Casio G-Shock Men’s Black GA-2100-1A2ER
A watch built to withstand time and the elements.
The Casio GA-2100-1A2ER embodies the spirit of the G-Shock collection with bold styling and unmatched durability. Designed for extreme conditions, it boasts 20-bar water resistance, making it perfectly suited for diving and intense outdoor activities. Its 45.4 mm octagonal case, both compact and robust, is made from carbon-reinforced resin — a material renowned for its lightness and exceptional strength.
Sleek, functional design
The black dial features a combined analog-digital display, with blue hands that add a touch of modernity and contrast. Protected by scratch-resistant mineral glass, the display maintains excellent legibility even on the move. With a thickness of just 11.8 mm, it offers a comfortable and discreet fit on the wrist without compromising durability.
Comfort, precision, and reliability
Powered by an accurate quartz movement, this watch delivers reliable performance for everyday wear. Its black resin strap, both supple and durable, fits the wrist perfectly thanks to a silver-tone buckle clasp. The strap width subtly tapers from 26 mm at the lugs to 19 mm at the buckle for optimal ergonomic comfort.
The Casio G-Shock GA-2100-1A2ER is more than just a watch — it’s a blend of cutting-edge technology and refined design, created for active, demanding men in search of both performance and style.
