Abstract: Method for adjusting the rate of a basic oscillator of a watch arranged to oscillate at a nominal frequency N0, with a master oscillator generating an excitation frequency NE approximately equal to an integer multiple of this nominal frequency N0, the master oscillator subjecting the watch to excitation or a modulated motion during a transition phase after which the basic oscillator is stabilised at the excitation frequency NE, and a state of display correction method with a winder for mechanical or automatic watches, moving a support carrying the watch and comprising a state of display correction oscillator, having a lower variation of rate value than the initial variation of rate value DI of this basic oscillator, and oscillating at a correction frequency NC to impose oscillation or a motion on the watch, during a state of display correction phase whose duration is adjusted to exactly correct a state of display error measured at the initial moment of actuation.

Abstract: A device for attaching an end of a bracelet to an object, including a support plate, a control member, two pins slidably mounted on the same axis, called the sliding axis, wherein the control member is mounted to move in translation on an arbor, called the translation arbor, which is substantially perpendicular to the support plate, and wherein the control member is offset with respect to the sliding axis of the pins and connected to the latter by connecting elements able to transform the translational movement of the control member into a sliding movement of the pins when the control member is actuated.

Abstract: A timepiece movement, a calendar mechanism and device for indicating the sunrise and sunset that takes account of seasonal variations. The simple calendar mechanism includes a display mechanism for displaying the date and a display mechanism for displaying the month. The sunrise and sunset indicating device also includes an annual cam having a profile representative of the tilt of the sun with respect to the equatorial plane and arranged to be driven in rotation via the hour wheel set through a kinematic chain that passes through the month display device and has a transmission ratio of 1:744.

Abstract: A watch includes a pedometer mechanism for estimating a physical activity level. The watch includes at least one moving or pivoting weight arranged to drive a ratchet, an elastic or friction holder for holding the ratchet in position between two movements of the moving or pivoting weight, the ratchet driving a gear train displaying, on a display, a value corresponding, to within a multiplicative factor, to the number of pivoting motions of the ratchet, and/or to the value of the cumulative angular rotation of the ratchet, and the pedometer mechanism includes a limiter only allowing the pivoting of the ratchet from a minimum threshold corresponding to a minimum travel of the weight if the weight is movable or to a minimum angular rotation value of the weight if the weight pivots.
