The best of these is Citizen Eco-Drive technology. Eco-Drive watches have dials that are translucent, although they look like ordinary watch dials. Any light, even indoor light, passes through the dial into a solar receptor. Power is stored in a rechargeable titanium lithium-ion battery, so that the watch doesnt require constant exposure to light. Fully charged, Citizen watches. powered by Eco-Drive will run for several months without exposure to light.So if quartz watches are more robust, more accurate and cheaper than automatic watches, why would anyone buy automatic watches? Gerd-R Lang, a German watchmaker who heads Chronoswiss, coined a slogan for his company that encapsulates our attraction to automatic watches: ;Faszination der Mechanik;, roughly translated as a fascination with things mechanical, particularly micro-mechanics. Automatic watches are mechanical watches, powered by a spring which when wound up, transfers power, through a regulating mechanism, to a series of gears which eventually turn the hands which display the time on the dial of the watch. It is an absolutely fascinating piece of machinery, often incorporating several hundred tiny parts.The term automatic is sometimes erroneously used to describe all mechanical watches, but it is only the most common type of mechanical watch. designer_replica Rado R12636113 Men's watch is called automatic, because it is self-winding. A small rotor on the back of the watch spins around, with any movement you produce while wearing, or gently shaking the watch, and while doing so, winds the mainspring. Other mechanical watches, called manual-wind, or hand-wind, need to be wound manually.Good quality mechanical watches, while relatively fragile, should last more than a lifetime is properly maintained. It is rare to see a quartz watch not get thrown out after a few years, but there are a lot of mechanical watches around that are 50 or even 100 or more years old.While quartz watches are just one more piece of electronics, in danger of being replaced by newer technologies such as cell phones, the mechanical watch is a link to our past. While mechanical watches are now produced by high-tech machinery, their basic technology is several hundred years old. And if the watch survives, it will be because of our fascination with this ancient technology designer_replica Rado R12636113 Men's watch.
