► ARCHIVE FILE: CASIO — BRAND HISTORY
Casio began not with watches but with calculation. Tadao Kashio founded Kashio Seisakujo in Tokyo in 1946, and with his three brothers developed the 14-A in 1957, the world's first compact all-electric relay calculator, incorporating the business as Casio Computer Co. that same year. The move into watchmaking came in November 1974 with the Casiotron, a digital watch whose claim to fame was an automatic calendar that knew how many days each month had, a small feat of logic that announced how an electronics firm would approach timekeeping.
