Quartz Clocks

Clocks are instrument that measure the time. A watch a mechanism that oscillates at a constant rate, either a pendulum, a spring or a crystal. The search for accuracy and less weight was a constant in the job of Watchmakers. If we discard the atomic clocks and timers, the quartz watches were an accurate revolution on a ancient technology.

Warren Alvison Marrison, a Canadian watchmaker, was its inventor, in 1929 in the USA.

The quartz clock was preceded by many other watches, such as the hourglass of the Middle Ages, the water clock or clepsydra used until the Middle Ages, a sundial used by the Egyptians before 1500 BC and the mechanical clock that appears in Europe in 1300. And, of course, pocket watches and wristwatches that appeared in 1504, but they are seen as luxury until in 1868 he invented the first winding watch.

Quartz watches include the famous Swatch (watches which are very simple and cheap with no possibility of repair and much used by individuals and companies as promotion at the time), Japanese watches (such as Citizen, Seiko, Casio) that feature high precision and low prices and finally the Swiss watchmakers , who are always devoted to luxury watches.

As a curiosity, quartz electric clocks, run by a temporary display by exploiting the piezoelectric property of quartz, by applying an electric field equal to the self oscillation of the crystal, 60 kHz, it oscillates with the same frequency so regular that in turn, stabilizes the alternating current, which moves the hands of a clock analog or electrodes segments that show the numbers on digital clocks
