"CITIZEN" is a maker whose predecessor was Shokosha, which started making pocket watches in 1918. The name has a wish to be familiar to the citizens. Known as a pioneer in radio-controlled wristwatches and photovoltaic power generation, the Atesa Satellite Wave, which pioneered time correction using satellite radio waves, is a masterpiece that boasts the world's shortest correction time using GPS radio waves.
