1875 Joseph Bulova, a 23-year-old Czech immigrant, opens a small jewelry shop on Maiden Lane in New York City.
1912 Bulova sets up its first plant dedicated to the production of watch components and their assembly into jeweled movements in Bienne, Switzerland.
1952 Bulova begins developing Accutron, the first breakthrough in timekeeping technology in over 300 years. Accutron, the first fully electronic watch, promises to keep time to within 2 seconds a day.
1961 Accutron, the first watch to keep time through electronics, is introduced. It is the most spectacular breakthrough in timekeeping since the invention of the wrist watch. This revolutionary timekeeping concept of a watch without springs or escapement is operated by an electronically activated tuning fork. The Accutron watch goes on to become a presidential gift to world leaders and other dignitaries. President Johnson declares it the White House's official "Gift of State."
1962 The Accutron Tuning-fork watch becomes the first wristwatch certified for use by railroad personnel. 1962 is also the year that Bulova introduces its Caravelle line of jeweled watches. Designed to retail at $10.95 to $29.95, Caravelle competes with non-jeweled watches in the same price range.
