These vibrations then move the index wheel, which is 2.4mm in diameter and has 320 teeth. The coils surround the magnets on the edges of the tuning fork, causing it to vibrate under the influence of the induced magnetic field. Each of the coils contains around 80 meters of copper wire as tiny as one-third of human hair. In a nutshell, the battery powers the transistors and the current goes through two driving coils. Now, what's tuning fork technology, how does the tuning fork watch work, and what are its advantages? Tuning fork technology operation and advantages Max Hetzel, the lead manager behind a team that designed, engineered, and produced Accutron, ( image credit: ) The idea that was more than a century old was built upon by Bulova engineers, led by Max Hetzel, resulting in the premier use of this technology in a wristwatch. The revolutionary approach to making it happen was the use of the tuning fork technology in a watch mechanism. The Accutron took the timekeeping world by storm. The first fully electronic watch, the Accutron, was the most significant watchmaking innovation in the last three centuries. Now, what's so special about Accutron that it makes it Bulova's flagship model? Why NASA chose to use it onboard the rockets and space modules for 46 space missions and which Accutron models have been produced are just some of the questions we'll answer here.Īfter more than eight years of research, testing, and trials, the Bulova Accutron hit the market in 1960. But, finally, what interests us most here, is the first fully electronic watch in the world - the infamous Bulova Accutron. To name just a few: one of the first waterproof watches, one of the first full line of ladies' watches, the first-ever national radio and TV commercials. And, it was only the first of many Bulova's firsts, an epithet that most precisely describes what Bulova stands for in the watchmaking world. The initial years of development and preparation resulted in the first-ever standardized mass production watch plant. A brief history of the Bulova watchīulova watches history dates way back to 1875, when Joseph Bulova founded the company. Thus, to avoid any potential confusion on the matter, let's start the Accutron overview by reminding ourselves briefly of the history of Bulova, the outstanding watchmakers whose expertise and revolutionary ideas led to Accutron in the first place.
