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 color 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.
