Based on the MTG-B2000 which is a fusion of a monocoque case made of carbon fiber reinforced resin and a metal material this model uses carbon material for the bezel parts to reduce weight. The carbon bezel is formed by laminating a carbon fiber sheet and a glass fiber sheet making a plate-shaped base material by heat pressing and cutting from there. For MTG-B2000YBD the bezel frame on the side of the watch has been changed to carbon material. The weight is significantly reduced compared to stainless steel and the bezel frame is about 77% lighter. The carbon sheet on the top layer of the bezel frame is layered and strengthened so that it wraps around the side at 3 o'clock 6 o'clock 9 o'clock and 12 o'clock and the lug part is strengthened by wrapping the carbon sheet in a cylindrical shape. increase. The glass fiber layer is accented with red which is the G-SHOCK brand color. The MTG-B2000XD has a fresh design with the top bezel carbonized and the first green color used for the laminated glass fiber layer. In addition the texture of the entire product is also high such as the adoption of highly transparent sapphire glass and the dial with delicate engraving by the microfabrication technology of the Casio Yamagata Factory. In terms of functionality the Bluetooth communication function connects to the dedicated app G-SHOCK Connected to acquire time information. Equipped with multi-band 6 tough solar and high-brightness LED lights it has practical functions.Module No: 5636Triple G resist (impact-resistant structure centrifugal gravity-resistant performance vibration-resistant structure)Tough solar (solar charging system)20 ATM water resistant functionRadio wave reception function: Automatic reception (up to 6 times / day) (Chinese radio waves up to 5 times / day) / manual reception
