From G-SHOCK, the brand that is constantly pushing the envelope of timekeeping toughness, come new G-STEEL model design variations with "layer guard structure" for outstanding shock resistance. The bands of these models combine different materials for outstanding strength and wear resistance. The core of the band is resin, the outer surface is CORDURA® fabric, which is stronger than nylon, and the inner surface is Tough Leather, which is used for heavy-duty work wear. The GST-S130BC Series models come with a urethane bezel that is marked with a pattern that recalls the grip of an instrument or tool. The GSTS130C and GST-S330C models feature a metal bezel that looks sharp and solid.
