Casio G-Shock G-Steel GST-B1000-2AER

The G-STEEL GST-B1000 combines the strength of metal with the lightness and comfort of a urethane band for a modern, versatile look. The sharp metal bezel gives it urban and sophisticated character, while the carbon-reinforced resin case protects the module from impacts.

The compact and slim design maintains the iconic G-SHOCK toughness, with the distinctive brick pattern inspired by the first G-SHOCK. The black dial expresses a decisive character, while the blue version with a vapor deposition finish creates refined reflections in the light.

Completing the features are Bluetooth®, Tough Solar, and a comfortable fit designed for daily use, from professional settings to leisure.
