Abstract: Disclosed is a timepiece component including at least one housing intended to receive at least one precious or non-precious stone and including at least one first end, referred to as the setting end, and a rail. The rail is located on the periphery of the housing, and is arranged to allow the stone or stones to be inserted into the rail at the first end of the housing, such that the stone or stones can slide in the rail along the longitudinal axis of the housing, and to hold the stone or stones once inserted into the rail in a direction perpendicular to the longitudinal axis of the housing.

Abstract: Light weight composites with high flexural strength comprise epoxy foam sandwiched between two layers of facing material have high strength and low weight and can be used to replace steel structures. The facing layer may be fibrous material especially glass or carbon fibres, the facing material is preferably embedded into the epoxy matrix. Alternatively they may be matching box structures or concentric metal tubes. The sandwich structures may be prepared by laying up the fibre; coating and/or impregnating the layer with epoxy resin, laying a layer of heat activatable foamable epoxy material, providing a further layer of the fibrous material optionally coated and/or impregnated with epoxy resin on the foamable material and heating to foam and cure the epoxy materials. Alternatively they may be formed by extrusion of the foamable material between the surface layers.

Abstract: A device for finely adjusting the length of a bracelet inserted between two elements of the bracelet and includes an outer part attached to one, an inner part attached to the other and to slide in the outer part parallel to the longitudinal direction of the bracelet, causing the length of the bracelet to be varied, and a stop arranged to limit the travel of the inner part relative to the outer part so the bracelet cannot be extended beyond a maximum length. The outer part includes a wall having an immobilization hole on its inner side. The inner part includes a pivoting lever with a first end biased by a spring toward the outer part wall, permitting the first end to engage the immobilization hole, immobilizing the inner part relative to the outer part. The inner part has a control member permitting manual control of the lever.

Abstract: Disclosed is a mechanical wristwatch including a case having a middle, a back cover and a bezel, a vibration-generating device for generating vibrations which are intended to produce at least one sound, which is accommodated in the case, a vibration-amplifying for amplifying the vibrations generated by the vibration-generating device, and a membrane arranged to receive the amplified vibrations and generate a sound from the inside to the outside of the wristwatch. The vibration-generating device is a rotary element having a reading surface including at least one groove arranged to generate sounds. The wristwatch also includes a unit for rotationally driving the rotary element, an actuator for such unit, and a transmission member arranged to cooperate with the rotary element to transmit, to the vibration-amplifying device, the vibrations generated by the groove during rotational movement of the rotary element.

Abstract: Disclosed is a timepiece including a case, a movement and a vibration-generating device intended to produce a sound, the latter two accommodated in the case, a device for amplifying the vibrations from the vibration-generating device, and a membrane receiving the amplified vibrations and generating a sound to outside the timepiece. The vibration-amplifying device includes a lever pivotally mounted on a support in a pivoting plane non-parallel to the plane of the membrane and actuated by a transmission member cooperating with the vibration-generating device to transmit the vibrations to the lever, the lever being integral with the membrane at least translationally in the pivoting plane so a movement of the transmission member, generated by vibration of the transmission member linked to the vibration-generating device and transmitted to the membrane by way of the lever actuated by the transmission member, generates an amplified movement of the membrane for an amplified sound.
