foThe revolutionary CQ-1, a watch, alarm, chronograph and calculator all in one, attracted a lot of attention.
Now, Casio revives this 1970s design in watch form, transferring the colour schemes of the original CQ-1 to a trio of iconic CA-500 models equipped with an eight-digit calculator function.
Vintage 70s flair meets contemporary style in a watch that is as appealing as it is nostalgic.
CQ-1
A popular custom-sized digital watch with intuitive functions. Designed to accommodate users' daily schedules from the moment they woke up in the morning, the CQ-1 featured a unique combination of four functions: time display (clock); time memory (alarm); time measurement (chronograph); and time calculation (calculator). This memorable product served as a launch pad for the development of the following Casio combined-function innovations
