I went looking for the clock and found nothing. But like the rest discovered the divider ratio to 1Hz. But does the conversation stop at that point? Since Bill said the motor was 4 pole wouldn't there be 1 more divider to .5 Hz with the Q and /Q essentially across the coil. Add protection diodes and such. It looks like the Omega timepieces were quite nice. regards Paul WB8TSL
