Projecting toughness and vibrance with high-impact rescue yellow

The worldview of professionals engaging in rescue missions is expressed with a vivid yellow hue conveying danger awareness. Prominently featuring this eye-catching colour, this trio of timepieces builds on GRAVITYMASTER, MUDMAN, and RANGEMAN designs from the MASTER OF G line of watches which demonstrate their true potential in extreme conditions. Standing out strikingly against solid, powerful black, the vibrant colour projects the characteristic toughness of G-SHOCK.

Eye-catching contrast: Vibrant rescue yellow

Vivid yellow is featured prominently in the watch designs as a key colour. Employed on equipment and vehicles used by rescue teams, the striking hue serves as a caution colour that powerfully projects its presence amid adverse weather conditions, poor visibility, and other demanding environments. Rescue yellow accents on parts including the band and bezel’s top create a high-impact look. Black and grey IP gives enhanced textural appeal to metal components to realise toughness-driven design fitting for professional gear.

Duplex LCD display - MUDMAN GW-9500MRY

Built with a shock-, dust-, and mud-resistant structure, the MUDMAN GW-9500MRY is equipped with Triple Sensor, which measures compass bearing, altitude/barometric pressure, and temperature. The digital compass display employs a duplex LCD for greater practical utility.
