A horological movement ( 1 ) including a running train ( 100 ) driven by a first power source ( 150 ) and regulated by a regulating member ( 120 ); a chronograph mechanism ( 10 ) including a chronograph train ( 20 ) driven by a second power source ( 35 ) including a chronograph counter ( 23 ) having a counter wheel ( 231 ); a chronograph start/stop control device ( 30 ) configured to couple on demand the chronograph train ( 20 ) to the regulating member ( 120 ); a reset mechanism ( 40 ) for resetting said chronograph counter ( 23 ), including a reset control ( 60 ) movable between a neutral rest position and a reset position; the chronograph mechanism ( 10 ) including a lever ( 70 ) configured to be controlled by the chronograph start/stop control device ( 30 ) between a first stable position wherein the lever ( 70 ) blocks the rotation of the counter wheel ( 231 ) and a second stable position, wherein the counter wheel ( 231 ) is free to rotate.

A chronograph mechanism including a zero-reset mechanism for resetting a chronograph counter to zero, including a zero-reset member and a hammer shaped to cooperate with the zero-reset member. The zero-reset member is a snail cam including a cam track extending in a spiral. The hammer can be displaced by the zero-reset control between a rest position in which the hammer is not in contact with the cam path and a zero-reset position in which the hammer is in contact with the cam path and holds the zero-reset member in the reference position, the hammer generating a driving torque on the zero-reset member between the rest position and the zero-reset position.

A mechanism for displaying the periods of an annual cycle ( 100 ) for a timepiece ( 200 ) capable of being driven by being dragged by a running train ( 10 ) of a horological movement ( 1 ), characterised in that the mechanism for displaying the periods of an annual cycle ( 100 ) includes: an indicator indicating the periods of an annual cycle ( 110 ); an annual cycle train ( 120 ) capable of being driven by said running train ( 10 ) of the horological movement ( 1 ), and of rotating the indicator of the periods of an annual cycle ( 110 ); the mechanism for displaying the periods of an annual cycle ( 100 ) being characterised in that the annual cycle train ( 120 ) forms a gear train configured to have a ratio of 1:365.2 or a ratio that is a multiple of 1:365.2 between the running train ( 10 ) and the indicator of the periods of an annual cycle ( 110 ).

A friction system ( 100 ) for a horology movement including: an arbor ( 1 ) with a longitudinal axis (L) including: a first fixed element ( 2 ) mounted so as to rotate integrally with the arbor ( 1 ) and having a first support surface (40); a second fixed element ( 7 ) mounted so as to rotate integrally with the arbor ( 1 ); a toothed organ ( 3 ) mounted so as to rotate freely on the arbor ( 1 ) between the first fixed element ( 2 ) and the second fixed element ( 7 ). The toothed organ ( 3 ) is integral with a socket coupling ( 4 ) having a second support surface ( 42 ), and the second fixed element ( 7 ) includes a body ( 72 ) configured to rotate integrally with the arbor ( 1 ) and resilient brackets ( 71 ) protruding relative to the body ( 72 ) and extending towards the toothed organ, the resilient brackets ( 71 ) being resiliently pressed against the second support surface ( 42 ) of the socket coupling.

A three-dimensional karussel for a horological movement including a drive device provided with a barrel and a gear train, the three-dimensional karussel including an inertial mass, an elastic return device for the inertial mass and an escapement mechanism, wherein the horological movement includes an inner carriage and an outer carriage, the inner carriage carrying the inertial mass, the elastic return device for the inertial mass and the escapement mechanism, the inner carriage being capable of moving in rotation about a first axis of rotation, the outer carriage being capable of moving in rotation about a second axis of rotation, the inner carriage being housed inside the outer carriage, the drive device being configured to actuate the rotational motion of the outer carriage in parallel with the rotational motion of the inner carriage.
