The first accurate watch was the Bulova Accutron. It used a tuning for that resonated at a specific frequency. It started production around 1960. Seiko unveiled the first quartz watch in 1969. A quartz watch is just what the name implies. It uses quartz crystals for timing. The technical term is reverse piezoelectricity. when an electrical charge is applied to quartz crystals, they oscillate at 32,768 times a second. A microchip detects these oscillations and after 32,768 oscillations causes the hands to move one second forward.
This concludes our lesson on watches today.
