A method and apparatus for accurately controlling a timekeeping apparatus utilizing a relatively heavy free pendulum or other harmonic structure carrying a permanent magnet, and a powered harmonic structure carrying a ferromagnetic element. The magnet is positioned on its carrier in a manner to effect energy transfer between the pendulums or structures during intermittent periods of magnetic attraction as the two structures oscillate. The free structure governs the speed of oscillation of the powered structure to maintain accurate control over the latter and energy transferred from the powered structure to the free structure maintains continued oscillation of the governing, free structure.
