A beautiful, original G-Shock piece. Besides being reliable and virtually indestructible, they're just very attractive. I like this sporty-military style without any unnecessary extravagance. This is definitely not my last Casio watch.
Shockproof and waterproof sports watch featuring a quartz movement. The analog-digital face is outfitted with an Auto-LED backlight and a hand shift feature that moves the hands aside with a button press, making the LCD screen easier to read. The Super-Illuminator backlight can be switched on manually or automatically by raising the wrist and bringing the watch towards your face. The dial is protected by mineral glass known for its fifth-level Mohs scale hardness.
The G-Shock GBA-900 series is compatible with other devices via Bluetooth, enabling control of functionalities such as a pedometer, step tracking with five levels of workout intensity, calorie counting, stopwatch log, 'find phone' tool, call notifications, automatic time synchronization (four times per day), and world time covering nearly 300 cities.
Integrating the G-Shock system enhances resistance to impacts and mechanical disturbances. The model offers high waterproofing and withstands submersion up to 200 meters (20 bar), which permits safe operation during swimming and diving. Additional protection against magnetic influence is provided, in line with ISO Standard 764.
Time is displayed in 12/24-hour formats. Additional features include: five daily alarms with snooze function, advanced perpetual calendar, precise stopwatch (1/100 s accuracy), timer up to 24 hours, and a dual time feature. The world time option enables tracking time across multiple time zones.
Powered by a CR2025 battery, the model offers up to 2 years of battery life as stated by the manufacturer. The watch comes equipped with a comfortable silicone band, adjustable in circumference with a buckle closure.

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.

Very nice watch. The first impression is good build quality, attention to detail, and very comfortable. Many functions, such as LED illumination of the dial, automatic setting of the hands via a smartphone app, and others. The app itself is fine, has many features, including notifications of incoming messages, calls, and notifications on your phone, via sound signals in the watch. It’s not a smartwatch, but it is certainly a modern version of a standard work watch for today's times, thanks to the app :) Not everyone may like that the hands could be more visible, as well as the digital time display, but I've been using it for a few weeks now and it doesn’t bother me. So far, I am very satisfied with the purchase, I don’t have to constantly charge the watch (the battery is supposed to last 2 years, we'll see), so I can confidently recommend the proven brand CASIO, G-SHOCK models :) The only question is which model, what functions, and for how much...
