CA500WE-4B

Take a step back to 1976 with a timepiece that pays homage to the world’s first multifunctional digital clock, the Casio CQ-1.

The revolutionary CQ-1 — a clock, alarm, stopwatch and calculator all in one — solicited so much affection.

Casio now revives this ’70s design in timepiece form, bringing the original CQ-1 colour schemes to a trio of iconic CA-500 models equipped with eight-digit calculator function.

Vintage ’70s flair meets contemporary style for a timepiece as eye-catching as it is nostalgic.

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.
