・No need for regular battery replacement. The light-powered Eco-Drive is Citizen's proprietary technology that converts sunlight or the faint light in a room into electricity to keep the watch running. Once fully charged, it will continue to work for a long time even in the dark, so there is no need for regular battery replacement. ・Always keeps accurate time. It receives standard radio waves transmitted based on an atomic clock that is said to have an error of 1 second in 100,000 years, and automatically corrects the time and calendar in four areas of the world: Japan, China, the United States, and Europe. ・Displays the time around the world in two steps. Equipped with a Direct Flight function. You can easily adjust the time to the local time of any other country.
