Travel back to 1976 with a watch commemorating the world's first multi-function digital watch, the Casio CQ-1. The CQ-1 watch has a design that will hook you as it is a clock, alarm, stopwatch and calculator in one. Now Casio is reviving this 1970s design in watch form, evoking the original CQ-1 color schemes in three of its popular CA-500 models with eight-digit calculator function. Classic '70s flair meets contemporary looks in an eye-catching, nostalgic timepiece. CQ-1 is a popular digital watch with customizable size and innovative functions. Designed to accommodate people's daily schedules from the moment they wake up in the morning, the CQ-1 features a unique combination of four functions: time display (clock); and time memory (alarm clock); measuring time (stop watch); And time calculation (calculator). This memorable product served as a stepping stone towards the development of Casio's subsequent multifunctional innovations.
