Since 1960, Bulova's Accutron brand has defined the ultimate in precision timekeeping. As the world's first fully electronic watch, Accutron revolutionized the way the world told time, offering what was then the most accurate timekeeping mechanism ever devised. When Accutron debuted on October 25, 1960 it was the most accurate timing mechanism available and the first personal timekeeping advancement in 300 years. The world's first electronic watch without springs or an escapement, it was operated by an electronically activated tuning fork, instead of ticking, it hummed. Bulova Accutron had an important place in history as an integral part of 46 missions of the US space program. Before the technology was available commercially, NASA requested its use in the development of the United States' greatest single engineering achievement, man's first landing on the moon. In addition to the role Accutron technology played in the missions leading up to the first manned lunar landing, on July 20, 1969, Neil Armstrong and Buzz Aldrin placed an Accutron timer in the Sea of Tranquility to control transmissions of data to earth.
