MECHANICAL TIMEPIECE MOVEMENT WITH A RESONATOR HAVING TWO DEGREES OF FREEDOM WITH A MAINTAINING MECHANISM USING A RUNNER ROLLING ON A TRACK

摘要

Timepiece movement (500) for a mechanical watch (1000), comprising, arranged on a main plate ( 1 ), a resonator mechanism ( 100) with two degrees of freedom, and a maintaining mechanism (200) subjected to the torque of driving means (300) 10 comprised in the movement (500), wherein this maintaining mechanism (200) is a continuous maintaining mechanism, and includes a crank (7) movable about a crank rotational axis (OM), and which includes, on the crank rotational axis (OM), an axial element (71) subjected to the torque of driving means (300), and, off-centre relative to the crank rotational axis (OM), a crankpin (72) which is arranged to travel on a 15 track (82) of a stiff ring (8) comprised in the resonator mechanism ( 100), this stiff ring (8) being movable in the two degrees of freedom.
