People sometimes refer to the Accutron as the worlds first electric watch. This isn't quite true but as it was the first to use a bipolar transistor it certainly deserves the former accolade. The first Accutron was manufactured in 1960 and was the watch chosen by some of the 'Original Seven' NASA astronauts  to accompany man on his first journeys into space. the watch uses a tuning fork as its prime moving element. It is a well understood physical principle that the faster your initial reference the more accurate your time keeping will be. The most accurate clocks nowadays use the vibrations of a caesium atom as their reference. In the 1950s the best mechanical watches could rely on a prime moving element with a frequency of around 2 Hz (That is two 'beats' per second). Max He
