The MT-G series combines resin and metal, the origins of G-SHOCK, to pursue innovative structural beauty.

The MTG-B4000D is a model with a Dual Core Guard structure that uses a carbon and stainless steel fusion frame developed by AI using accumulated impact resistance data.

Through co-creation between AI and humans, materials, structure, and form are organically combined to pursue original functional beauty.

In the AI-based development process, AI analyzes and simulates the designer's base proposal, optimizing it.
By repeating this process in a complementary manner, we were able to achieve a shape that is both functional and beautiful.

The carbon laminated frame is made by cutting a base material made of laminated sheets of carbon and glass fiber into a three-dimensional shape, forming a complex frame.

The stainless steel bezel has two parts, one inside and one outside.

Each part is polished with a hairline finish and a mirror finish for a beautiful finish.

The band is a layered composite band that combines stainless steel and carbon fiber reinforced resin.

The robustness of metal and the lightness of resin are combined to create a design with a sense of solidity, yet it is comfortable to wear.

It also features TRIPLE G RESIST, which is shock-resistant, centrifugal force-resistant, and vibration-resistant.

The back cover is three-dimensionally formed using MIM (metal injection molding),
a process in which powdered metal is injected to protect the case.

In addition, attention has been paid to every detail, including the use of highly transparent sapphire crystal and the intricately designed dial parts created using the fine processing technology of the Casio Yamagata factory.

In terms of functionality, the watch connects to the dedicated app "CASIO WATCHES" via Bluetooth? communication to obtain time information.

It also comes equipped with practical features such as Multiband 6, Tough Solar, and a high-brightness LED light.
