The standard for modern mechanical watches is 28,800 vibrations per hour, which can also be expressed in the total number of complete oscillations per second, or Hertz – 28,800 vph is 4Hz. The first really major advance in oscillator technology for watches, and the first decisive step away from the balance and spring, was the Bulova Accutron, which debuted in 1960, and used an electronically driven tuning fork, oscillating at 360Hz. If you go to the British Museum, you can see one, by Tompion, with a 13 foot pendulum and a period of 0.25Hz). A balance can be made to vibrate fairly quickly – much more rapidly than a pendulum (pendulum clocks often oscillate once every second or two although other periods are possible. Men’s Eco-Drive Titanium Perpetual Chrono Atomic is a handsome watch for allĬheck on Amazon: Citizen Men’s Eco-Drive Titanium Perpetual Chrono Atomic 2.As a general rule, and all other things being equal, an oscillator vibrating at a higher frequency will have greater precision than one vibrating at a slower frequency. However, once you get introduced to its features, it will be easy to read and use. The bold design can look intimidating at first glance because of all the features. Like if this was notĮnough, the watch also receives signals from different timezones, with the sameĬhronograph with a tachymeter on its bezel, has a 24 hours time display, dateĪnd day window and a power reserve window. Synchronized with NASA’s atomic clock via radio signal. Technology and features that go far beyond timekeeping.
