Casio: A History of Innovation, Technology & Timekeeping
The History of Casio: From Calculators to Watchmaking Icons
Few brands have made such a lasting impact on everyday technology as Casio. Known today for everything from retro digital watches to the famously tough G-SHOCK, Casio has built a reputation for innovation, functionality and distinctive design.
But Casio's story didn't begin with watches. From a small workshop in post-war Japan to becoming a global electronics and watchmaking name, the brand has consistently challenged what technology can do.
From a Tokyo Workshop to Calculator Pioneer
Casio's story began in 1946, when Tadao Kashio founded Kashio Seisakujo in Tokyo. The company initially produced mechanical components before the Kashio brothers turned their attention to electronics.
Their work led to the launch of the 14-A in 1957, which Casio describes as the world's first compact all-electric calculator. Its success established Casio as an innovator in electronics and laid the foundations for the company's future in digital technology.
Casio Enters the World of Watches
Casio brought its expertise in electronics and miniaturisation to watchmaking in the 1970s.
The brand's first watch, the Casiotron QW02, launched in 1974, featuring a digital display and automatic calendar. As Casio continued developing watches, it introduced features including alarms, stopwatches, world time and calculator functions.
Rather than following traditional watchmaking conventions, Casio used technology to rethink what a wristwatch could do.
The Birth of G-SHOCK
Casio's biggest watchmaking breakthrough came in 1983 with the launch of the original G-SHOCK DW-5000C.
Engineer Kikuo Ibe wanted to create a watch capable of surviving significant impacts. After years of development, Casio introduced a shock-resistant construction designed to protect the watch's internal module.
G-SHOCK challenged the idea that watches needed to be delicate. Instead, it became synonymous with toughness, durability and functionality.
From Tough Watch to Cultural Icon
G-SHOCK continued to evolve, introducing new shapes, technologies and specialist models. The FROGMAN arrived in 1993 with a focus on diving, while BABY-G followed in 1994 with a smaller interpretation of the shock-resistant concept.
Over time, G-SHOCK became more than a practical tool. Its bold designs and unmistakable aesthetic helped transform it into a global fashion and cultural icon.
Casio Watches Today
While G-SHOCK remains one of Casio's most recognisable names, the brand's watch portfolio extends far beyond it. Today, Casio continues to create classic digital watches, analogue designs, outdoor timepieces and technologically advanced models.
Its enduring appeal comes from combining innovation, practicality and distinctive design. Contemporary G-SHOCK models also continue to draw inspiration from the original DW-5000C and DW-5600 while incorporating modern materials and technology.
Why Casio Continues to Stand Out
From pioneering electronic calculators to redefining the digital watch and creating G-SHOCK, Casio has consistently challenged convention.
The brand's history is ultimately one of experimentation and innovation, proving that a watch can be practical, technologically advanced, durable and stylish all at once.
