The movement includes at least one mobile arranged pivoting coaxially with the pivot axis A and including an outer peripheral toothing, the mobile being housed in the cavity and arranged to carry the indicator member. The mobile includes a felloe including the outer peripheral toothing and defining an inner opening, the felloe carrying an arm passing radially through the inner opening in order to be mounted pivoting on the pivot axis A, the indicator member being represented on the arm. Also disclosed is a timepiece including such a mechanical movement.

Abstract: Disclosed is a timepiece mechanism which has a mobile including a tooth of a first type and a tooth of a second type, and a pawl that is intended to move the mobile by at least one step on each actuation and has a travel that is liable to move the mobile by two steps on each actuation. This timepiece mechanism has a correction mobile designed to define different paths of the pawl, depending on the state thereof, the pawl and the correction mobile being designed such that, on each actuation of the pawl: the pawl moves the mobile by one step; and the pawl moves the mobile by an additional step only when the correction mobile is in a predefined state and the tooth of the second type is situated along the travel of the pawl.

Abstract: An escapement is disclosed which includes pallets, a roller and a pin fastened to the roller, intended to cooperate with one another. The pallets have no guard pin and include a pallet fork intended to cooperate with the pin and the roller and including first and second horns delimiting an entry of the pallet fork. The roller has an anti-overbanking wall in which a notch is formed, in a region adjacent to the pin. The pallets, the roller and the pin are conformed and dimensioned in such a manner that, in the service position, the anti-overbanking wall is able to define an abutment for the first and second horns, and each of the horns is able to penetrate to the interior of the notch exclusively when the pin is at least partly situated in the entry of the pallet fork.

Abstract: Device for displaying phases of the moon with a fist display member (80) bearing a plurality of first images (81-86) at least partially representing the moon, a display zone, driving means (22, 23 ,25, 40. 41, 43, 63, 71, 72, 61, 62) arranged to displace, by successive jumps, the first display member (80) relative to the display zone, to display a succession of representations of the moon. An original feature of the invention is that the periods of display of the first images are not all equal.

Abstract: Disclosed is a timepiece including a display mechanism arranged to control the movements of a display organ with respect to an indication scale including different indications having at least two different widths and being separated from one another by corresponding separation spaces, the timepiece being characterized by the fact that the separation spaces all have substantially one and the same width.

Abstract: A mechanism for adjusting an average speed in a timepiece movement comprises an escapement wheel and a mechanical oscillator, in which a plurality of blades, which are resiliently flexible in an oscillation plane, support and return a balance in such a way that this balance oscillates at an angle in the oscillation plane. A pallet fork comprises two rigid pallets which are rigidly connected to the balance and are arranged to co-operate alternately with a toothing of the escapement wheel when the balance oscillates at an angle.

Abstract: In an annual or perpetual calendar mechanism, a day-of-the-month wheel includes a notch. At each actuation of a lever, a first pawl finger effects an actuation of one step, on one of the teeth of the day-of-the-month wheel. Upon actuation of the lever at the end of a month of fewer than 31 days, a second pawl finger effects, in the notch, an actuation of the day-of-the-month wheel by a whole number of steps. The notch is positioned between two consecutive teeth among the teeth of the day-of-the-month wheel. The day-of-the-month wheel has a peripheral edge which forms the profiles of its teeth as well as the notch.

Abstract: In an annual or perpetual calendar mechanism, a lever bears a maneuvering device of a day-of-the-month wheel. A month wheel defines course beginning stops, each associated with a month and operational for controlling a course beginning position of the lever when the month wheel is in the angular position associated with this month. These course beginning stops are bottoms of slots alternating with the teeth of the month wheel. The month wheel has a peripheral edge which forms the profile of its teeth as well as the course beginning stops.

Abstract: A timepiece comprises a chiming device including at least one pivoting toothed sector called rack (1) intended to cooperate with at least one first part (2), driving a second part (3) secured to a pin (32) cooperating with an eccentric (41) for actuating at least one hammer (4) characterized in that the hammer (4) chimes a gong (5) extending substantially in a plane A by being displaced along a plane B which intercepts the plane A of the gong (5).

Abstract: A coupling device for timepieces that includes an entry wheel, a coupling wheel, and a first exit wheel. The coupling wheel is disposed substantially coplanar to the plane of rotation of the entry wheel and of the first exit wheel and is adapted to tilt relative to the plane of rotation to occupy a first coupling position in which the coupling wheel meshes with the first exit wheel and a second coupling position in which the coupling wheel is decoupled from the first exit wheel. The device also includes a movable element to control the change of position between the first and the second position of the coupling wheel. The coupling wheel defines an axis of rotation that can be inclined relative to the normal to the plane of rotation of the entry wheel and of the first exit wheel by being mounted pivotably at each of the ends thereof.

A first and a second return device are configured to return the first sweep-hand mobile to a first predetermined angular position relative to the intermediate chronograph mobile, in the absence of angular immobilization of the first sweep-hand mobile by a first brake, and the second sweep-hand mobile to a second predetermined angular position relative to the intermediate chronograph mobile, in the absence of angular immobilization of the second sweep-hand mobile by a second brake. A control system includes a coordination device arranged to maintain the first and second brakes alternately in two opposite configurations, in each of which one of the first and second brakes is in an inactive state and the other is in an active state.
