Watch comprising a movement arranged to drive a timepiece calendar mechanism, which includes drive means that drive, at each change in month, complementary drive means arranged to drive a month cam whose periphery cooperates with a month feeler arm comprised in the calendar mechanism, where this month cam covers an angular sector of less than 360&#xb0;, and the calendar mechanism includes elastic return means arranged to instantaneously return the month cam in a backward movement, in cooperation with the month feeler, to the position of the first month of the year upon completion of the last day of the preceding year.

Timepiece calendar mechanism

A perpetual calendar for a watch including a movement controlling the daily release, at the moment that the date changes, of a mechanism actuating a perpetual lever of this perpetual calendar is disclosed. The perpetual calendar includes a calendar mechanism, a daily countdown mechanism including a month-end adjustment mechanism, and a differential mechanism. The calendar mechanism is arranged to determine the duration of the current month and is updated at each current month change by the daily countdown mechanism. The differential mechanism is arranged to control, each day at the moment that the date changes, the motion of an additional adjustment cam comprised in the month-end adjustment mechanism, based on the current day of the month taken from the daily countdown mechanism, and also based on the current month duration taken from the calendar mechanism.

The winding device includes a solar pinion mounted for free rotation in a coaxial manner about a central arbor on a winding wheel. The device also includes toothed planetary wheels for meshing with a toothing of the solar pinion. The planetary wheels are mounted for free rotation with play about a respective offset arbor fixed to the winding wheel. The device also includes one or two hooks of a frame fixedly mounted on the winding wheel. In a first direction of rotation of the solar pinion, a planetary wheel is in a locking position in contact with a hook in order to drive the winding wheel. In a second direction of rotation opposite to the first direction of rotation, the planetary wheel is uncoupled so that the rotation of the solar pinion does not drive the winding wheel.

Winding device with unidirectional drive arrangement

Mechanism for displaying the day and phase of at least a first celestial body, comprising a gear train for a constant frequency gear drive on an output of a timepiece movement. This mechanism includes a means for the three-dimensional display of the day and phase of said first celestial body represented by a first mobile component, which is driven by the gear train, which includes a phase train and a day train, each in mesh on an output of this same movement. This phase train and/or this day train include at least one uncoupling means between the input and its output thereof.

The calendar mechanism includes a 31 wheel set () for controlling a date indicator, a date drive means for driving the 31 wheel set, a 12 wheel set () for controlling a month indicator, and a monthly drive means for driving the 12 wheel set at the end of each month. The monthly drive means is activated by the 31 wheel set during the change from the end of one month to the first day of the next month. The calendar mechanism further includes a manually activated month corrector device arranged to advance the 31 wheel set in one stroke to an angular position corresponding to the indication of the first day of the next month, so that the monthly drive means, activated by the change from one month to the next, increments the 12 wheel set by one step.

The timepiece movement has an instantaneous actuator controlled by the movement and arranged to actuate a mechanism of the movement by pushing away one element () of the mechanism against a return force. The actuator includes a trailing wheel () driven by the movement, an eccentric () free to rotate coaxially to the trailing wheel and arranged to abut against and therefore be driven by the trailing wheel, a small wheel () returned by a spring against the periphery of the eccentric, a pivoting wheel set having a projecting portion () free to rotate coaxially to the trailing wheel and arranged to abut against and therefore be driven by the eccentric, the projecting portion () of the pivoting wheel set being arranged to push the element () of the mechanism away in passing against a return force.

Timepiece movement including an instantaneous actuator controlled by the movement

A timepiece includes a movement, a main striking mechanism, a secondary strike release mechanism, and a mode selecting mechanism. The main striking mechanism is controlled by a main strike control mechanism, arranged to release strikes, at times programmed by the movement, or on demand, and a sequence of each strike is determined by information gathered by feeler spindles on snails or time references driven by the movement. A coupling mechanism of the secondary strike release mechanism actuates a control rod linkage of an isolating mechanism arranged to isolate various different release mechanisms for different strikes using the main striking mechanism to play strikes. The isolating mechanism includes at least a first isolator which, in a first winding position, takes a stop position preventing the spindles from gathering information from the snails, and, in a second let down position, allows the spindles to pass to come into contact with the snails.

A timepiece including a movement, a mechanism controlling the power reserve of a drive means with an arbor whose angular position indicates said available torque, a striking mechanism controlled by a striking mechanism control mechanism, and a locking lever arranged to lock said movement.

The downstream stage includes a second hour ratchet which pivots about the axis and whose toothing is inclined in the same direction as that of the first hour ratchet.
