A multifunction correction device () for a case () of a timepiece including a horological movement () having at least one function corrector () for carrying out various functions of activating, selecting, resetting and/or correcting a piece of information derived from the current time of the horological movement. A control member () is capable of moving in rotation about the axis of revolution (X-X) of a control stem () between a plurality of angular positions and a protrusion () is configured such that the rotation of the control member () modifies the angular position of the protrusion () about the axis of revolution (X-X) and relative to the horological movement ().

A timepiece case including a middle () receiving a horological movement () having at least one function corrector () for carrying out various functions of activating, selecting, resetting and/or correcting a piece of information derived from the current time of the horological movement (). The middle has a correction member (), and a control stem () moving in translation within the cylindrical body of the correction member. The correction member () is mounted such that it slides in the middle () between a plurality of stable positions, each of the stable positions modifying the position of the end () of the control stem () facing the horological movement ().

A horological resonator mechanism, including a structure and an anchoring unit from which is suspended at least one inertial element arranged to oscillate along a first degree of freedom in rotation RZ about a pivoting axis extending along a first direction Z, the inertial element being subjected to return forces exerted by a virtual pivot including a plurality of substantially longitudinal elastic strips, each fastened, at a first end to the anchoring unit, and at a second end to the inertial element. Each elastic strip is deformable essentially in a plane XY perpendicular to the first direction Z. The anchoring unit is suspended from the structure by a flexible suspension arranged to allow the mobility of the anchoring unit along a plurality of degrees of freedom including at least two in the plane XY, along a direction X and along a direction Y orthogonal to the direction X.

A fixing device for adjusting the clearance of a balance. At least one fixing device including at least one stud holder, at least one bearing body, at least one support member and at least one holding member. At least one bearing body is configured to move relative to at least one stud holder so as to fix the adjustment of the clearance of the balance and at least one support member is configured to press at least one bearing body against at least one stud holder before being held by at least one holding member.

A vertical type uncoupling device, in particular in an automatic watch winding mechanism that includes an oscillating mass and a gear train connecting the oscillating mass to a barrel (), wherein a gear train includes a direction reverser device (), a reduction gear () and the uncoupling device (). The uncoupling device includes two coaxial wheels () that can be coupled in rotation in one direction owing to respective Breguet toothings () arranged on the opposite flanks of the wheels. The coaxial wheel (), which is mobile in the axial direction, is secured to a sliding arbour (), which is mounted so as to rotate and slide in fixed bearings (). A return spring () includes an elastic strip that abuts against one end of the sliding arbour () to tend to engage and keep meshed the Breguet toothings. This design reduces friction and saves space. Other applications of this type of uncoupling device in a watch movement are described.

The oscillating weight () is for automatically winding a timepiece movement; it pivots off-center relative to the center of the movement and is made of a single heavy material. The weight () is carried by a shock absorber () that takes the form of a plate (), one end of which is secured to the weight and the other end of which is secured to a tube () arranged to rotate about an arbour () forming the axis of rotation of the weight.

The invention comprises a chronograph watch including a chronograph mechanism. The chronograph mechanism includes a chronograph train (), and a counter mechanism () kinematically connected to the train (). The counter mechanism () further includes first and second wheel sets () respectively provided with first and second display members (), wherein the first wheel set () is angularly positioned using positioning members () so as to rotate in steps, and the second wheel set () is angularly positioned by the first wheel set ().

Chronograph watch

The dial () of the watch is fitted with an indicator (), preferably with a hand (), which displays the function fulfilled by a control crown (), respectively, in each axial position of the crown, including a highly water resistant position in the case of a screwed-in crown. The indicator is controlled by axial movements of a sleeve () secured to the crown, via a transmission mechanism () including a slide block () that is mobile parallel to an axis of rotation () of the crown. The hand is secured to a pinion () meshed with a rack () arranged on a slide block. The slide block includes a flexible part () between a back part that slides in a groove (), and a front arm () provided with a lateral finger () engaged in an annular groove of the sleeve. This transmission is compact and facilitates assembly and removal.

The invention concerns a timepiece including a dial () fitted with an aperture () behind which is mounted a moon phase disc () driven in rotation by a moon phase train (). According to the invention said disc () is mounted so as to move in rotation about a fixed sun pinion (). Moreover, two planetary wheels (), secured in rotation to representations of the moon (), are mounted so as to move in rotation on the disc (), at least indirectly meshed with the sun pinion (), so as to form a planetary train with the sun pinion ().
