G-Shock MT-G Connected MTG-B4000B-1A2

By the future, for the future The G-Shock MTGB4000 features an updated Dual Core Guard structure developed by Casio designers with the aid of artificial intelligence and an all-new frame that combines carbon fiber and stainless steel. This unprecedented exterior achieves a new harmony of strength and beauty, pushing the frontiers of watch design.  The intricate, dimensional form of the frame is cut out from a base material of laminated carbon and glass fiber sheets, creating a beautifully layered pattern. The stainless-steel components of the bezel are polished with separate hairline and mirror finishes for a sophisticated textural look.  The watch employs the Triple G Resist structure to withstand shock, centrifugal forces, and vibration. The case is also protected by the intricate dimensional form of the case back, which is created using metal injection molding (MIM), a method of metal processing in which fine metal powder is injected into molds. The meticulous attention paid to every detail is apparent down to the sapphire crystal, which delivers high transparency, and the delicately crafted dial achieved with fine processing technology from Yamagata Casio.  This G-Shock is characterized by its newly developed blue-gray ion-plating on the bezel and other stainless-steel components. This innovative, tough new style delivers full-on functionality, as well. Download the CASIO WATCHES app to pair with your smartphone via Bluetooth®.
