With a history dating back to 1946, Japanese brand Casio is today one of the world's largest brands in watches, calculators, and cash registers. The technology behind the calculator forms the foundation for the watches, which were introduced in the 1980s. The well-known design with digital time display is for many people a symbol of the style of the 80s and 90s. Today, Casio is still one of the best-selling watch brands in the world, and many of the well-known vintage designs continue to be the most sought-after models. In addition to the classic models, the G-Shock collection, with the highest level of technology and robustness in the watch world, represents the image of modern-day Casio.
