Great watch, it’s not as big as other G-Shock models and sits comfortably on the wrist. I appreciate its understated design, which in my opinion looks much better than some of the more extreme variants. Nice extras like solar and Bluetooth. Overall, the watch has plenty of functions that I haven’t figured out yet – the operation can be a bit complicated. I recommend it to everyone.

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.
In addition, the watch is equipped with: 5 daily alarms, an expanded calendar, a stopwatch with a measurement length of up to 100 h and accuracy of 1/100 s, and a countdown timer for up to 24 h. The world time function allows you to read the time 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 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.

I've been using it for about a year and a half, I bought it elsewhere but wanted to share my opinion. The watch looks excellent and the build quality is also at a high level! It’s not as bulky as standard G-Shocks, which makes it not look silly on my slim wrist. It works flawlessly, and another plus is the solar panel. I won’t go into detail about the functions – everyone can check for themselves. All in all – I definitely recommend it!
