Gulfmaster
GWNQ1000-1A
From G-Shock's Master of G line comes the GWNQ1000-1A Gulfmaster timepiece. The models in this range are designed to provide vital information about constantly changing ocean conditions for coast guard crews who respond to emergency situations on rough seas. In addition to being the first G-SHOCK analog models equipped with a depth sensor, these models also come equipped with a barometric pressure sensor that can be used to predict upcoming weather changes, a temperature sensor that detect the change of air and water temperature, and a digital compass that can be used to determine wind and tide directions. An auto level correction function detects the angle of the watch during digital compass readings and compensates accordingly, which helps to ensure correct readings while on a rocking boat. A dial at 5 o'clock is used to alert the wearer to sudden changes in barometric pressure, and acts as a Tide Graph to indicate high and low tide information. A dual-coil motor drives a retrograde dial hand to provide the wearer with instant feedback on the constantly changing natural environment. A new case reinforced with highly rigid carbon fiber adds a greater degree of toughness. Buttons are structured of metal pipes and triple O-rings for greater durability and water resistance. The shock resistant back cover and the urethane band create a comfortable fit to the wrist. Everything about these models is designed and engineered for maritime use.
