Citizen Eco-drive watches have been around in the US since 1995, when the technology first appeared. This technology, designed and utilised by Citizen Watch company, is a technology that allows for light-powered watches, which are very pricey to build but generally used for how ecological they are. They are considered to be a very prestigious brand of watch.
Citizen's primary make of watch sold is light-powered. These watches have a tiny titanium lithium-ion battery that may be charged by a silicon solar cell. This is well known as being a high quality battery as the utilization of titanium in it stops it from staying captive to the charge-discharge cycle that many batteries have. The life of an absolutely charged battery varies a big amount between different watches in the line, at anywhere from 30 days to 20 years. Many versions have a "hibernate " mode if the watch is kept in the dark for too long, which suggests that the crystal will continue to keep time but the hands won't move. When the battery is charged again, the hands will move back to the position where they need to be. According to certain independent tests, these batteries are so top quality that even after twenty years of constant use they have still got a 80% capacity for charge.
Aside from this, there are not many variances of eco-drive technology. A couple of the main ones involve a watch that's powered and charged by the motion of the wearer's wrist, and a watch that's powered and charged by the temperature difference between the wrist and the surroundings. These both implement the same technologies as discussed before for battery charge lifespan and hibernation. For the thermo versions, in hot environments the watch will not generate electric power, so to save energy ; they can move the second hand in ten second increments. A recent variation of watch that was highly publicized also uses both motion and a solar cell. Some latest versions also have a backup battery, which can allow the watches to run even in the rare case the other power source and battery both run out.
Citizen is recognized as a world leader in watch making, and Eco drive technology has boosted sales noticeably, causing Citizen to be recognised as the UK's watch make of the year, four years running.
