"G-SHOCK", a shock-resistant watch that builds a new concept of toughness in watches
The MT-G series pursues innovative structural beauty by fusing metal materials and resin materials, the origin of G-SHOCK, with a unique design concept.
The MTG-B3000 has further evolved the "dual core guard structure"
that protects the module with a carbon reinforced resin case and covers the outside with metal parts.
The stainless steel back cover is molded into a complex three-dimensional shape through multiple processes of pressing, cutting, and polishing.
We took on the challenge of a completely new structure and design in which the functions of the lug that secures the band, the crown guard, and the button guard are provided on the back cover, and we have also achieved a smaller and thinner size.
In addition, by developing a thin multi-function module using high-density mounting technology, the distance from the back cover to the bezel is 12.1mm, which is significantly thinner than the existing MT-G model.
In addition, we have newly developed a one-push replacement band structure that allows you to easily change the band without tools, and you can easily change the band by pressing the button on the lug part from both sides.
MTG-B3000D adopts a lightweight layered composite band with stainless steel and fine resin.
After applying a black IP coating to the stainless steel bezel, it is finished with a hairline finish to expose the stainless steel only on the top surface.
Highly transparent sapphire glass is used, and the dial is finished with a high quality finish by applying delicate molding using the fine processing technology of the Casio Yamagata factory and vapor deposition processing.
In terms of functionality, it connects to the dedicated app "CASIO WATCHES"
via Bluetooth® communication to acquire time information.
Equipped with multiband 6, tough solar, and high-brightness LED light, it also has practical functions.
