, on the one hand, means for assembling (13, 14, 15) their feet (3b, 4b) to hold, between their heads (3a, 4a) a decorative casing element (9), and on the other hand, locking means (6, 16) at the junction of their feet (3b, 4b) for immobilising each link (1) on the connecting member. The preferred embodiment includes a rigid tube (15) assembling the feet (3b, 4b) and holding a deformable insert locking the connecting member.

Abstract: The watch strap includes a first strand provided with a buckle with a tongue and a second strand for engaging in the buckle. To allow a rough adjustment of the length of the strap, the first strand includes a plurality of transverse orifices and central holes which are distributed from its free end. It is thus possible to cut the strand on a section that passes through one of the central holes, then to fit the buckle and tongue onto the new free end of the strand. This strap can be manufactured in one size for all wrist sizes.

Abstract: The link element (12) includes a strand (14), which extends longitudinally in a horizontal plane, and a front end which (22) includes a device for attachment to a watch (10). The attachment device includes a casing (24), which is secured to the front end (22) of the strand (14), and two coaxial securing pins (26) of transverse axis (A) which are received in two associated lateral housings (28) of the casing (24). A free end of each pin (26) is pivotally received about the transverse axis (A) in one of the two opposite orifices of the watch (10). The casing (24) includes a bottom plate (32) and a top back plate (34), The front end (22) of the strand (14) includes a holding pin (44), which is fitted vertically into a opening (46) of the bottom plate (32). The top back plate (34) is secured to the bottom plate (32) trapping the front end (22) of the strand (14) such that the casing (24) is secured to the strand (14).

Abstract: The invention concerns a timepiece including a middle part (4) and a bezel (6) capable of rotating on the middle part (4), the bezel (6) and the middle part (4) delimiting between them an annular chamber (38) in which there is arranged a sealing gasket (40) with a U-shaped profile. A compression member (42) such as an O-ring type joint with a smooth external surface is housed in the sealing gasket (40).

Abstract: The watch with a metallic case including an electronic module for storing data, which is mounted in an external cavity in the back cover of a case. The module can communicate via broadcast signals with a read and/or write apparatus for said data. The module includes a base on which are mounted an integrated circuit chip having at least two bumps and a coil acting as a transmission and/or reception antenna. The coil is formed by an electrically conductive wire having two ends respectively connected to said bumps of said integrated circuit chip. The coil surrounds a space in which said chip is placed. The dome-shaped base of the electronic module is a metallic element that conducts magnetic flux to insulate the module coil magnetically from the metallic case during data communication between a read/write apparatus and said module. The base of the module can be covered by a protective cover.

Abstract: The oscillating weight includes a primary oscillating weight (10) secured to a drive arbour (6) and at least one secondary oscillating weight (20), which is mobile relative to the primary weight to cause the initial impulse. The secondary weight (20) is formed by a part assembled to the primary weight (10) from the exterior, while being able to have a travel between two stop members (12a, 12b) of a guide means (14, 18) located on the periphery of the primary weight (10).

Abstract: The watchcase includes a middle part (3) closed by a back cover (5) delimiting a housing (7) provided for receiving a watch movement (9) including at least one off-centre display (10, 12). The external surface is entirely covered by a cover-bezel (1) rotatably mounted in the plane of the case on an axis (15) located at the centre of the case and it includes at least one aperture (20) having the same contour as the display (10, 12) and able to occupy a first position in which said display (10, 12) is visible, and another position in which said display (10, 12) is concealed.

Abstract: The wristband with a clasp (1) includes electrical connection means (2) for connection to at least one electric or electronic component (23). These electrical connection means include an electric connector (2) 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 (6) and bellows (5) when the clasp is in the closed position.

Abstract: The wristwatch includes a case (3) carrying at least one watch movement and at least one display (7, 17) for the current time and for other time related or non-time related information. The case (3) is fixedly or rotatably mounted at the end of an additional strand (10), made in one or more parts (14, 16, 18), comprising locking/unlocking means (19, 29) allowing the watch to be unfolded inside the hand.
