G-SHOCK is a watch that pursues toughness. It may have a strong impression of being casual, but the "MT-G" is a collection for adults that goes beyond the concepts of casual or too sporty. Its unique structure, which combines resin and metal, gives it both luxury and durability. This time, we will thoroughly explain the appeal of the "MT-G."
What is “MT-G”?
The MT-G collection combines the shock resistance of G-SHOCK with the luxury of metal. It was launched in 1999 based on the concept of combining different materials. Until then, G-SHOCKs had emphasized shock resistance and primarily featured plastic cases. However, the MT-G overturned this concept, adopting a hybrid structure that combined the robustness of metal with the flexibility of resin, creating a new appeal.
The greatest feature of this series is that it maintains the toughness that is characteristic of G-SHOCK while adding a sense of weight and luxury. By utilizing the characteristics of different materials, it achieves a sporty yet sophisticated design.

Another attractive feature of the MT-G lineup is that all of them feature analog displays. When you think of G-SHOCK, you might imagine a digital display. However, the MT-G's mechanical analog design makes it a style that mature men can wear comfortably. The MT-G's combination of analog hand movement and the solid feel of metal gives it a sophisticated look, making it suitable for business settings while still making a statement on the wrist.
The latest MT-G series, which has also achieved technological advancements, employs a carbon core guard structure to achieve even lighter weight and greater strength. The frame combines the flexibility of resin with the strength of carbon to firmly support the metal exterior and protect the movement from impacts. Furthermore, some models are equipped with advanced features such as Bluetooth smartphone connectivity and GPS hybrid radio-controlled solar, making them not only aesthetically pleasing but also practical.
It is also worth noting that the MT-G pursues high design quality, with a polished metal case, a three-dimensional dial, and a wide range of colors. The appeal of the MT-G is that it is a casual watch that also has a luxurious feel and can be used in a variety of situations.

More than 20 years have passed since its birth, and the MT-G has evolved significantly from the original model. However, the concept of "combining resin and metal" remains unchanged, and it continues to exude a unique presence among G-SHOCK models.
What types of MT-G are there?
Among the G-SHOCK models, the MT-G series boasts exceptionally sophisticated design and robust construction. The ever-evolving lineup includes the MTG-B1000, MTG-B2000, and MTG-B3000, each with its own unique features to meet a wide range of needs. This article will take a closer look at the main MT-G models.
MTG-B1000シリーズ

The MTG-B1000 series is a representative MT-G model. Featuring a robust design and chic finish, it offers G-SHOCK's shock-resistant construction while pursuing a superior fit and functionality. While inheriting the G-SHOCK DNA, its unique construction, combining resin and metal, gives it an unprecedented presence.
The Core Guard structure, the key to the shock-resistant design, encases the module in a resin inner case and securely protects it with a metal exterior. This allows for external shock absorption while maintaining a robust design that takes advantage of the solid feel of the metal. In addition, Triple G Resist makes the structure not only shock-resistant, but also resistant to centrifugal force and vibration, ensuring high performance even in harsh environments.
The bracelet uses a layered composite band with fine resin parts embedded behind the metal, ensuring strength while also being lightweight and comfortable to wear. Despite its heavy appearance, it is designed to be comfortable to wear even for long periods of time. Furthermore, it is water resistant to 20 bar, making it safe to use in a wide range of environments, from outdoor activities to business settings.
It also boasts excellent functionality, featuring a "Tough Solar" solar charging system that allows it to be charged using sunlight or indoor light. It eliminates the need for periodic battery replacement and provides stable operation over a long period of time. Another major attraction is its compatibility with Multiband 6, which receives standard radio waves from six stations around the world, ensuring accurate timekeeping. It also features Bluetooth smartphone connectivity, allowing you to easily set the time and perform various settings via the dedicated app.
MTG-B2000シリーズ

The MTG-B2000 series combines the traditional Metal Core Guard structure with a new Carbon Core Guard structure for a Dual Core Guard structure, achieving both strength and lightness. By combining a metal frame with a monocoque case made of carbon fiber reinforced resin, the watch achieves high strength, airtightness, and light weight, providing a robust yet comfortable fit.
The bezel frame is made by laminating and carving out 235 sheets of carbon and glass fiber, achieving a weight reduction of approximately 77% compared to stainless steel models. In particular, the MTG-B2000XD features a distinctive carbon pattern on the top of the bezel and a newly developed green and black laminated pattern on the sides, adding a sophisticated touch to the sporty impression.
The bracelet uses a "layer composite band" that combines metal and fine resin parts. This provides a lightweight and comfortable fit while retaining the luxury of metal. Metal powder injection molding (MIM) has been used to hollow out the metal parts, further reducing the weight. The double slide lever structure makes it easy to put on and take off the band, improving convenience.
Even the smallest details are meticulously finished, with the sloped surfaces of the metal parts being Zaratsu polished to create a highly smooth mirror surface, resulting in a luxurious finish that is typical of MT-G.
It boasts excellent specifications in terms of functionality, and can be connected to a smartphone via Bluetooth for time adjustment and alarm setting. Equipped with Tough Solar and Multiband 6, it keeps accurate time. It also features a Super Illuminator that ensures visibility even in dark places, making it extremely practical.
MTG-B3000シリーズ

The MTG-B3000 series further strengthens the existing Dual Core Guard structure, achieving a slimmer and lighter body. This innovative series maintains its solid design while improving comfort and practicality.
Its greatest feature is its newly designed slim structure. The carbon fiber-reinforced resin case protects the module, and the exterior is covered with metal parts, maintaining shock resistance while keeping the case thickness to 12.1mm. Compared to the previous MTG-B1000, the module is 1.45mm thinner, while maintaining the robustness of G-SHOCK. Furthermore, the complex, three-dimensional back cover secures the band and protects the buttons, achieving greater rigidity and a more refined design. The beauty of the metal exterior is also maintained, with the stainless steel back cover achieved through processes such as pressing, cutting, and polishing, resulting in a three-dimensional and complex structure. Designed to interlock with the top bezel and secured with specially shaped screws, it creates a sense of solidity despite its slim design. The surface is Zaratsu polished, creating a beautiful luster and a sharp, striking design.
In terms of functionality, the watch is equipped with a solar-powered radio wave system that combines Bluetooth smartphone connectivity with time standard radio wave reception. It automatically adjusts the time to keep it accurate, so you don't have to worry about time discrepancies anywhere in the world. The sapphire crystal glass is coated with an anti-reflective coating on the inside for excellent visibility. Combined with the Super Illuminator, it's suitable for any environment.
The band features a one-push replacement system, allowing you to easily change the band without any special tools. You can choose from a layered composite band made of metal and fine resin, or a lightweight soft urethane band, allowing you to customize the watch to suit your needs. Furthermore, the watch features a black base with red and green accents, thanks to the IP coating, creating a unique design that stands out.
The MTG-B3000 series combines the toughness of G-SHOCK with a slim, sophisticated design and high functionality, making it the ideal model for watch enthusiasts seeking a comfortable fit and the solid feel of metal.
