Shock-resistant and waterproof sports timepiece featuring a reliable quartz movement. The octagonal case draws inspiration from the original 1983 G-Shock by the renowned Japanese brand.

A robust inner Carbon Core Guard protects the watch mechanism, housed within a carbon-reinforced resin case. The sturdy engineering, enhanced by the G-Shock system, guarantees exceptional resistance to impact and mechanical stress. High water resistance is a key attribute, with the watch enduring submersion up to 200 meters (20 bar), making it suitable for swimming and diving activities.

Superior wearing comfort comes from a flexible strap, secured with a metal buckle. The chosen material is impervious to moisture and sweat, ensuring suitability for a variety of sporting pursuits.

A combination of hands and digital display allows for digital-analog time representation, supporting 12/24-hour formats. Dual LED backlighting along with fluorescent Neobrite on the hands ensure legibility in low light or complete darkness.

Equipped with Bluetooth connectivity, the watch pairs with the Casio Watches mobile app for features like automatic time sync, alarm and timer settings, reminders, and watch customization. The app also includes a function to locate your phone using the watch.

Additional functionalities incorporate 5 daily alarms, a comprehensive calendar, a stopwatch with up to 100 hours capacity and 1/100 second accuracy, and a timer counting down up to 24 hours. The world time feature enables access to time in 31 different time zones.

Solar technology powers the watch via Tough Solar; fully charged, operational autonomy extends up to 7 months without exposure to light.

Casio is a Japanese brand founded in 1946, which has remained one of the most recognizable consumer electronics manufacturers in the world for decades. It gained global fame with its iconic G-Shock series from the 1980s, valued for its high resistance to shocks, water, and extreme conditions. The company consistently develops its technologies, introducing innovations such as Tough Solar - a solar power system - and Wave Ceptor - radio time synchronization. Casio watches are popular among professionals and people looking for reliable models for everyday use and outdoor activities. The first G-Shock (model DW-5000C), designed in 1983 by engineer Kikuo Ibe, was so durable that it was tested by dropping it from the tenth floor, and yet it still worked flawlessly. Today, Casio is a symbol of innovation, durability, and timeless style.

    This is already my next G-Shock. Besides being reliable and indestructible, they are simply very nice. I like this sporty-military style, but without weirdness. This is definitely not my last Casio watch.

    Simply Casio G-Shock. Big plus for the solar battery. Fairly readable. The fluorescence and backlight are sufficient for reading. Comfortable strap. I recommend it.

    I was looking for a sports watch for a long time and decided on this one. It has all the options I wanted without unnecessary frills: solar battery, phone finder, waterproof, Bluetooth. The dedicated app works efficiently and connects with the watch without any problems.

    I give 5 stars. I've had the watch for a few days, tested the solar charging and it works. The watch is smaller than the standard G-Shock, which I consider a plus. In my opinion, you can wear it both for survival trips and a romantic dinner. Cheers!

    G-Shock is a class of its own. Indestructible. A watch for years. In this variant, you lose a little readability for the stealth look. It's worth remembering this when choosing the color version.
