Thanks everyone for the prompt and numerous responses. It was really an
academic question. He was curious what the division was for 4.194304 MHz
to get it to 1pps.

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.

2^22 = 4,194,304
So divide by two, 22 times in a row to get to 1 Hz.

A friend has acquired a Chelsea Clock Company Chronoquartz which was
probably made in the 70's. He has measured the oscillator frequency at
approximately 4.194304 MHz. He wanted to know what arrangement of
dividers they used to run the 4 pole stepper motor to step seconds.
Anybody know?
Thanks,
