The timepiece movement includes a magnetic polarizing device for the balance spring for maintaining a predefined state of polarization in the balance spring and including a permanent magnetizing device which forms a magnetic field in the plane of the balance spring so as to totally or almost totally magnetically saturate the balance spring in the absence of an external magnetic field.
