Casio G-Shock G-Steel GST-B1000 Lineup Bluetooth© Tough Solar Bio-Based Black Resin Band Watch GSTB1000-2A GST-B1000-2A

A tough G-SHOCK dressed in refined structural beauty — the G-STEEL GST-B1000, now with a urethane band for a comfortable, lightweight fit. With sharply contoured lines, the metal bezel of the GST-B1000 delivers distinctive strength and sophistication for a sleek, urban look. The model with the black dial evokes fearless solidity, while the model with the blue dial, finished in vapor deposition, seems to change from glance to glance as light shifts across its surface. Choose your favorite look — either one is ready to take on the style and setting of whatever your day brings. Get the solid G-STEEL feel you love with the metal exterior and the easy everyday comfort and sporty style of a urethane band. The lighter, more comfortable, and totally natural fit offers long-wear comfort that your wrist will love, whether you’re working or playing hard. The bezel design, paired with the brick pattern inherited from the very first G-SHOCK, adds sporty style to a minimalist look. Adhesive glass bonding and a compact module result in a slimmer, lighter design without sacrificing the shock-resistant construction, thanks to the metal bezel that guards against impact and the carbon-reinforced resin case that protects the module. All of this comes together in an exacting combination of comfort and outstanding practicality, with Bluetooth®, Tough Solar charging, and more. Sophisticated metal and lightweight urethane blend seamlessly with a wide range of outfits, from business suits to weekend casual to outdoor adventures. Elevating tough construction, soft comfort, and modern elegance to a whole new level, the GST-B1000 is an all-around companion, ready for whatever comes your way.
