MTG-B4000 Series Watch MTG-B4000B-1A2

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.
