QUARTZ CRYSTALS USED IN DIGITAL WATCHES ARE TYPICALLY MADE TO
OSCILLATE AT 32,768 HZ BECAUSE 32,768 = 2^15, A BINARY-FRIENDLY
NUMBER. THAT LETS A SIMPLE CHAIN OF 15 DIGITAL DIVIDE-BY-TWO STAGES
(FLIPFLOPS) REDUCE THE CRYSTAL'S FREQUENCY TO EXACTLY 1 HZ, PRODUCING
ONE PULSE PER SECOND FOR THE TIMEKEEPING LOGIC WITH VERY LITTLE EXTRA
CIRCUITRY.
