MILITARY is a premium dealer of Casio.
Casio is a Japanese brand founded in 1946, known worldwide as one of the leaders in consumer electronics. A breakthrough moment in the company's history was the launch of the G-Shock series in the 1980s, which gained iconic status thanks to exceptional resistance to shock, water, and extreme environmental conditions. Casio continuously develops its technologies, introducing features such as Tough Solar — a solar-powered system — and Wave Ceptor — time synchronization via radio waves, which ensures precision and reliable operation. Watches from this brand are popular with both professionals and users looking for durable solutions for everyday use and field activities. The first G-Shock model — DW-5000C, designed by engineer Kikuo Ibe in 1983, passed a drop test from the tenth floor and continued to work flawlessly, which became the foundation of the series' legend. Today, Casio is synonymous with innovation, reliability, and timeless design.
