Casio G-Shock MTG-B3000D-1A Black Stainless Steel Band Men Watch

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 build 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 the bezel to the case back.

The MTG-B3000D features an even lighter layered composite band made of stainless steel and fine resin. Its stainless steel bezel is ion-plated in black, then treated with a hairline finish to expose the stainless steel below the convex surfaces only. These meticulous details come together to offer an intricate and sophisticated design.
