Introducing RANGEMAN, the latest addition to the Master of G series of tough and rugged timepieces that are designed and engineered to stand up to the most grueling conditions imaginable. RANGEMAN is Triple Sensor equipped, which makes it capable of keeping altitude, barometric pressure, temperature, and direction readings at your fingertips. Cylindrical buttons provide outstanding operation and improved resistance to impact. The frequently used sensor button (center right) has a metal cover that protects it against lateral impact and keeps foreign matter out.
