Take a step back to 1976 with a timepiece that pays homage to the worlds 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.
