The Beginning of Casio
The genesis of Casio began in 1946 in Tokyo, Japan just following World War II. The company was founded by engineer Tadao Kashio, who had a passion for creating practical products that could improve everyday life.
Casio, unlike many of the famous watch brands, was not initially a watch maker. Originally the company produced mechanical parts, but later became known for developing some of Japan’s first electronic calculators.
Casio’s expertise in electronics would become one of its greatest assets. Casio did not choose to compete with the traditional Swiss watchmakers on the basis of mechanical craftsmanship alone, but rather to focus on innovation, digital technology and practical everyday features.
This innovative approach has helped the company to become one of the most recognizable watch brands in the world in just a few decades.
How Casio Entered the Watch Industry
Casio joined the watch industry in 1974 with the formal launch of the CASIOTRON.
Most timepieces at the time only showed time and date. Casio set new standards with an electronic watch that could automatically update the calendar, even during leap years.
It may seem obvious now, but this was radical in the 1970s.
The CASIOTRON had shown how digital technology could make timepieces smarter, more convenient and easier to operate.
This achievement motivated Casio to create new electronic timepieces instead of adhering to the conventional mechanical watch industry.

The Birth of G-Shock
You can’t talk about Casio without talking about the G-Shock.
In the early 1980s, Casio engineer Kikuo Ibe set out to make a watch that could take a beating and survive a fall. The goal was known as the Triple 10 Concept, requiring the watch to:
- Survive a 10-meter fall
- Water pressure resistant to 10 bar (100 meters)
- Have a battery life of around 10 years
It took years of research, but the first G-Shock was released in 1983.
Its chunky design made many people mistrust it at first, but consumers soon learned that this watch could resist conditions that killed regular timepieces.
Today, G-Shock is one of the most revered sports watch collections in the globe. Trusted by Military, Firefighters, Athletes, Construction Workers, Hikers and Outdoor Enthusiasts.
