Brand heritage

Casio began in Tokyo in 1946 as Kashio Seisakujo, founded by Tadao Kashio, and became famous for its electronic calculators. In 1974 it entered the watch market with the Casiotron, the first wristwatch with a fully automatic calendar that adjusted for the different lengths of each month. The Casiotron name was used on Casio's early digital watches through the late 1970s, and these pioneering pieces are now prized by collectors of early electronic watches.
