A sports watch with a quartz movement that is waterproof and shock-resistant. A black octagon-shaped watchcase made of a mix of steel and carbon fiber. The green analog-digital dial has LED backlight and a Neobrite coating, allowing easy reading of the time in the dark. The backlight is manually activated by a button located on the side of the watch. The dial is protected by mineral glass with a fifth-degree hardness on the Mohs scale.

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.

    An excellent watch – durable, stylish, and waterproof. I use it in the shower without issues, and it can be submerged up to 200 meters. Initially, setting it up with the instructions may be a bit complicated, but everything works correctly and you don’t need to take it to a watchmaker. It has world time memory and allows you to set digital time, which can be switched to the hands. Setting the days of the week is a bit trickier, but in the end everything worked out and I am very satisfied. The watch is exceptional and also has a date display. I recommend it, because I couldn’t find it cheaper anywhere – if you have KS points, it’s worth taking advantage!

    Great watch, almost unnoticeable on the wrist. The dial is clear and can be customized (you can choose the time and date format). I recommend it to anyone looking for a solid and stylish watch that will last longer than typical models.
