Casio G-Shock G-Steel GST-B1000BD-1AER

The metropolitan sophistication of G-STEEL draws inspiration from urban nights and city lights, expressed in a robust G-SHOCK that embodies refined engineering beauty: the GST-B1000BD model with black IP treatment. Changing its appearance from moment to moment as the light shifts on its surface, the logo-free bezel acquires a depth and brilliance that only the black IP finish can deliver. Stainless steel, molded in a minimalist style with black tones and aerodynamic shapes, creates an impression of refined elegance. The combination of satin and mirror-polished finishes gives a discreet yet solid presence to the stainless steel bracelet, which features a three-fold one-touch clasp ensuring an even more secure fit on the wrist. The bold and uncompromising design opts for an all-black aesthetic, with black IP treatment also applied to the smallest components, including the case back, side buttons, crown, clasp, and even the screws. The bezel design and brick pattern inherited from the very first G-SHOCK add a sporty touch to the minimalist look. The glass bonding and the use of a compact module result in a slimmer and lighter profile, without sacrificing the shock-resistant structure, thanks to the metal bezel that protects against impacts and the carbon-reinforced resin case that encloses the heart of the watch. All this converges in a rigorous synthesis of comfort, extreme durability, and everyday practicality. The all-black metal body shines naturally in a wide range of contexts: from the office to leisure, and even the outdoors. Elevating characteristic robustness and structural refinement to a whole new level, the GST-B1000BD is a versatile and ready-for-anything companion.
