The Casio G-Shock GA-B2100-2ADR updates the iconic octagonal “CasiOak” design with advanced functionality and a sleek blue finish. Inspired by the original G-SHOCK, this model combines retro styling with modern innovations like Tough Solar power and Bluetooth® Smartphone Link, delivering both style and performance.
Built with a Carbon Core Guard structure and resin band, the GA-B2100-2ADR is lightweight at just 52 g yet tough enough for daily wear and outdoor adventures. With 200M water resistance, shock resistance, and essential G-SHOCK features such as World Time, stopwatch, countdown timer, and multiple alarms, it’s designed for all-around reliability.
The double LED Super Illuminator ensures visibility day or night, while solar charging and power-saving features provide up to 18 months of operation on a full charge. Slim at 11.9 mm, this model is as comfortable as it is durable — a perfect balance of fashion, function, and toughness.
