Casio GST-B1000BD-1AER Men's Watch G-SHOCK G-STEEL Black • Tough Solar & Bluetooth • Shock-Resistant 20 Bar

The Casio GST-B1000BD-1AER is a striking men's watch from the G-SHOCK G-STEEL series, combining urban elegance with uncompromising durability. The black ion-plated stainless steel case features a streamlined silhouette that impresses with its blend of brushed and mirror-polished surfaces. The logo-free bezel shimmers in the light, lending the watch a unique depth — a result of the black ion-plating treatment. The solid stainless steel bracelet is secured by an elegant triple-fold clasp with a one-touch release mechanism.

The case is constructed from bio-based carbon and stainless steel with a Carbon Core Guard structure that protects the module from shocks without compromising the slim profile. The GST-B1000BD-1AER is water-resistant to 20 bar and fully solar-powered thanks to Tough Solar technology. Via Bluetooth and the CASIO WATCHES App, the watch connects effortlessly to your smartphone for automatic time synchronisation. Neobrite luminous material ensures excellent legibility in low-light conditions.
