G-Shock MT-G Series MTGB2000D-1A

These new lightweight metal models, with newly advanced shock-resistant structures, are the latest additions to the MT-G lineup that packs the latest that technology has to offer into shock-resistant designs that combine metal and resin materials.
A Carbon Core Guard structure combines with the Metal Core Card structure to create a new Dual Core Guard structure, which houses a module protected by an integrated carbon monocoque case and exterior metal parts. The New Layered Composite Bands of these models use hollow metal segments that encase fine resin parts, providing the elegant feel of metal along with weight that is 15% less than that of previous models. The metal frames have a new type of slide lever mechanism that makes band replacement quicker and simpler, and metal is also used for the outer case sides.
The bezel is a piece that is separate from the metal frame, which enables greater coloring versatility. The elegantly attractive mirror finish of the exterior metal parts gives these watches their distinctive look. The elegance of these models is further enhanced by high-transparency sapphire crystals, as well as hour markers and inset dials that are precision engraved at the CASIO Yamagata Factory.
