Abstract: A magnetic escapement including a rotor driven by an external force, and escape wheel made of a magnetic material and having along its periphery radially extending magnetic teeth, said escape wheel being coupled through a coil spring to the rotor, and an oscillator having a magnetic pole piece secured at the end of one of its tines and coupled magnetically to the escape wheel teeth. The oscillator is preferably formed in a W-shape and supported at a point near its center of gravity for extension parallel to the plane of the escape wheel, and its pole piece being magnetically coupled to that tooth of the escape wheel which is farthest from the supporting point. A driving circuit of a constant output for the rotor is provided, which includes a compensating transistor and a temperature compensating element for eliminating load and temperature variations.
