Waterproof and shockproof sports watch with quartz movement. The octagonal case is styled after the Japanese manufacturer's first G-Shock model, launched in 1983.

The watch's mechanism is enclosed in an internal Carbon Core Guard case, made of carbon-reinforced resin. Rugged construction combined with the G-Shock system ensures high resistance of the watch to shock and mechanical damage. The model is characterized by high water resistance and is resistant to immersion up to 200 meters (20 bar), which allows safe use while swimming and even diving.

Comfortable wearing of the watch on the wrist is ensured by a strap made of flexible plastic, fastened with a metal buckle. The material used is resistant to the damaging effects of moisture and sweat, making it ideal for various activities.

The dial with hands and display allows digital-analog time reading, and the time is displayed in 12/24-hour format. Dual LED backlighting and Neobrite fluorescent material coating of the hands allow the watch to be operated in low light or no light at all.

Thanks to the Bluetooth system, the watch can be connected to the Casio Watches app on your phone, allowing you to automatically adjust the time, set alarm clocks, timer and reminders, as well as manage watch settings. In addition, the app allows you to find a lost phone with the help of the watch.

Additionally, the watch is equipped with: 5 daily alarms, an advanced calendar, a stopwatch with a measurement capacity of up to 100 hours and an accuracy of 1/100 second, as well as a timer counting down from 1 second to 60 minutes. The world time function allows the current time to be displayed in 31 time zones.

The watch is powered by sunlight using the Tough Solar function - fully charged, it can work for up to 7 months without access to light.

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 cult status thanks to its exceptional resistance to shocks, water and extreme environmental conditions. Casio continually develops its technologies, introducing features such as Tough Solar – a solar-powered system, and Wave Ceptor – time synchronisation by radio waves, which ensures precision and reliability in operation. Watches from this brand are popular both with professionals and with 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, underwent a drop test from the tenth floor and continued to work flawlessly, which became the foundation of the series' legend. Casio is now synonymous with innovation, reliability and timeless design.

    The watch is incredible, perhaps not the most informative due to the backlight solution, but the appearance is simply amazing. The order arrived in 3 working days; I paid on Saturday and already received it on Wednesday. I was very worried about the delivery, but everything was fine. The only thing I didn't understand was why there was no protective film on the glass.

    G-Shock is always a solid choice – you don’t have to worry about damage during various activities. This model is particularly stylish and slim, smaller than typical, bulky versions. I had doubts about its legibility, but it works brilliantly.

    Great watch, stylish. Small and lightweight. Thank you for the fast delivery and good price. Simple settings, solar battery, Bluetooth, and excellent quality.

    This is already my next G-Shock model. They are not only reliable and practically indestructible, but also really nice visually. I appreciate their sporty-military, but toned-down design. I’m sure I’ll buy another Casio someday.

    A typical Casio G-Shock. The definite advantage is solar charging. The readability is at a decent level. The backlight and fluorescence make it easy to read. The strap is comfortable to wear. I definitely recommend it.

    I was looking for a sports watch for a long time and chose this model. It has all the features I need, without unnecessary frills: solar charging, phone locator, water resistance, Bluetooth. The dedicated app works smoothly and connects to the watch without issues.

    I give it 5 stars. I’ve been using the watch for a few days and confirm that the solar charging works correctly. It is smaller than a typical G-Shock, which in my opinion is an advantage. It’s suitable both for trips and elegant dinners. Best regards.

    G-Shock is top of the range. Very durable and will last for many years. In this stealth version, the look slightly affects the readability of the dial, so it’s worth keeping this in mind when choosing a colour.
