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 buttons

located on both sides of the lugs to quickly and easily swap out the

band.

High-transparency sapphire crystal paired with the delicate molding and

vapor 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.
