With the launch of its first watch in 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.


In developing its own wristwatch Casio began with the basic question, “What is a wristwatch?” Rather than simply making a digital version of the conventional mechanical watch, we thought that the ideal wristwatch should be something that shows all facets of time in a consistent way.



Based on this, Casio was able to create a watch that displayed the precise time including the second, minute, hour, day, and month – not to mention a.m. or p.m., and the day of the week. It was the first watch in the world with a digital automatic calendar function that eliminated the need to reset the calendar due to the variation in month length. Rather than using a conventional watch face and hands, a digital liquid crystal display was adopted to better show all the information. This culminated in the 1974 launch of the CASIOTRON, the world’s first digital watch with automatic calendar. The CASIOTRON won acclaim as a groundbreaking product that represented a complete departure from the conventional wristwatch.


Casio had since moved forward to a new focus – CMF: colour, material and finishing. The pursuit of color, material development and finishing touches has brought Casio’s product to a high degree of perfection and led this evolution into a new realm. This concept had inspired Casio’s brand, G-SHOCK, to offer innovative materials like the carbon core guard, while offering convenience and functionality for all of our diverse users’ lifestyles, alongside technologies like Smartphone Link and Tough Solar among others.
