Casio G-Shock Metal Covered GM-2100B-3AER watch

Rugged and waterproof sports watch designed to resist shocks, with reliable quartz movement. Featuring a black octagonal case crafted from a fusion of steel and carbon fiber. The watch offers an analog-digital display with a striking green dial, enhanced by LED backlighting and a Neobrite coating for easy readability in low-light conditions. The backlight is conveniently activated via a dedicated side button. Durable mineral glass protects the dial and boasts a fifth-degree rating on the Mohs hardness scale.

Durable construction

Incorporation of the G-Shock system significantly improves the watch's resistance to impact and mechanical damage. Boasting exceptional water resistance, the model is capable of withstanding immersion up to 200 meters (20 bar), making it suitable for use during swimming as well as diving.

Equipped with a Miyota quartz movement and powered by two SR726W batteries, the watch delivers precise timekeeping for up to 3 years of uninterrupted use. Time is presented in both 12 and 24-hour formats for operational flexibility. Five daily alarms with an integrated snooze feature, a comprehensive perpetual calendar, a stopwatch measuring up to 100 hours with 1/1000 second precision, and a countdown timer of up to 24 hours enhance readiness. The world time function offers instant access to various time zones for strategic coordination.

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.

    Fantastic timepiece. Durable, beautiful, waterproof - I shower with it on, it can be submerged up to 200 meters, it's a bit tricky to set up with the manual but it works, you don’t have to take it to a watchmaker. It has all the world times in memory and you can set the digital clock, then give a command to set that time on the hands on the dial. Setting the days of the week was harder but everything worked out and I'm very satisfied, it's unique and excellent. It also has the date. I recommend it. Everywhere else it was more expensive, here it’s the cheapest, if you still have ksk points – get it!

    Great watch, you practically don’t feel it on your wrist, the dial is legible with options to customize it (hour and date system). I recommend it to anyone looking for a good-looking watch that can withstand a bit more than classic watches.
