摘要:
The invention relates to a timepiece with an analogue display, including a timepiece movement (1) provided with a mechanical output, located on an arbour (2) of said movement, and a display assembly (30) provided with at least one time display device (31, 32, 111, 112) driven by said mechanical output, wherein the display assembly is separate from the timepiece movement (1) and linked to a fixed part (10) of said movement (1) by support means which enables said display device to take several different positions around the output arbour (2) of the movement. According to the invention, the support means of the display assembly includes an intermediate support (34, 70, 72, 70′) secured to the fixed part (10) of the timepiece movement (1) and provided with support members (36, 87, 89, 87′, 89′) allowing said at least one display device (31, 32, 111, 112) to be assembled in several positions on the intermediate support (34, 70, 72, 70′).The invention concerns the field of timepiece display members.

The invention concerns 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 (9), wherein said gear train includes a direction reverser device (11, 12), a reduction gear (13, 14, 15, 16) and the uncoupling device (20). The uncoupling device includes two coaxial wheels (17, 7) that can be coupled in rotation in one direction owing to respective Breguet toothings (21, 22) arranged on the opposite flanks of said wheels. The coaxial wheel (17), which is mobile in the axial direction, is secured to a sliding arbour (18), which is mounted so as to rotate and slide in fixed bearings (24, 25). A return spring (26) includes an elastic strip that abuts against one end of the sliding arbour (18) 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 invention concerns a timepiece including a dial (12) fitted with an aperture (16) behind which is mounted a moon phase disc (18) driven in rotation by a moon phase train (24). According to the invention said disc (18) is mounted so as to move in rotation about a fixed sun pinion (36). Moreover, two planetary wheels (44a, 44b), secured in rotation to representations of the moon (19a, 19b), are mounted so as to move in rotation on the disc (18), at least indirectly meshed with the sun pinion (36), so as to form a planetary train with the sun pinion (36).
摘要:
Multi-sector mechanism (1) for displaying a physical quantity on a timepiece (100), on several partial displays (2), each representing the change in said physical quantity over a given partial range (3), the total range of variation in said quantity being covered by the set of said partial ranges (3), each partial display (2) including an indicator (4) that moves relative to a scale (5) representing the partial range (3) specific thereto.Each partial display (2) includes a continuous mechanism (11) for moving the moving indicator (4) thereof opposite a scale representing said total range, and includes eclipsing means arranged for only allowing said moving indicator (4) to be seen opposite said scale (5) representing the partial range (3) specific thereto, and for reducing or obscuring visibility of said moving indicator (4) opposite the scales representing any other partial ranges, and said continuous mechanisms (11) of said partial displays (2) are all synchronous with each other.

The invention comprises a chronograph watch including a chronograph mechanism. The chronograph mechanism includes a chronograph train (50), and a counter mechanism (64) kinematically connected to the train (50). The counter mechanism (64) further includes first and second wheel sets (78, 82) respectively provided with first and second display members (36, 38), wherein the first wheel set (78) is angularly positioned using positioning members (86) so as to rotate in steps, and the second wheel set (82) is angularly positioned by the first wheel set (78).

The oscillating weight (2) 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 (2) is carried by a shock absorber (1) that takes the form of a plate (4), one end of which is secured to the weight and the other end of which is secured to a tube (5) arranged to rotate about an arbour (6) forming the axis of rotation of the weight.

The dial (4) of the watch is fitted with an indicator (10), preferably with a hand (11), which displays the function fulfilled by a control crown (8), 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 (15) secured to the crown, via a transmission mechanism (30) including a slide block (35) that is mobile parallel to an axis of rotation (14) of the crown. The hand is secured to a pinion (32) meshed with a rack (34) arranged on a slide block. The slide block includes a flexible part (38) between a back part that slides in a groove (36), and a front arm (39) provided with a lateral finger (40) engaged in an annular groove of the sleeve. This transmission is compact and facilitates assembly and removal.
