From the seafaring MASTER OF G GULFMASTER series come a new model colored in Navy blue with gold color accents and with module no. 5371, and packed with powerful features like Triple Sensor Version 3 and Smart Access. In addition to barometric pressure and altitude, bearing, and temperature sensors, this watch also features Tide Graph and Moon Age capabilities to provide you with detailed information about changes in the environment around you. Sudden change in barometric pressure is alerted by a dial hand, digital display indicator, and audible alarm. Even in the dark, display information is kept easy to read by a dial light at 6 o’clock in addition to the digital display back light.This model is designed to resemble oceangoing vessel instrumentation, and large light and sensor buttons are provided for easy access to critical functions when they are required.Unmatched function, great design, and G-SHOCK toughness all add up to give this watch what it takes to support maritime activities.
