MASTER OF G GULFMASTER This is a twin sensor model of the G-SHOCK “Gulf Master” series, which is intended for use at sea, which is one of the harshest natural environments on earth. In addition to a 60-second continuous measurement function that allows you to check the course and a temperature measurement function that is important in the event of an unforeseen situation, it is equipped with a tide graph and moon data to support a wide range of activities at sea. The band is firmly connected from the entire surface of the case, and the curved shape improves the fit to the arm. It boasts a comfortable fit and high practicality even for a long time. The face design is based on the equipment and instruments of the ship. Aluminum is used for the bezel, which is color-coded into two colors, to reduce weight. In addition, by applying blue everywhere, the design is full of marine taste.
