Abstract: A horological mechanism (1000) with a first train (100) and a first output wheel set (101), a second train (200) and a second output wheel set (102), for alternately displaying on a display (800, 8, 28) a first and a second indication respectively specific to the first train and second train, by a switching and coupling mechanism (500), including two input wheel sets (1; 2) connected to the output wheel sets, which includes a sliding wheel set (5) capable of moving under constant strain between the two input wheel sets, and cooperating alternately and exclusively with either one, selected under the action of a command from a user, to establish a driving connection between the input wheel set engaged with the sliding wheel set at the given moment in time, and a display (800, 8, 28) to produce a switchable display.

Abstract: A horological mechanism with a first mechanism (100) and a first output wheel set (101), a second mechanism and a second output wheel set (102), for displaying a first or a second indication specific to the first mechanism (100) or second mechanism (200), by a switching and coupling mechanism (500), including, on a coupling arbor (937, 938), two input wheel sets (1; 2) connected to the output wheel sets (101; 102), a sliding wheel set moving under constant strain between these input wheel sets (1; 2), and cooperating alternately and exclusively, by clicking in a single angular position per revolution, with either one, selected under the action of a command from a user on a controller, to establish a driving connection between the input wheel set engaged with the sliding wheel set at the given moment in time, and a display means.

Abstract: A display mechanism (10) for a timepiece (1000), with a leap year display integrated in a month display, comprising a control mechanism (3) that drives, once per month, about an axis (D), a month display wheel set (2) arranged underneath a dial (1), having a month window (1C) in a quadrant allowing the display of only one quarter of the month display wheel set (2), which completes one revolution in four years, and bears, on an angular sector of 90°, at least one characteristic leap year marking, and either carries indices, each arranged to indicate one month on a static month scale of the dial (1), or equidistant month markings, wherein one of the month markings is pointed to by a fixed mark of the dial (1).

Abstract: An end link for securing a watch strap on a watch case including a connecting piece of a wristband, the watch case having a pin. The case has a longitudinal slot delimited by two support surfaces parallel to a main plane. The connecting piece has a lateral face which includes a guiding groove arranged to cooperate in a complementary manner with the pin, and the connecting piece has a lock with a slide catch arranged to cooperate with the slot in a locking position, towards which the slide catch is moved by elastic return belonging to the lock. There is unlocking portion arranged to be operated directly by a user to move the slide catch away from said slot of the case. The guiding groove is curved so that the slide catch is firmly maintained against one of the two surfaces in the locking position.

Abstract: An adjustable lever (100) of a tourbillon mechanism for stopping at least one tourbillon unit (200). The adjustable lever (100) includes at least one first member (110) configured to be actuated, at least one second member (120) configured to actuate at least one brake element (240) and at least one adjustment member (130) configured to adjust a position of the at least one second member (120) via a method of adjustment.

Abstract: A striking mechanism is provided, including a hammer including an elastic stop that is needle-shaped, and an eccentric supporting the stop in a rest position of the hammer.

Abstract: A clockwork movement with a tourbillon unit, including a base plate, a mobile cage mounted rotatably on the base plate and connected to a second pinion, a balance mounted on the mobile cage and an escape wheel mounted on the mobile cage and being in operative connection with the balance, a balance wheel stop mechanism being capable to be brought into engagement with the balance, wherein it further includes a setting mechanism controlled by an external actuating device for any angular orientation of the mobile cage.

Abstract: A barrel for a timepiece. The barrel has a device for limiting the number of running rotations of the barrel, wherein this device still allows any number of winding rotations of the barrel.

Abstract: A bracelet includes a plurality of links assembled in an articulated manner using pins. Each pin passes through interlocking parts of links in which a cylindrical passage is arranged where a pin can slide relatively freely. In order to ensure the position of the pin once the links have been assembled, a locking element is arranged in a cavity made in one of the links so as to partially intersect the passage in which the pin is arranged. This pin includes a groove, which is penetrated by an external part of the locking element when the element is in the closed position. Pressing on the locking element, then rotating it by an angle of 90°, releases the external part of the pin groove so that the pin is then released.
