The Eco-Drive watch runs solely on the power produced by light from any source. By utilizing the mechanism of a solar panel and a charging device, light is converted into energy that ensures normal performance even in deficient light conditions. Such advanced technology in using light, both natural and artificial, to power a watch has brought to reality an ultimate vision that is Eco-Drive, the Light Powered Watch.
The secret of Eco-Drive lies in its reserve battery. The device, which contains no such toxic elements as mercury, acts as a reservoir to store the energy converted from light. When fully charged, the watch can run on this energy from 4 months to 5 years, depending on its model. The Citizen Eco-Drive incorporates this hassle-free handling into an entire range of functions, from the simplest in 3-hand movement to the most sophisticated, such as perpetual calendar and minute repeater, etc. Recently, radio-controlled technology has even been developed. All these, combined with the omission of battery replacement, underscores Eco-Drive friendliness to ecology, as well as to its users.
