Waterproof and shockproof sports watch featuring quartz movement. The black case with an octagonal shape is crafted from both resin and carbon fiber. The analog-digital display is outfitted with LED backlighting and a Neobrite coating to facilitate easy time reading in low light. The backlight can be manually activated with a button on the side of the watch. The mineral glass covering the watch face has a fifth-grade hardness on the Mohs scale.
Incorporating the G-Shock system enhances the watch's resistance to impacts and mechanical damage. This model is highly water-resistant, with the capability to withstand dives up to 200 meters (20 bar), making it suitable for swimming and diving.

Time is displayed in a 12/24-hour format. Additional features include: 5 daily alarms with a snooze option, an advanced perpetual calendar, a stopwatch that measures up to 100 hours with 1/1000-second precision, and a timer counting down up to 24 hours. The world time feature enables time reading across different time zones.

The watch runs on 2 x SR726W batteries, with a manufacturer-stated lifespan of 3 years. It comes with a flexible black plastic strap, adjustable with a metal buckle.

Casio


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.

    I ordered from this store for the first time. Satisfied! Convenient ordering, package tracking, fast delivery. I bought the watch as a gift with engraving. Everything was done nicely! The watch fits perfectly on the wrist, it's not big, and it's light. I liked it.

    This watch is amazing, like most g-shock models. It wears very well and fits perfectly on the wrist. You don't have to worry about it falling apart or getting damaged when it comes in contact with water.

    I picked up the package with this watch yesterday. It was shipped immediately and after four days it was already at the Nova Poshta branch. I am very satisfied with it.

    I recommend this watch! It looks even better in person. It's stylish and fits many occasions, and the white indices have a slight grayish tint, which gives a subtle effect. It isn't too big or tall like some g-shocks. The only downsides are the weak backlight – just one diode – and the Neobrite coating is only on the hands, but overall it deserves a 5/5 rating.

    Great watch with many features. I recommend it – it's comfortable, easy to use, and doesn't make your wrist sweat. It has a traditional look and a solid build.
