MTG-B4000D-1A

Discover innovative form and structural beauty — MT-G timepieces that combine metal materials with the resin used in the first G-SHOCK models. The MTG-B4000D features an updated Dual Core Guard structure with a frame design integrating carbon fiber and stainless steel, which was developed with the aid of artificial intelligence trained with big data on impact resistance. A seamless collaboration between AI capabilities and human developers, this timepiece creatively integrates materials, structure, and design into an organic whole of functional beauty. Base designs created by human designers were analyzed and simulated by AI and then further refined by the human hand to render a unique form that organically synthesizes functionality and beauty. The intricate, dimensional form of the frame is cut out from a base material of laminated carbon and glass fiber sheets, creating a beautifully layered pattern. The stainless-steel components of the bezel, featuring a dual-layer design of inner and outer bezels, are polished with separate hairline and mirror finishes for a sophisticated textural look. The band also features a layered composite construction that integrates stainless steel and carbon fiber-reinforced resin. Combining the ruggedness of metal and lightness of resin, the band has a solid, substantial feel, while ensuring a comfortable fit. The watch employs the Triple G Resist structure to withstand shock, centrifugal force, and vibration. The case is also protected by the dimensional form of the case back, which is created using metal injection molding (MIM), a method of processing metal in which fine metal powder is injected into molds. Meticulous attention paid to every detail is apparent down to the sapphire crystal, which delivers high transparency. The dial incorporates delicate components featuring intricate designs achieved with fine processing technology from Yamagata Casio. This innovative, tough style delivers full-on functionality, as well. Download the CASIO WATCHES app to pair with your smartphone via Bluetooth®. With Multiband 6, Tough Solar charging system, and high-brightness LED light, these timepieces keep you at peak performance, whatever your adventures may bring.
