Casio Computer Co., Ltd was founded in 1946. In 1957, Casio introduced the world’s first entirely electric compact calculator. Casio is a Japanese multinational electronics manufacturing company headquartered in Japan. Casio watches quickly became a hit after their release in 1974. The Casio company was pioneering the mass production of quartz watches, which were run electronically. These were the world’s first successful electronic watches, and they were the height of fashion and technology. This first product was called the Casiotron and it sold like wildfire. The watch was innovative and trendy, with a small computer screen that allowed the wearer to not only accurately tell the time, but also tell the date too. These functions might be taken for granted today. In 1970s, this was groundbreaking technology.
