Since Casio's invention of the first electric calculator in 1957, the company has continued to be a forerunner in digital communication and advanced technology. Among Casio's most notable achievements is the first shock-proof watch. The Casio G-Shock premiered in 1983, designed by a Casio engineer named Kikuo Ibe. He strove to "create a watch that never breaks." And it never did break! The G-Shock remains a staple in the sports watch genre.
