Bulova is famous for a number of horological innovations, perhaps most notably the Accutron watch which used resonating tuning forks as a means of regulating the time keeping function. The “Accutron” tuning fork watches use a 360 hertz tuning fork to drive a mechanical gear train. The inventor, Max Hetzel, was born in Basel, Switzerland, and joined the Bulova Watch Company of Bienne, Switzerland, in 1948. This outstanding engineer was the first one to use an electronic device, a transistor, in a wrist watch. Thus, Max Hetzel developed the first watch in the world that truly deserved the qualification “electronic”- the world-famous “Bulova Accutron.” 

They also were subjects of the other famous space era rivalry with Omega Watches for being the first watch on the moon. Ultimately, the Omega Speedmaster Professional chronograph wristwatch (known as the “Moon watch”) was designated by NASA for use by the astronauts in all manned space missions, becoming the first watch on the moon on the wrist of Edwin ‘Buzz’ Aldrin. However, all instrument panel clocks and time-keeping mechanisms in the spacecraft on those missions were Bulova Accutrons with tuning fork movements.
