Estate of Flory Van Donck The Bulova Accutron represents a fascinating page in horological history, marking a technological rיvolution in the 1960s. Launched in 1960, the Accutron was the first יlectronic watch for the general public, using a vibrating א 360 Hz tuning fork rather than a traditional balance wheel. This innovation made it possible to achieve remarkable precision for the time: a drift of just one minute per month, ten times more precise than a conventional mechanical watch. The development of this technology was closely linked to the American space programme. NASA adopted Accutron movements to equip its on-board instruments, and these mechanisms accompanied the Apollo missions to the Moon. This association with space conquךte contributed greatly to the brand's prestige. The Accutron was also distinguished by its futuristic design and its characteristic buzzing sound, replacing the traditional mechanical ticking. The dials, often dיpped in numerals, and the bold shapes reflected the aesthetics of the י space age. Although the adטvent of quartz in the 1970s gradually supplantedי this technology, the Accutron remains an important milestone of horlogטre innovation, tיmoignant of a יperiod when the industry was exploring new technological avenues.
