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 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.
