This product is excluded from voucher codes. Introducing the cutting-edge fusion of form and function with the MTG-B4000 where advanced metal components merge with the original G-SHOCK resin to redefine rugged sophistication. The MTG-B4000B-1A2, is a breakthrough in watchmaking that redefines strength and elegance. At its core is an evolved Dual Core Guard structure, made possible through advanced AI-assisted design and a newly engineered frame that seamlessly fuses carbon fibre with stainless steel. This revolutionary exterior achieves a perfect balance between durability and aesthetic sophistication, pushing the boundaries of modern design. This timepiece represents a true collaboration between artificial intelligence and human ingenuity. Starting from concepts envisioned by skilled designers, AI technology conducted in-depth analysis and 3D simulations to optimize structural integrity and aesthetics. The resulting prototype was then meticulously refined by master artisans, resulting in a timepiece that unites functionality and beauty in a way only human touch can achieve. The complex, multi-dimensional frame is crafted from laminated sheets of carbon and glass fibre, producing a distinct layered texture. Complementing this are stainless-steel bezel elements, finished with a combination of hairline brushing and mirror polishing to create a refined, tactile visual contrast. Built to endure, this model features Triple G Resist technology, providing resistance to shock, centrifugal force, and vibration. The case is further reinforced by a uniquely contoured case back, produced via metal injection moulding (MIM), a precision method using fine metal powder for high-strength results. In this model, the MTG-B4000B-1A2, there is a newly developed blue-grey ion plating enhancing the bezel and other stainless-steel components, adding a modern edge. Every detail is crafted with exacting precision—from the high-transparency sapphire crystal to the finely machined dial, produced using advanced processing techniques at Yamagata Casio. More than just visually striking, this watch is equipped with practical innovations for everyday performance. Sync it with your smartphone via Bluetooth® using the CASIO WATCHES app. Stay on time and on course with Multiband 6 radio timekeeping, Tough Solar charging, and a high-brightness LED light—ensuring peak performance wherever your journey takes you.

FEATURES
Co-creating with AI to break new ground in toughness-driven design: Original new structure incorporating a frame made with a combination of materials
The structure and exterior design were developed collaboratively by human designers and AI, creating a bold new frame that integrates carbon fiber and metal materials. Paired with the Dual Core Guard structure, this innovation further elevates MT-G toughness and cutting-edge design. A novel approach integrates band connection parts directly into the frame, effectively reducing shock transmission to the case through a hybrid carbon-metal structure. To further enhance impact resistance, a screwless design securely attaches the metal lug components to the carbon frame, ensuring exceptional durability and resilience.
AI-assisted development process
AI was used to analyze and simulate base designs created by human designers. Drawing on the extensive data on shock-resistant structures in the G-SHOCK world, optimized 3D prototypes were generated to meet specified structural strength and material property requirements. These prototypes were further refined via repeated manual adjustments, achieving unique forms that seamlessly combine functionality and beauty.
Multi-layered carbon frame design for a side view exuding strength and beauty
The frame is cut out from a base material consisting of laminated carbon and glass fiber sheets to create its intricate, dimensional form. The beautiful layered patterns created by the pair of different materials are incorporated as a design feature. Configured to interlock with the bezel, side buttons, and case back, it offers a beautiful side view accentuating the combination of materials.
* The exact pattern on the bezel will vary by watch due to the characteristics of the molding technique, which mixes carbon fibers, resin, and other materials.
Meticulous metal finishing for a solid luster
Sallaz polishing is applied to certain mirror-polished surfaces to create smooth, beautiful, distortion-free finishes. Separate hairline and mirror finishes applied to individual components accentuate the beauty of the metal with looks of luxe refinement.
Metal injection molding (MIM), a method of metal processing in which fine metal powder is injected into molds, is used to create the intricate dimensional case back.
Newly developed blue-gray IP is applied to the MTG-B4000B.
DETAILS
Multi-layer dial projecting sophisticated refinement
The design incorporating three-dimensional arrangements of components, including a slanted dial ring set off with large, boldly raised indexes, gives the watch an impressive sense of depth. Phosphorescent finish and metallic vapor deposition are applied to the sharp, multifaceted forms of the indexes. Achieved with the fine processing technologies of Yamagata Casio, the intricate forms of the components accent the watch with sophisticated textural appeal down to the finest details.
TRIPLE G RESIST Passion for delivering further strength
The updated MT-G Dual Core Guard structure protects the carbon fiber-reinforced resin inner case with metal components, delivering high strength and weight reduction at the same time. The innovative construction meets stringent G-SHOCK standards, providing protection from shock, centrifugal force, and vibration with Triple G Resist technology.
Solar-powered timekeeping with Bluetooth® and radio control for enhanced accuracy and reliability
Super Illuminator (high-brightness LED light) for maintaining watch readability in the dark
