AccutronIn 1960, the Accutron 214, the world's first electronic wristwatch by Bulova, was placed on sale in New York City. The original circuit used a germanium PNP transistor circuit with a 360-Hz tuning fork, used for timing accuracy. In 1977 it was replaced by quartz watches. The Accutron has the potential accuracy of better than 2 seconds per day, remarkable in its day of mechanical watches. In 1953, tuning fork watch development began in Switzerland and prototype watches were made in 1955. Its Swiss engineer was Max Hetzel, who moved in 1959 to continue his development of the Bulova Accutron in New York with William Bennett. The CEO of Bulova at the time was Omar Bradley, 5 Star General, US Army, Retired.
