![]() If watches are most valuable for the connections they make between our present, the past, the future, and the world around us, I think there's a lot to be said for all the dots connected by the new Accutron watches. That may sound like a lot of freight for a watch to bear, but I can't look at these guys without remembering the last time – many months ago – that I was able to visit Tokyo and wander through the neon riot of Shinjuku, deeply grateful to be there. These watches evoke that world for me as well, and also a world in which travel is an essential and indispensable part of human education and experience. The new Accutrons are silent acoustically, but they speak in their own way to a very particular and very special time in horology, when the future seemed a place of unlimited potential, and not just the Earth, but the sky and even other worlds were the limit when it came to travel. It is the smallest tuning fork model ever produced with a frequency of 480 Hz. The small diameter of 19 mm made this movement suitable for use in ladies watches. VINTAGE MENS BULOVA ACCUTRON WRIST WATCH, CAL. On 11 August 1970, the Bulova Watch Company Bienne-branch presents thefirst 'Mini Accutron' to the international press. ![]() My father had an Accutron watch, which he bought around 1970, and it was fascinating to me, at the time, to put it to my ear and hear that distinctive 360Hz hum. Bulova Accutron 218 Tuning Fork Vintage Watch Round GF 1976 Men 34mm USA. I wrote about nostalgia, not too long ago, in the context of monopusher chronographs, and while the drive technology in the Accutrons is new, they are also a surprisingly poignant exercise in nostalgia as well. When you turn the motor on, current passes through the rotor, creating a magnetic field, and the attraction and repulsion of the induced magnetic field in the rotor, and the magnetic field in the stator, causes the rotor to turn. ![]() A standard electric motor has two basic components: These are the rotor, which rotates, and the stator, which doesn't usually the rotor is inside the stator, which is either composed of permanent magnets, or coil-wound electromagnets. ![]() The stepper motors in a conventional quartz watch, which get their name from the fact that they move the hands in incremental, discrete steps, rather than in a smooth unbroken motion, are despite their tiny size still basically conventional electric motors, which rely on electromagnetic interactions. The electrostatic drive system in the new Accutron watches – there are at launch two models, the Spaceview 2020 and the Spaceview DNA – use the attraction and repulsion of electrical charge in order to both generate electrical current and to generate mechanical energy. ![]()
