Worn on the wrist, this device could help you tell time and do math. What is the name of this successful and popular product originating in the 1980s?

Though they didn't make the first calculator watch, the Casio line of calculator watches were definitely the most iconic and popular of the 1980s. The character Marty McFly from the movie Back to the Future helped spread the popularity of Casio calculator watches by wearing the CA-50 model in the film. Though not as popular as they were then, Casio still makes a number of calculator watches.
