A setting machine (1000) for making a setting and/or adjustment on an assembly (1) attached to a receptacle (10), including a positioning module (100) to move this receptacle (10) on command from control means (3000) to convey it into a setting and/or adjustment position below an acquisition module (200), which includes measuring and/or testing means for determining the spatial position of the receptacle (10), and including a setting and/or adjustment module (400) for making a setting and/or an adjustment with motorised axes for moving, opening and closing, in a clamp plane perpendicular to a clamp rotation direction (DF, DG), a clamp (600) arranged to drive or deform a mobile component or a component included in such an assembly (1) borne by a receptacle (10), and method for using such a setting machine for setting and/or adjusting at least one horological component.

The timepiece includes a chronograph mechanism with a coupling device including an operating member and a switching member which can be switched alternately between two stable positions coupled state and uncoupled state. This timepiece includes a magnetic system formed of a first bipolar magnet fixed to the switching member, a second bipolar magnet fixed to the support of the switching device in order to continually offer a magnetic interaction with the first bipolar magnet, and at least one highly magnetically permeable element forming the operating member and able to undergo a reciprocating motion between two operating positions. The switching device is arranged so that, when the highly magnetically permeable element is in its first operating position, the two magnets generate between them a force of magnetic repulsion and so that, when the highly magnetically permeable element is in its second operating position, the two magnets generate between them a force of magnetic attraction.

Timepiece movement comprising a mechanism and a spring barrel provided in order to drive the mechanism. The spring barrel comprises a drum and a motor spring in order to exert a driving torque which is variable as a function of the degree of winding-up of the motor spring. The timepiece movement comprises furthermore an equalisation device which is connected kinematically to the spring barrel in order to be able to be driven by it and to be able to exert an auxiliary torque which varies as a function of the degree of winding-up of the motor spring so as to counter variations in the motor torque. The equalisation device comprises a first magnetic element and a second magnetic element which are provided such that, when the equalisation device is driven by the spring barrel, they are displaced one relative to the other by exerting one on the other a magnetic force which varies as a function of the relative position occupied by the first magnetic element and the second magnetic element and which produces the auxiliary torque.

The mechanical timepiece movement with power reserve indication comprises at least one barrel system connected to a winding wheel of a differential gear and an unwinding wheel of the differential gear. An intermediate wheel of the differential gear is connected to a cam wheel set to drive it in rotation via a reducing stage. A rack, which acts on a power reserve indicator, is in contact with the cam wheel set. When the power reserve is at zero, a locking part of the rack comes into contact with a locking member to lock the movement at an unwinding output of the barrel system or in contact with the unwinding wheel of the differential gear.
