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.

Edifice watches range from basic chronographs to more advanced models with more computerized movements. Many Edifice watches utilize 'Tough Solar', Casio's name for light chargeable batteries. More advanced models are 'Waveceptors' and can calibrate themselves with atomic clocks via radio waves.
