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 cult status thanks to its exceptional resistance to shocks, water, and extreme environmental conditions. Casio is constantly developing its technologies, introducing features such as Tough Solar - a solar power system - and Wave Ceptor - time synchronization using radio waves, which ensures precision and reliability. The brand's watches are popular among both professionals and users looking for durable solutions for everyday use and outdoor 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 function flawlessly, which became the foundation of the series' legend. Today, Casio is synonymous with innovation, reliability, and timeless design.

Neobrite
Neobrite is a luminescent coating used in Casio G-Shock watches, applied to the hands and indices of the watch face. When exposed to daylight or artificial light, it glows in the dark, ensuring good readability at night. It is non-toxic, durable, and does not require battery power.
Dual Illuminator
Dual Illuminator is a lighting system used in Casio G-Shock watches that simultaneously illuminates the watch face and digital display. This ensures full readability in complete darkness. The system is activated manually or automatically (when the wrist is raised) and operates independently of external light sources...

The watch offers good quality for an affordable price. The only drawback may be the backlight operated by the LIGHT button, which is typical for G-SHOCK models, but on the other hand, the hands illuminate automatically in complete darkness.
