G-Shock MTG-B3000BDE-1A Two Interchangeable Bands

Discover a whole new level of sophisticated design. Indulge your senses with the innovative form of superior structural beauty — an MT-G timepiece that combines original G-SHOCK resin with metal for an entirely new design concept. Accented in gold hues, the MTG-B3000BDE comes with two interchangeable bands: a lighter weight, layered-composite band made of stainless steel and fine resin, and a soft urethane band with band loop and buckle ion-plated in gold. The all-new one-touch exchange structure eliminates the need for special tools. Simply press the buttons located on the sides of the lugs to quickly and easily swap out the band. 
With its even more advanced Dual Core Guard structure, MTG-B3000 watches protect the module in a carbon-reinforced resin case and enclose 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. 
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.
