    Abstract: A DIRECT CURRENT ELECTRIC TIMEPIECE COMPRISING A BALANCE WHEEL ASSEMBLY INCLUDING A SHAFT, A BALANCE WHEEL MOUNTED ON THE SHAFT, AND PERMANENT MAGNET MEANS MOUNTED ON SAID BALANCE WHEEL ECCENTRIC OF SAID SHAFT AND MOVABLE ALONG AN ARCUATE PATH IN OPPOSITE DIRECTIONS FROM A NEUTRAL POSITION LYING ON A PLANE EXTENDING RADIALLY OF THE SHIFT. FIXED ELECTROMAGNETIC COIL MEANS ARE CENTERED ON THE NEUTRAL PLANE OUTWARDLY OF THE SHAFT AND MEANS ARE PROVIDED FOR SELECTIVELY ENERGIZING AND DE-ENERGIZING THE COIL MEANS TO SUCCESSIVELY REPEL THE PERMANENT MAGNET MEANS ON THE BALANCE WHEEL, THEREBY PROVIDING MAGNETIC IMPULSE FORCES FOR OSCILLATING THE BALANCE WHEEL IN OPPOSITE DIRECTIONS FROM THE NEUTRAL POSITION. AN EDDY CURRENT DAMPER IS POSITIONED DIAMETRICALLY OPPOSITE THE COIL MEANS ADJACENT THE PATH TRAVERSED BY THE MAGNET MEANS ON THE BALANCE WHEEL FOR OPPOSING THE MOVEMENT OF THE BALANCE WHEEL AS IT OSCILLATES TO PREVENT OVERBANKING OF THE BALANCE WHEEL WHEN THE BATTERY POWER IS IN THE HIGH VOLTAGE RANGE. THE BALANCE WHEEL ASSEMBLY DRIVINGLY ENGAGES AN ESCAPEMENT LEVER WHICH ROTATES A TOOTHED ESCAPEMENT WHEEL IN SYNCHRONISM WITH THE OSCILLATION OF THE BALANCE WHEEL ASSEMBLY. THE ESCAPEMENT WHEEL IS MOUNTED ON A SHAFT, AND SPRING MEANS IS DISPOSED AT ONE END OF THE SHAFT FOR BIASING THE SHAFT AXIALLY AGAINST A BEARING SUPPORTING THE OPPOSITE END THEREOF TO PROVIDE BRAKING ACTION ON THE SHAFT TO PREVENT OVERTRAVEL OF THE ESCAPEMENT WHEEL.
