Abstract:
Timepiece movement for a mechanical watch, comprising, arranged on a main plate, a resonator mechanism with two degrees of freedom, and a maintaining mechanism subjected to the torque of driving means comprised in the movement, wherein this maintaining mechanism is a continuous maintaining mechanism, and includes a crank movable about a crank rotational axis, and which includes, on the crank rotational axis, an axial element subjected to the torque of driving means, and, off-centre relative to the crank rotational axis, a crankpin which is arranged to travel on a track of a stiff ring comprised in the resonator mechanism, this stiff ring being movable in the two degrees of freedom.
