Accuracy Through Electronics
Making a quantum leap, Accutron’s breakthrough advance in timekeeping—the first in 300 years—substituted the traditional main spring and balance wheels with electronic transistor circuitry, making it the world’s first fully electronic watch, thanks to Max Hetzel, the Switzerland-based electronics engineering genius who saw things differently.
The secret of Accutron’s precision was an innovative tuning fork that activated electronically and oscillated at a never-before 360 times a second. It didn’t tick—it hummed as it vibrated to guarantee accuracy to within one minute a month. Dazzling consumers with record sales of over 5 million watches, it quickly became an American success story, with a hum that was heard ‘round the world.
