Casio MTG-B4000B-1A2ER Blue Gray
The Casio MTG-B4000B-1A2ER Blue Gray represents the pinnacle of G-Shock innovation, combining AI-optimized structural beauty with extreme durability. The latest addition to the MT-G series utilizes an updated Dual Core Guard structure, uniquely integrating carbon fiber-reinforced resin and stainless steel. The watch's case is born from a unique collaboration between human and artificial intelligence: AI analyzes and simulates thousands of structural alternatives to create an optimal 3D prototype, perfected by human hands. The layered carbon fiber and fiberglass bezel creates a stunning visual pattern on the side profile, communicating the watch's strength.
Technically, the watch is equipped with Triple G Resist protection, meaning exceptional resistance to shocks, centrifugal force, and vibration. Special attention has been paid to the aesthetics: the steel components are coated with a new blue-gray ion plating (IP) and finished with Sallaz polishing for a flawless reflection. The multi-layered dial, non-reflective sapphire crystal, and the precision achieved at Casio's Yamagata factory in Japan make this watch a true masterpiece. Smartphone connectivity, Tough Solar charging, and Multiband 6 radio signal ensure that the watch is always on time and ready for all your adventures.
All Casio watches come with a two-year warranty and are delivered in the brand's original packaging. Kulta-Aika is an official Casio watch retailer.
