The invention discloses movement and a mechanical watch with the movement and belongs to the technical field of watches. The movement comprises a movement clamp plate and a rotatable automatic rotor, the clamp plate is located at the back of the movement, the automatic rotor and the movement clamp plate are on the same layer and eccentrically arranged relative to the center of the movement, and the radius of the automatic rotor exceeds half of the radius of the movement to allow the rotation trajectory of the automatic rotor covers the center of the movement. Compared with movement of the same size, the movement has the advantages that the size of the automatic rotor is larger than the size of a pearl rotor in the prior art, the movement is high in movement ability, a clockwork spring can be driven by power generated by self-weight, and the winding efficiency and reliability of the movement are guaranteed.
