CQ-1

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