Casio

Casio was founded in April 1946 by Tadao Kashio as Kashio Seisakujo, a small subcontracting factory in Tokyo. The company initially produced calculator parts and consumer goods. In 1957, it was incorporated as Casio Computer Co., Ltd. after developing Japan's first compact all-electric calculator. Casio entered the watch market in 1974 with the Casiotron, the world's first watch with an automatic calendar. The company's most iconic achievement came in 1983 with the launch of the G-Shock, designed by engineer Kikuo Ibe to withstand a 10-meter drop, 10-bar water resistance, and 10-year battery life. This 'Triple 10' concept revolutionized rugged watchmaking. Over the decades, Casio expanded its watch portfolio to include Baby-G (1994), Pro Trek for outdoor enthusiasts, the elegant Oceanus line, and the motorsport-inspired Edifice collection. Today, Casio remains a global leader in affordable, technologically advanced timepieces.
