Casio G-Shock G-Steel GST-B200 Lineup Carbon Core Guard Structure Watch GSTB200X-1A2 GST-B200X-1A2

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.

The case is made of fine resin that incorporates carbon fiber for light weight along with rigidity that is superior to that of resin alone.
