Abstract: Clockwork movement for a wristwatch, comprising a kinematic chain including at least one belt (20, 21) for transmitting the movements and/or couples between at least two pulleys. The pulleys are held on the bottom plate or the bridges by ball bearings (151, 161, 171, 181). The movement is rewound by means of linear oscillating mass (14) charging four barrels (15, 16, 17, 18) through a couple distributor (40). The barrels are non-parallel to one another. The back cover is covered by inclined glasses (110, 120, 130) allowing the barrels, the linear oscillating mass and at least certain pulleys to be seen. The regulating organ (51) is removable.

Abstract: A timepiece part, includes a frame having a power source, a housing including a first pivotal movement system and a second pivotal movement system; an escapement set up on a mounting, a first kinematic linkage including a first wheel borne by a first half-shaft from the first pivotal movement system and a second wheel borne by a first half-shaft from the second pivotal movement system, and a second kinematic linkage including a first wheel borne by the second half-shaft from the first pivotal movement system and a second wheel borne by the first or second half-shaft of the second pivotal movement system. One of the wheels borne by the second pivotal movement system is kinematically linked to the power source, and the other wheel borne by the pivotal movement system is stationary relative to the frame. Both wheels borne by the first system are kinematically linked to a differential.

Abstract: Mechanical watch movement comprising a mechanical chronograph with a regulator organ for regulating the running of the chronograph, characterized in that the regulator organ of the chronograph is placed in an imaginary circle (A) coaxial to the movement and having a radius (r1) smaller than 50% of the maximum outer radius of the movement.

Abstract: A regulating member for a wristwatch movement includes a balance having at least one mobile magnet and a magnetic return member having at least one fixed permanent magnet. The permanent magnet engages with the mobile magnet of the balance, so as to generate a mechanical restoring torque for bringing the balance towards at least one resting position. The regulating member further includes an escapement for transmitting pulses to the balance so as to move the balance away from the resting position, and at least one yoke made of a ferromagnetic material for concentrating a magnetic flux of at least one of the permanent magnets.

Abstract: An arrangement for protecting a watch movement from shocks and vibrations includes shock absorbers for mounting the watch movement within the case. The shock absorber includes a plurality of independent portions for absorbing the energy from shocks and vibrations in different portions of the frequency spectrum. The rigidity of the shocks absorbers can be adjusted from outside the watch. The watch case is made up of a network of interconnected tubes and watertightening plates without mechanical functions connected to the tubes.

Abstract: A device comprises a basic clock movement MB whose time indicators are driven by a first barrel connected to a first wheelwork and a first regulator organ, and an autonomous chronograph module MCA whose indicators are driven by a second barrel independent from the first, connected to a second wheelwork and a second regulator organ. The chronograph module is exclusively composed of mechanical elements. The frequency of oscillation supplied by its regulator is equal N times the frequency of oscillation supplied by the regulator of the base movement, with the coefficient N being definable according to a specific application of the chronograph, so that any chronograph module thus previously defined can work with the same base movement. The chronograph regulator remains constantly engaged with the corresponding wheelwork. The chronograph module allows a time interval to be read with a minimum precision of a hundredth of second.
