From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, comes the GSTS300G-1A9 G-STEEL model. This new model has an overall case size that is approximately 90% the scale of previous models, while incorporating existing layer guard structure and functions. This dramatic reduction in the module size makes it possible to make the case thinner and more compact. The GST-S300G model has a resin bezel and urethane band. A hefty urethane band provides improved fit, which lightens the load to the wrist during long-term wear. Full-auto LED illumination provides outstanding readability, even in the dark.
