Casio G-Shock MT-G Diffuse Nebula MTG-B3000DN-1A

The design of the new MTG-B3000DN is inspired by the beauty of the nebulae twinkling in the galaxy. This brilliant light is reproduced through the gradations of blue and purple on the bezel and dial, made possible by a vapor deposition process. The strap is made of soft black urethane mixed with aluminum material in four different colors. The stainless steel components, finished with blue and purple IP, represent the twinkling stars. Thanks to its Dual Core Guard protection structure, the MTG-B3000 model protects the module in a carbon fiber-reinforced resin case, while the external parts have metal components. Repeated pressing, cutting, and polishing builds the stainless steel case upwards, giving it an intricate 3D shape. In this structure, the caseback also serves as the strap attachment lugs, protecting the crown and buttons. This sophisticated design helps make the watch more compact and slim. Using cutting-edge assembly technology, we've developed a new, slimmer multifunction module, resulting in a watch measuring just 12.1 mm from case back to bezel. This innovative and durable new style offers comprehensive functionality. By downloading the CASIO WATCHES app, it can be paired with your smartphone via Bluetooth®. Thanks to Multiband 6, the Tough Solar power system, and the high-brightness LED, these watches ensure optimal performance on any occasion. The rainbow-effect color of the ion plating varies from watch to watch.
