Casio is an electronics manufacturing company that was founded in 1946 by Tadao Kashio.

The company rose to popularity quickly after releasing its first-ever product, a cigarette holder, which proved to be a huge success. Casio became involved in 1954 when they released Japan's first electro-mechanical calculator.

The brand's timepieces are affordable and long-wearing, making them a favourite to both enthusiasts and everyday people. With the large variety of wristwatches and their commitment to progress, it is no surprise Casio has remained amongst the giants in the industry.
