The CQ-1 combination clock-calculator

This popular, personal-sized digital clock with innovative functionality debuted in 1976. Designed to accommodate people's daily schedules, starting with getting up in the morning, the CQ-1 featured a unique combination of four functions: time display (a clock); time memory (an alarm); time measurement (a stopwatch); and time calculation (a calculator). This memorable product served as a launching pad for subsequent Casio combined-function development.

Retro pop colours and design

Choose from a trio of retro pop hues selected from the original CQ-1 colour lineup: red, yellow, and white. Design pays homage to the CQ-1 with multicolour accents, the typeface used for mode indicators, and more. A green-hued negative LCD mimics the look of the vacuum-fluorescent displays that calculators had at the time.
