The Casio Story

Casio's first hit was a ring. In 1946 Toshio Kashio designed a finger ring that held a cigarette for hands-free smoking, and his older brother Tadao turned the rings on a lathe in the Mitaka, Tokyo workshop he opened that April. The ring paid for calculators: the 14-A of June 1957 did 14-digit arithmetic with 341 relays instead of gears, and Casio Computer was incorporated that month to build it.

The Casiotron QW02 of November 1974, its first watch, had a calendar that knew which months ran 30 days and which 31, a first by Casio's account. In 1981 engineer Kikuo Ibe, who had broken a watch from his father, set a target: a 10-meter drop, 10 bar of water pressure, 10 years on one battery. A bouncing rubber ball gave him the answer, a module floating inside the case, and after more than 200 prototypes the first G-Shock, the DW-5000C, went on sale in April 1983. The CD-40 Databank of 1984 put a phone book on the wrist.

Digital from the start, Casio grew through the quartz years and shipped its 100 millionth watch in 1984. The reckoning came later, not in watches. Its QV-10 digital camera of 1995 sold 200,000 in a year, Casio says; smartphones ate that trade, and Casio quit consumer cameras in 2018. Watches carried the company. A hundred million G-Shocks had shipped by August 2017, over 160 million by Casio's 2025 count, and in the year to March 2026 watches brought in 185 of Casio's 276 billion yen in sales and more operating profit, 27 billion yen, than the group's 23 billion.

Headquarters are in Shibuya, Tokyo; Kazuhiro Kashio of the founding family is chairman, with Shin Takano president since June 2025. In July 2025 Casio released its first mechanical watch, the Edifice EFK-100, and in November the ring-sized G-Shock nano. The square DW-5600 G-Shock and the 1989 F-91W are still made, so a 1980s Casio here, identified by the module number on its case back, usually has a descendant in the catalog.
