Casio Gravitymaster GWR-B3000-1AER Men's Watch • Triple G Resist • Solar-Powered with Bluetooth

The Casio G-SHOCK Gravitymaster GWR-B3000-1AER is a rugged pilot's watch from the exclusive Master of G line, designed for professionals who demand the highest standards of precision and durability. Inspired by the exhilarating speed of supersonic aircraft, it combines an innovative double-wall case construction with the advanced TOUGH MVT.2 movement, which automatically detects external disturbances such as strong shocks or magnetic fields and instantly corrects the hands. The case is crafted from bio-based carbon and stainless steel, while the strap is made from soft urethane with bio-based resin — a conscious contribution to reducing environmental impact.

The deep black dial with micro-fabricated surface textures minimises reflections and ensures clear legibility under all conditions. Sapphire crystal with anti-reflective coating protects the dial from scratches. Tough Solar technology combined with Multiband 6 radio time synchronisation and Bluetooth connectivity to the CASIO WATCHES app ensures consistently precise timekeeping, conveniently controlled via smartphone. The watch is water-resistant to 20 bar, meeting even the most extreme operational demands.
