Here comes a new G-STEEL model that feature Carbon Core Guard structures. The bezels of GST-B200X are made of lightweight yet very rigid carbon material for the ultimate in shock resistance. Highly scratch resistant clear sapphire glass is used for the crystal to enhance readability and appearance, and to provide both toughness and good looks. In addition, hefty urethane bands feature a sporty outer surface pattern that integrates well with the textured pattern of the bezels.
