Casio G-SHOCK GXW GX-56 Series – Model GX56BBR-1
The GX56BBR-1 embodies the rugged toughness G-SHOCK is known for, blending bold black and striking red details into a powerful timepiece designed to withstand the harshest conditions. As part of the GX-56 Series — often called the “King of G-SHOCK” for its oversized, ultra-tough case — this model combines durability, functionality, and a daring design aesthetic.
Design Overview
The GX56BBR-1 features a commanding 55.5 mm case that dominates the wrist, enhanced with a high-saturation red LCD that pops against the matte black bezel and band. This vivid red not only improves visibility but also adds a dramatic edge to the design.
Engineered with Mud-Resistant and Shock-Resistant construction, this watch is built to endure dirt, mud, impact, and extreme environments. The Tough Solar power system ensures dependable, eco-friendly operation with minimal maintenance.
Activate the Super Illuminator LED backlight to illuminate the digital display for superior readability, day or night.
