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: A movement includes a tourbillion block, a tourbillion unit, and a zero reset mechanism. The tourbillion unit includes a carriage, a balance wheel, and an escape wheel. The balance wheel and the escape wheel are rotationally arranged on the carriage. The carriage is rotationally supported on the tourbillion block. The zero reset mechanism includes a first wheel in engagement with the escape wheel. The movement is switchable between a driving mode and a reset mode. When in the driving mode, the zero reset mechanism is rotationally locked to the tourbillion block. When in the reset mode, the zero reset mechanism is rotatable relative to the tourbillion block.

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.
