Drawing its power from a unique tuning fork system, the Bulova Accutron was the world"s first electronic replica watch . Inside the casing, a 360 hertz tuning fork sat between two electromagnet coils, which formed a single-transistor oscillator circuit. This drove the fork, which in turn powered the watch"s hands and allowed the device to keep time.
