【MTG-B1000XBD-1AJF】 This MT-G model, featuring advanced technology in a shock-resistant body that fuses metal and resin, is clad in carbon fiber. It employs a "Core Guard Structure" that integrates the lugs and pipes connecting the band to protect the module. The center case uses carbon fiber reinforced resin, achieving both lightness and shock resistance. This is the first mid-size model in the MT-G series, and the composite band enhances wearability, while the case and band connection features a vibration-resistant structure. The bezel uses carbon fiber, known for its lightness and high rigidity. Accent colors are placed in the layered sections of the carbon bezel, and the edges of the metal parts are mirror-polished, while each surface is hairline-finished for aesthetic appeal. The use of sapphire glass and delicate engraving, achieved through the processing technology of Casio's Yamagata factory, further enhances the texture. Bluetooth communication allows connection to the dedicated "CASIO WATCHES" app to acquire time information. It also features practical functions such as a high-brightness LED light and world time, which are stably powered by "Tough Solar."
