Casio developed its first calculator in 1957, but it was not until 1974 with the release of the Casiotron that Casio entered the watch making a market. The Casiotron capable of displaying dates with an automatic update for long and short months, and automatic adjustment for leap years, was a good first step into the market.

Casio also makes products for local markets, including a 'Prayer Compass' watch designed to help Muslims pray on time and in the right direction.

In the 1970s and 80s, Casio was known for its electronic (including scientific) calculators and digital watches. Today, Casio is most commonly known for large, durable watches. Especially popular are its dual function (LCD and analog) watches, some of which, including Wave Ceptor and Pro Trek / Pathfinder series, receive radio signals daily from an atomic clock to keep accurate time. Casio made a variety of digital watches with inbuilt games in the 1980s and 90s, which were highly popular.
