| A timepiece movement includes a magnetic escapement formed of a magnetic escape wheel with an annular magnetized structure and a pallet fork whose shaft is formed by a ferromagnetic material.

A magnetic compensation pin is incorporated in the timepiece movement, this magnetic compensation pin being arranged such that the second magnetic disturbance torque that it exerts on the escape wheel exhibits an angular phase shift relative to the first magnetic disturbance torque generated by the pallet shaft, so as to compensate largely for this first magnetic disturbance torque. | ||||||
