Casio Men's G-Shock G-Steel Watch Blue

$179.91

(1,105 reviews)

Introducing the latest variations to the G-STEEL lineup of down-sized G-SHOCK designs. This new model reduce the overall case size to approximately 90% 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.
