摘要:
In order to improve the isochronism of the mechanical movement of a watch, the regulating members comprise at least two tourbillons mounted on a common rotating support driven by one or several barrel springs, such that the tourbillons make an orbital movement around the axis of rotation of the support. The tourbillons are connected by respective going trains to a differential gear, one of whose elements is immobilised by friction.

Clockwork movement for a wristwatch, comprising a kinematic chain including at least one belt (20, 21) for transmitting the movements and/or couples between at least two pulleys. The pulleys are held on the bottom plate or the bridges by ball bearings (151, 161, 171, 181). The movement is rewound by means of linear oscillating mass (14) charging four barrels (15, 16, 17, 18) through a couple distributor (40). The barrels are non-parallel to one another. The back cover is covered by inclined glasses (110, 120, 130) allowing the barrels, the linear oscillating mass and at least certain pulleys to be seen. The regulating organ (51) is removable.

The depth measuring device for a diving watch with a chronograph mechanism, includes a plunger moved by external pressure through a rolling membrane against the action of a return element. The plunger acts on cams belonging to a circular slide mounted in a casing ring. The movement of the slide is transmitted by a gear train to a depth needle and to a dead needle. A pressure sensing device has a sliding plunger mounted inside the winding button. This plunger acts on a control device for automatically starting and stopping the chronograph mechanism. A locking device is used to lock and release the control device and displays a diving flag in the released position. The gear chain displays a safety flag at a predetermined depth. A resetting device allows the various mechanisms and devices to be reset to zero.

摘要:
An article, which can be a watch, a piece of jewelry, a spectacle frame or a leather-ware item, for example, comprising at least one movable decorative element contained inside a housing (15) defined between two walls (5, 10) whose inner faces (5a, 10a) are parallel to one another, at least one (5) of these walls which is externally visible being transparent. This housing (15) encloses movable decorative elements (13, 14) each having an axis of revolution and two guide surfaces (14a, 14b), one of which is convex, respectively adjacent to said inner walls and being arranged to allow the movable decorative elements (13, 14) to move freely in translation and in rotation about their axes of revolution inside the housing (15). The internal faces (5a, 10a) of the housing (15) are dished with a curvature along at least one radius of curvature, which increases the glittering effect by increasing the speed of rotation of the mobile decorative element, such as a diamond.

摘要:
The aim of the present invention is to provide a device whereby various wristwatch movements can be fitted to a single strap, meaning that the watch can be replaced or reversed quickly without opening the strap or case. This aim is achieved by means of a device whereby an object such as a watch case is rendered reversible and interchangeable in a supporting element that is open on one side so that the reversible and interchangeable object can be inserted or withdrawn through said side opening, characterised in that said side opening is sealed by a portion of the reversible and interchangeable object that fits snugly onto the open side of the supporting element, thereby locking same. The device comprises retaining means for retaining the reversible and interchangeable object within the supporting element. It should be noted that in one embodiment of the device, there is no strap (100) and a clip (300) is inserted into portions (202, 203) of the supporting element (200) so that the assembly can be used as an adornment.
摘要:
A writing instrument, notably a pen, comprising a body (1a, 1b) characterized in that this body or a fitted piece comprises at least one housing (6) having a transparent outer wall (7). The height of this housing (6) between its bottom and said transparent outer wall (7) is substantially constant, at least one movable decorative element (9) such as a diamond being movably mounted inside said housing (6), at least one of the dimensions of the movable element perpendicular to said height being substantially less than the corresponding dimension of the housing (6). This movable decorative element (9) is mounted in a support comprising two guide surfaces (10a, 10b) adjacent to the said bottom (6a) and to said transparent wall (7) respectively, these surfaces allowing random movement in translation and in rotation of said decorative element (9) about itself inside said housing (6).
