Rare 1967 Bulova Accutron 10K Gold Men's Back Set Quadrant Dial Watch - Original Bracelet


The Bulova Accutron was the world's first electronic watch. 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 cesium 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 Hetzel an engineer employed by the Bulova Watch Company of Bienne Switzerland designed an electrically excited tuning fork movement with a a frequency of 360 Hz. Bulova claimed an accuracy of 2sec per day or 1 min per month. This was the only movement  capable of the accuracy demanded by spaceflight. Accutrons were used as time references in many satellites and also to control some of the Apollo moon experiments.The Tuning Fork Movement is absolutely unique in operation emitting a distinctive hum and featuring a sweeping seconds hand.
