Watch Fact of the Day: The Accutron's Tuning Fork Humming Sound of Space! In 1960, Bulova's Accutron made traditional watchmakers sweat by ditching the tick for a hum, thanks to its tuning fork vibrating at a whopping 360 times per second. This made it as accurate as a stopwatch on a caffeine high, promising one minute’s delay per month. Unlike other watches that just counted seconds, the Accutron serenaded its wearer with an F-sharp melody. It didn't just stay on wrists, though; it buzzed into NASA's heart, timing everything from cockpit instruments to space missions. So, if you're looking for the ultimate party trick, just bring an Accutron close to your ear and enjoy the high-pitched symphony of timekeeping history!
