Features
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.
