Casio G-Shock Gravitymaster GR-B300-8A2 Black Dial 55mm Bio-Based Resin Men's Watch

The Casio G-Shock GR-B300-8A2 is a professional-grade aviation timepiece from the "Master of G" Air series, released in May 2024. Its design is inspired by the organic, flowing lines of next-generation aircraft and fighter jets, featuring a seamless exterior that connects the case to the band for a cutting-edge look. This model utilizes a Carbon Core Guard structure with a carbon fiber-reinforced resin case, a material also found in aircraft fuselages, providing extreme shock resistance, rigidity, and corrosion resistance.The watch is equipped with a high-contrast 3D face design for intuitive reading, featuring a triple-layer dial with a rotary disc indicator at the 9 o'clock position. This indicator is driven by a dual-coil motor to smoothly display battery levels, alarm status, and stopwatch modes. For pilots and frequent travelers, it offers Dual Time to display two time zones simultaneously and a specialized Flight Log function to record coordinates and routes via the CASIO WATCHES app. True to G-Shock’s sustainability efforts, the case, bezel, and band are crafted from bio-based resin.
