Travel back to 1976 with a watch that pays tribute to the world’s first multifunction digital clock: the Casio CQ-1.
The revolutionary CQ-1 clock — a combination of clock, alarm, stopwatch, and calculator — earned wide affection.
Today, Casio revives this 1970s design with this watch, featuring the original CQ-1 color scheme on a trio of iconic CA-500 models, each equipped with an 8-digit calculator function.
The vintage 70s look meets modern style in a watch that's both charming and nostalgic.

A popular, compact digital clock with innovative features.
Designed to support users in daily life from the moment they wake up, the CQ-1 uniquely combined four functions: time display (clock), time memory (alarm), time measurement (stopwatch), and time calculation (calculator).
This unforgettable product was the springboard for Casio’s ongoing innovation in combined functionality.
