G-Shock G-Steel GST-S100 series Mens Watch GSTS100G-1A.
From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, comes the G-STEEL GST-S100G-1A, a watch series with a new "layer guard structure". Different materials are used for the bezel to create a two-layer structure that adds a new dimension of shock resistance.
For models that use stainless steel in the upper part, shock absorbing resin is employed in the lower part. If resin is used in the upper part, fine resin is used in the lower part to cushion against impact from the upper part. This also has made it possible create a wide range of different designs.
Tough construction meets stylish design with metal bezel ion-plated in gold set against a black base. This sophisticated fashion statement with a luxury feel and cool look takes you where you want to go. G-Shock GSTS100G-1A.
