Abstract: A system (1) for resetting a chronograph is provided with a chronograph counting geartrain (2), which includes a minute counter having a minute wheel set (4), and a seconds counter, which includes a chronograph wheel set (3). The system includes a hammer held blocked by blocking device (11) and displaceable from an inactive position, where the hammer is blocked by the blocking device, and an active position, when the hammer is unblocked, for resetting the chronograph in contact with the various wheel sets (3, 4); a flexible element (10) connected between a reset controller (12) and the hammer for resetting the chronograph, and configured to store energy during a displacement of the controller and before unblocking the hammer blocked by the blocking device to be able, when the hammer is unblocked, to restore this stored energy and drive the hammer to reset the chronograph.

Abstract: The vertical coupling/uncoupling device includes a switching member and a control member, the latter being arranged to pivot about an axis of rotation to be able to be driven in rotation step-by-step successively into a plurality of distinct angular positions. The control member and the switching member respectively include a first magnetic structure and a second magnetic structure arranged to exhibit a magnet interaction therebetween. These first and second magnetic structures are arranged such that, depending on the angular position of the control member, a first magnetic force or a second magnetic force is produced, these first and second magnetic forces being oriented along said axis of rotation but in opposite directions. The switching member is subjected to an alternate movement between its first and second stable axial positions when the second magnetic structure is driven in rotation step-by-step in said given direction of rotation.

Abstract: Sub-assembly for watches, including an arbor including a magnetized or electrically charged surface pivoting inside a housing, and a pole piece subjecting this surface to a magnetic or electrostatic field about an axis, one pole piece cooperating axially with this surface to absorb a shock and then return the arbor to an operating position, and creating, in proximity to this surface, a magnetic or electrostatic field, which radially attracts the arbor towards a wall of the housing.

Abstract: A magnetic device for centring a shaft on a predetermined axis in a clockwork movement includes at least one first magnetic bearing provided with a magnet to exert an attractive force on a first ferromagnetic end pivot of the shaft. The first magnetic bearing includes a central part made of soft ferromagnetic material mounted between the magnet and the first end pivot of the shaft. The central part is positioned centrally in a washer made of non-magnetic material so as to centre the magnetic field flux generated by the permanent magnet through the central part in order to magnetically attract the first end pivot of the shaft on the predetermined axis. The diameter of the central part can be identical to, or 0 to 20% less than, or 0 to 20% greater than, the diameter of the first end pivot.

Abstract: A mechanical watch movement includes a striking mechanism with a first cannon equipped with a first cannon pinion having at least one snail intended to cooperate with a sensor device of the striking mechanism. The watch also includes a second cannon equipped with a second cannon pinion and carrying the minute hand. The first cannon pinion engages with a going train of the movement and a minute wheel. The minute wheel engages with the first cannon pinion. A motion-work pinion engages with an hour wheel coaxial with the second cannon. The minute wheel is mounted on a lever arranged to pivot about a fixed point. An angular position of the lever may be adjusted by pivoting in such a way as to permit regulation of the position of the minute wheel with respect to the first cannon pinion and to the second cannon pinion.
