Casio, founded in 1946, is and remains one of the leading watch brands in the field of innovation and technology. This company was one of the first to start producing quartz timepieces. Casio's best known innovation was the famous calculator watch in the 70’s. In the 80's Casio made himself immortal with the shock-resistant Casio G-Shock and Baby-G models. In addition, it was one of the first makers of radio-controlled watches. Fun fact, Casio was with Casio Edifice for many years a sponsor of the Red Bull Racing Formula 1 team.
