Abstract: In a timepiece with a striking mechanism, for example a minute repeater watch, in order to prevent the control stem (9) inadvertently setting the time during operation of the striking work and causing damage, an uncoupling device is inserted in the time-setting train (17), and is controlled via a mobile part of the striking mechanism. The uncoupling device includes an intermediate motion wheel (19) that can be moved, for example axially, from a rest position in which it is meshed with the castle wheel (16). Said mobile part of the striking mechanism is preferably the strike barrel arbour (46), carrying a rotating cam (56) with a spiral profile. At the start of actuation of the striking mechanism, the cam pushes a lifting lever (60), which raises a strip (25) controlling the vertical movement of the intermediate motion wheel (19).

Abstract: The invention concerns a corrector device for a timepiece for correcting a piece of information provided by an indicator mechanism (46), the timepiece comprising a case (1) delimiting a volume (8), the device being characterised in that it includes a control lever (14) located outside the volume (8) of the case (1) and able to be actuated by a user, and an actuating lever (16) located inside the volume (8) of the case (1) and cooperating with the indicator mechanism (46) providing the information to be corrected, the control lever (14) and the actuating lever (16) being connected to each other by a stem (20).

Abstract: The hinging device (1) for pivotably attaching the links of a bracelet includes a bar (5) comprising at at least one of its ends (8) a hole (9) provided with an inner thread (10), and a screw (11) whose thread is engaged in said inner thread. The bar and the screw are provided with means (14 to 17) allowing an end portion (18) of the bar (5) to rest radially on a portion (19) of the head (13) of the screw (11) to tighten said screw in said bar.

Abstract: The invention concerns a method of setting a plurality of stones each having a culasse, a crown and a girdle in a metal support element including the steps of: milling a groove on a first face of the support element; piercing from a second face of the support element, opposite to said first face, a plurality of holes each having a diameter substantially corresponding to the diameter of the girdle of the stone that it will receive, such that each hole opens into said groove and the bottom of each hole forms a support wall for the crown of the stone; forming grains in the second face of the support element in proximity to the support walls; setting the stones in place in the holes such that the crown of each stone abuts against the support wall of the hole thereof; and pushing the grains against the culasse of each stone in order to fix the stones in said support element.

The bar and the screw are provided with means (14 to 17) allowing an end portion (18) of the bar (5) to rest radially on a portion (19) of the head (13) of the screw (11) to tighten said screw in said bar.

Abstract: The invention concerns a manual control device for a watch including a bolt sliding on the external surface of a watch case, in particular to set a repeater mechanism, said bolt being connected through an opening arranged in said watch case to a sliding block controlling the desired function, said device further including a sealing gasket arranged around said opening and control means associated with said bolt, said control means allowing said device to pass from a first state, called the rest state, in which the bolt is locked with respect to the case and said gasket is compressed, to a second state, called the setting state, in which the bolt is unlocked and said gasket is not compressed, characterised in that said sealing gasket is arranged to be applied around said opening between said bolt and the external surface of the case and in that the control means include an articulated lever provided with an eccentric portion, said lever allowing said device to pass from the setting state to the rest state and v

Abstract: This watch case includes a caseband (1), a detachable bezel (4) and bayonet means (8,9,10,11,12,13) for interlocking the bezel onto the caseband. Blocking means (6) are interposed between the bezel and the caseband when a predetermined rotation angle has been effected by the bezel, this in order to prevent any rotational movement of the bezel. Such blocking means include manual grasping means (7) enabling retraction of said blocking means, then disengagement of the bezel from the caseband by rotation initially and then translation.
