It further comprises a lever (8) provided with a second impulse pallet (11) and with first and second locking pallets (12, 13). The wheel assembly (1) comprises an escape wheel with teeth (6) that mesh directly with the teeth (20) of the last wheel of a gear train (2), the teeth (6) of the wheel (1) engaging with the impulse and locking pallets.

Abstract: The bracelet clasp with an unfolding buckle includes a lever (2) pivotably mounted on a cap (1) by means of a first hinge (3a), said lever controlling a bolt (4) which is in turn mounted on said cap (1) by means of a second hinge (3b) distinct from the first. The bolt (4) is arranged to cooperate with a hook (22) fitted to the first arm (8) of the clasp. Elastic means (5) are arranged for keeping the lever (2) in a non-raised position and the bolt (4) engaged with the hook (22) when the lever is not manually activated.

Abstract: A corrector (1) for a function indicator (20) for a movement (100) including: a first control mechanism (30) for a first function, in a let down (31) or wound (32) position, a second control mechanism (40) for a second function, in a let down position (41) or release control position (42) followed by a return to the preceding position, and a display indicator (20) for a third function. First mobile part (50) driven by the first control mechanism (30) occupies a letting down (51)/winding (52) position, when the mechanism occupies the let down (31)/wound (32) position. Second mobile part (60) actuating the indicator (20) is driven by the second control mechanism (40) changing into the control position (42) when the first mobile part (50) is in a winding position (52) and cooperates with this latter in the letting down position (51), under the action of return mechanism (70).

Abstract: The invention relates to an inlaid ceramic decoration (10) including a ceramic body (11) that has at least one recess (12) forming the pattern for a decoration (13). According to the invention, said at least one recess is entirely filled by first and second electrically conductive layers (14, 15) of approximately 50 nm and a metallic galvanic plating (16) so as to form a ceramic element (10) inlaid with at least one metallic decoration (13) with improved visual rendering. The invention also relates to the method of manufacturing the inlaid ceramic element. The invention concerns the field of decorated ceramic parts.

Abstract: Navigation aid instrument for an aircraft pilot including: a first display device (R3) extending horizontally, wherein the centre of the display device embodies the longitudinal axis (X) of the aircraft, a mobile marker can move on either side of the centre of the first display device (R3) indicating the aircraft flight direction relative to the ground, and the mobile marker is further away from the centre of the display device (R3) the further the aircraft drifts from the rectilinear flight path, and/or two left (R2) and right (R1) display devices that extend vertically at a distance from each other and have the function of indicating the angle of inclination of the aircraft wings relative to the horizontal respectively on the left side or right side of the aircraft, wherein a mobile marker can move either along the left display device (R2), or along the right display device (R1) to indicate to the pilot which way his aeroplane is inclined and the value of the inclination is higher the further the mobile

Abstract: Timepiece device for simultaneously resetting to zero two time counters, particularly for a chronograph mechanism, each of the two time counters pivoting about an arbour secured to a cam (6b, 8b), the simultaneous zero reset device (1) including a lever (4) with two hammers (6, 8), which are applied against the respective cams (6b, 8b) when the two time counters are reset to zero, at least one pin (10, 12) used to guide the lever (4) with two hammers (6, 8) being secured to said lever (4) and moving in a shaped aperture (24, 26) made in a bridge (28), characterized in that a ring (16a, 16b, 16c) is mounted to rotate freely about the pin (10, 12) and is inserted between said pin (10, 12) and the shaped aperture (24, 26) in which said pin moves.

Abstract: The invention relates to a device for correcting a time indication given by a display mechanism for a timepiece of the type comprising a first display member, comprising: a winding stem arranged to occupy at least one time indication correction position A, a pinion coupled in rotation to the winding stem, a correction motion transfer connected kinematically to the pinion when the stem is occupying the correction position A, and a correction wheel assembly engaging with the display member and operated by the correction motion transfer. According to the invention, the correction motion transfer is formed by a ring having an internal circumference and an external circumference, at least one of which is provided with teeth meshing at least indirectly with said correction wheel assembly.

Abstract: The escapement comprises an escape wheel assembly (1), a balance roller (3) carrying an impulse pin (4) and a first impulse pallet (5). It further comprises a lever (8) provided with a second impulse pallet (11) and with first and second locking pallets (12, 13). The wheel assembly (1) comprises an escape wheel with teeth (6) that mesh directly with the teeth (20) of the last wheel of a gear train (2), the teeth (6) of the wheel (1) engaging with the impulse and locking pallets.

Abstract: Time zone timepiece including an hour hand (6) capable of being moved forward or backward in one hour steps by means of a manually actuated time setting stem (28) without affecting the minute display, said hand (6) being fitted onto an hour pipe (4) about which an hour hand (2) is adjusted to pivot freely, driven by a motion work (10), an additional wheel (12) secured to the pipe (4) driving an additional device, the hour wheel (2) being coupled to the additional wheel (12) by a limited torque mechanism (16), the timepiece being characterised in that, outside the periods in which the time zone time is being corrected, the hour wheel (2) and the additional wheel (12) are further rigidly coupled by a second coupling mechanism.
