ABSTRACT:
An analog style electronic watch employing an IC controlled electromagnetic system for driving concentrically mounted second, minute and hour ring indicators. Each ring has a plurality of equidistantly spaced permanent magnetic elements which enable the ring to be incrementally indexed by pulsed electromagnets. No gears or wheels are used. The electromagnets drive mechanism responds to clock pulses from the IC which supplies a core-wound electromagnet having asymmetric north-south poles for developing attractive and repulsive forces with respective to pairs of permanent magnet element on said rings. Asymmetry is achieved by varying the cross-sectional area of the core along the poles. The direction of ring rotation may be reversed by changing the direction of current flow in the winding.
