Take a step back to 1976 with a timepiece that pays homage to the world's first multifunctional digital watch, the Casio CQ-1. The revolutionary CQ-1 - a clock, alarm, stopwatch and calculator all in one - garnered so much affection. Casio is now reviving this 70s design in the form of a timepiece, bringing the original CQ-1 colour schemes to a trio of iconic CA-500 models equipped with an eight-digit calculator function. 70s flair meets contemporary style for a timepiece that is as eye-catching as it is nostalgic. A popular digital watch in a personalised format with innovative functionality. Designed to support people's daily routines from the moment they get up, the CQ-1 offered a unique combination of four functions: Time display (clock), time storage (alarm), timekeeping (stopwatch) and time calculation (calculator). This memorable product served as a launch pad for the development of later Casio innovations with combined functions.
