G-Shock • MTGB4000D-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-B4000 features an updated Dual Core Guard structure developed with the aid of artificial intelligence and an all-new frame design that combines carbon fiber and stainless steel. This unprecedented exterior achieves a new harmony of strength and beauty, pushing the frontiers of design.
This timepiece is a seamless collaboration between AI capabilities and human developers, creatively integrating materials, structure, and design into an organic whole of functional beauty. Base designs created by human designers were analyzed and simulated by AI to generate an optimized 3D prototype, which was then further refined by the human hand to achieve 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 are polished with separate hairline and mirror finishes for a sophisticated textural look.
The watch employs the Triple G Resist structure to withstand shock, centrifugal forces, and vibration. The case is also protected by the intricate dimensional form of the case back, which is created using metal injection molding (MIM), a method of metal processing in which fine metal powder is injected into molds.
The meticulous attention paid to every detail is apparent down to the sapphire crystal, which delivers high transparency, and the delicately crafted dial achieved with fine processing technology from Yamagata Casio.
This innovative, tough new 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.
