Discover innovative form of great structural beauty, an MT-G timepiece born of an entirely new design concept combining the resin used in the first G-SHOCK models with metal materials. Welcome to a whole new level of sophisticated structural design.
With its even more advanced Dual-Core Guard structure, the MTG-B3000 protects the module in a carbon-reinforced resin case and encloses the exterior in metal components. Repeated pressing, cutting, and polishing builds the stainless steel case back upward into an intricate 3D form. The case back also serves as the lugs to secure the band and as the guards for crown and buttons, for a completely new structure. Using high-density mounting technology, we developed a new slimmer, multi-function module. All of these innovative designs and technologies created a much thinner watch, measuring just 12.1 mm from bezel to case back.
MT-G innovation extends even to the band. All-new one-touch exchange structure eliminates the need for special tools. Simply press the buttons located on either side of the lug to quickly and easily swap out the band.
High-transparency sapphire crystal paired with the delicate moulding and vapour deposition of Yamagata Casio’s nano-processing technology adds the final touch of sophistication and quality.
The MTG-B3000BD features a layered composite band made of hollow stainless steel segments encasing fine resin parts for a lighter weight band. Ion-plated metal components bring a touch of fresh color to the overall chic black design.
This innovative, tough new style delivers full-on functionality, as well. Download the CASIO WATCHES app to pair with your smartphone via Bluetooth®. With Multi-Band 6, Tough Solar charging system, and high-brightness LED light, this timepiece keeps you at peak performance, whatever your adventures may bring.
