Casio G-Shock GRAVITY MASTER Tough Solar Men's Watch | GR-B300-8A2DR

Introducing the Casio G-Shock GR-B300-8A2DR Gravity Master Men's Watch, a rugged timepiece from the Master of G Series designed with aviation professionals in mind. This Tough Solar-powered watch offers extreme durability, featuring a Bio-based carbon and resin case combined with a bio-based resin band, making it eco-friendly and resilient.

The watch weighs only 71 grams and boasts a Carbon Core Guard structure, delivering superior shock resistance, rigidity, and corrosion resistance, akin to the materials used in aircraft fuselages. With a 200-meter water resistance, it's built to endure harsh environments both on land and at sea.

For aviation enthusiasts and frequent travelers, the GR-B300 features Bluetooth connectivity, which allows for automatic time adjustments when paired with a smartphone. Its dual-time display and flight log memory function enable tracking of time in two zones, offering a seamless transition between home and local times.

The watch’s large, dimensional index markers and metal bezel highlight the bold, professional design, enhancing readability even in low-light conditions, which is critical for pilots. At the 9 o’clock position, a rotary disc indicator powered by a dual-coil motor displays alarm on/off, stopwatch, and battery level information.

Its bold black and white color scheme with strategic color accents reflects the look of a cockpit instrument panel, adding both aesthetic and functional value. This aviation-inspired timepiece is not only practical but also environmentally conscious, incorporating bio-based resin to reduce its environmental footprint.

The Casio G-Shock GR-B300-8A2DR is a perfect blend of advanced technology, durability, and eco-friendly design, ideal for professionals and adventurers alike. Available at Watch Zone
