Quartz crystals vibrate at precise frequencies when electrified

Passing electric current through quartz produces 32,768 precise oscillations per second

Quartz watch timekeeping relies on inverse piezoelectricity, where applying an electric voltage causes a quartz crystal to flex mechanically. Synthetic quartz crystals are cut into tiny tuning forks shaped to vibrate at exactly 32,768 Hertz when driven by a battery circuit. Electronic counters count these oscillations to maintain accurate time.

Quartz crystals vibrate at precise frequencies when electrified: the short answers

Where does this come from, and can I check it?
Passing electric current through quartz produces 32,768 precise oscillations per second. The figure is taken from NIST, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.
Is this really a science fact?
Yes. It sits on the Science shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.
What else can I read about it?
The links under the fact point to a quiz, game, puzzle or calculator on the same subject, and the shelf below shows related facts. The wording here is original, and quoted phrases are marked as quotations.
