Discover innovative form of great structural beauty, MT-G timepieces born of an entirely new design concept combining the resin used in the first G-SHOCK models with metal materials. Welcome to a whole new level of sophisticated structural design. With its even more advanced Dual Core Guard structure, the MTG-B3000 protects the module in a carbon fiber-reinforced resin case and encloses the exterior in metal components. Repeated pressing, cutting, and polishing builds the stainless steel case back upward into an intricate 3D form. The case back also serves as the lugs to secure the band and as the guards for crown and buttons, for a completely new structure. All of these innovative designs and technologies created a much thinner watch, measuring just 12.1 mm from bezel to case back. MT-G innovation extends even to the band. All-new one-touch exchange structure eliminates the need for special tools. Simply press the buttons located on the sides of the lugs to quickly and easily swap out the band. The MTG-B3000 features an even lighter layered composite band made of stainless steel and fine resin. Its stainless steel bezel is ion plated in gold color, then treated with a hairline finish to expose the stainless steel below the convex surfaces only. These meticulous details come together to offer an intricate and sophisticated design. The high-transparency sapphire crystal paired with the delicate molding and vapor deposition of Yamagata Casio’s microfabrication technology adds final touches of sophistication and quality. This innovative, tough new style delivers full-on functionality, as well. With Multiband 6, Tough Solar charging system, and high-brightness LED light, these timepieces keep you at peak performance, whatever your adventures may bring.
