Master in Marine Blue - Quad Sensors (Atmospheric Pressure, Temperature, Compass Bearing, and Water Depth Sensors) for Use in Ocean Environments

The GWN-Q1000 is the first G-SHOCK equipped with quad sensors to track constantly changing ocean conditions, designed to be useful for coast guard officers and others who are active at sea.

The GULFMASTER GWN-Q1000 is a seagoing concept model equipped with quad sensors to track ocean conditions, aiming to assist coast guard officers and others in security and rescue activities at sea. The atmospheric pressure sensor helps to predict suddenly changing weather conditions, the temperature sensor reads changes in air and water temperature, the compass bearing sensor helps detect wind and tidal direction, and the water depth sensor measures current depth under water. These sensors enable the user to assess changing ocean conditions in real time, in situations where they may be racing against time and the natural elements.

For ease of access, information from the five sensor modes (atmospheric pressure, altitude, temperature, compass bearing, and depth), as well as sudden atmospheric changes and a tide graph showing low and high tide information, are indicated on the inset dial at the 5 o’clock position. A dual coil motor enables a retrograde movement to display the information, for ease of recognition.

Optimized for use in ocean environments, the watch case is made from carbon fiber materials for superior rigidity. The button casings use metal pipes for high durability and enhanced water resistance. Furthermore, the shock absorbent back cover and watchband are made of soft urethane for better comfort on the wrist.

The MASTER Of G Series is proud to announce new Master in Marine Blue models.

The beauty of the vast, unexplored oceans is offset by an environment that is so harsh it deters regular divers. The reverence felt by the technical divers and their support crew who explore the caves, caverns, and wrecks in this tough environment is embodied by beautiful emerald green and blue colors.

The quad-sensor GWN-Q1000MB starts with basic black brand coloring, which is accented by the emerald blue of the second hand and retrograde hand. An ion-plated (IP) bezel adds a touch that recalls the sparkling ocean surface.
