A look back to 1976 with a watch that pays homage to the world’s first multifunctional alarm clock/calculator, the Casio CQ-1.
The revolutionary CQ-1, an all-in-one clock, alarm, stopwatch and calculator, was particularly loved.
Casio now reinterprets this ’70s design in watch form, inheriting the color schemes of the original CQ-1 for a trio of iconic CA-500 models featuring the eight-digit calculator function.
The vintage touch of the 70s meets contemporary style for a timeless watch.
CQ-1
A popular personalized digital alarm clock with innovative features. Designed to plan your day’s tasks in the morning, the CQ-1 featured a unique combination of four functions: time display (clock); time memorization (audio reminder); measuring time (stopwatch) and calculating time (calculator). This unforgettable product was the springboard for the development of subsequent Casio innovations with combined functions.
