Citizen® is recognized as a worldwide leader in advanced technology. From the world’s slimmest LCD watch to the first voice recognition watch and the world’s first professional dive watch with an electronic depth sensor, Citizen’s record of “world firsts” is unmatched. Founded in 1918, Citizen has proudly embraced a multicultural style and influences in creating their exceptional designer watches. The most important breakthrough for Citizen watches involved solar power. A Citizen watch called the Crystron Solar Cell was the world’s first solar-powered analog quartz watch.
