Casio G-Shock G-STEEL

The Casio GST-B1000D-3AER is a men's watch from the G-STEEL collection within the legendary G-Shock family. It combines robust Tough Solar technology with Bluetooth connectivity and a minimalist design in green. The case crafted from bio-based carbon and stainless steel, paired with a solid stainless steel bracelet featuring a one-push triple-fold clasp, gives this watch a timeless, refined look that performs equally well in business meetings and outdoor adventures.

The GST-B1000D-3AER is equipped with the Carbon Core Guard structure, which reliably protects the module against shocks. The Bluetooth connection to the CASIO WATCHES app enables automatic time synchronisation, world time display, phone finder functionality and straightforward watch configuration via smartphone. Thanks to Tough Solar, the watch is charged by light, ensuring long power autonomy without battery replacement. The adhesive-bonded mineral glass crystal contributes to the slim, lightweight profile without compromising shock resistance.

Key Features of the Casio GST-B1000D-3AER Watch

  • Tough Solar with Bluetooth: Solar charging combined with smartphone connectivity for automatic time setting and easy operation via app.
  • 20 Bar Water Resistance & Carbon Core Guard: Exceptional shock and water resistance thanks to a robust construction of bio-based carbon and stainless steel.
  • Elegant G-STEEL Design: Solid stainless steel bracelet with three different surface finishes and a logo-free bezel for a modern, minimalist look.
