Discover innovative form and structural beauty — MT-G timepieces that combine metal materials with the resin used in the first G-SHOCK models. Now, in the powerful form and refined elegance of carbon fiber and metal in black.

The MTG-B4000 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. The result is an innovative design that delivers both strength and beauty.

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 reevaluated and further refined by the human hand to render a unique form that organically synthesisees functionality and beauty.

The intricate, dimensional form of the frame is created from a base material of laminated carbon and glass fiber sheets, revealing a beautifully layered pattern. The bezel features a dual-layer design of inner and outer bezels, with stainless-steel components polished with separate hairline and mirror finishes, then ion-plated in black for a sophisticated textural look.

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.

The MTG-B4000BD-1A features a layered-composite band made of stainless steel and carbon fiber-reinforced resin, offering both the durability of metal and the lightness of resin. With a solid and substantial look, this band also delivers an outstanding, comfortable fit.

Beyond employing the sapphire crystal for high transparency, meticulous attention to detail is apparent throughout, including the delicate components of the intricate dial design, achieved with fine processing technology from Yamagata Casio.

This innovative, tough style delivers full-on practical 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.
