With the ongoing success and popularity of our G-Aviation lineup, G-Shock has once again elevated watch performance and design with their latest introduction of the GWA1100-1A3. Triple G Resist construction enables it able to withstand the shock of gravitational dropping forces, centrifugal G-forces, and vibration. Smart Access enables intuitive, simple-to-master operation via an electronic crown and its direction and Sensors provide compass readings at a glance. Multi-Band 6 time calibration and Tough Solar Power provide accuracy and stable operation. Bold in design, resilient in structure and highly technical, the GWA1100-1A3 is as tough and visually stunning as it is electronically refined. Black analog watch and white and green accents on the dial.
