Update: Early GWN-Q1000 models were known to have problems with the analog hands becoming misaligned and needing repair. Casio corrected the problem in later models, but the GWN-Q1000 series was recently discontinued. If you are looking to buy this model, consider the GWN-Q1000A-2AJF, which was the most recent active model in Japan before the series was discontinued.
The most surprising Casio news out of Baselworld 2016 is the announcement of the G-Shock Gulfmaster GWN-Q1000, an all-new ocean concept Gulfmaster model and the first G-Shock to feature the Quad Sensor. The Quad Sensor includes the altimeter-barometer, compass (with automatic horizontal compensation or “level correction”), and thermometer of the Triple Sensor, plus a depth gauge to measure water depth like the upcoming Frogman GWF-D1000. The GWN-Q1000 is a significant upgrade to the Gulfmaster GWN-1000 that will prove its seaworthiness to the most demanding maritime users.
Update: The first two GWN-Q1000 models are the black and blue GWN-Q1000-1AJF and the white and blue GWN-Q1000-7AJF with a list price of ¥100,000 JPY each and an August 2016 release in Japan.
Update 2: Casio announced a September 2016 Asia release for the GWN-Q1000-1A and GWN-Q1000-7A. Casio America announced the GWNQ1000-1A for a September release with a list price of $850.
The environmental sensors are designed to track changing ocean conditions by coast guard personnel and others who are active on the sea. The barometer tracks changes in atmospheric pressure to predict sudden weather changes. The thermometer tracks changes in air and water temperature. The compass helps to determine the direction of the wind and tides. The depth meter measures the current depth when underwater.
The GWN-Q1000 also has a tide graph and moon age data. It is the first Gulfmaster model with sunrise/sunset data and a sapphire crystal. The watch has a resin case with a carbon fiber reinforcement. The back cover and band are made of soft urethane for maximum comfort on the wrist. The markers and hands have a phosphorescent treatment for visibility in the dark.
The Gulfmaster GWN-Q1000 exterior design is similar to the GWN-1000 with some unique changes. The LCD subdisplay is now on the upper half of the face and the tide graph and barometer indicators are at the 5 o’clock position and also include a sensor mode indicator. The side buttons look more like the Frogman rather than the circular buttons of the GWN-1000. Like the GWN-1000 it has numbers on the bezel to display changes in altitude and atmospheric pressure.
Other key features include shock resistance, 200-meter water resistance, Tough Solar power system, Multi-Band 6 radio wave time-syncing, world time (48 cities + UTC), 1/100 second stopwatch (24 hours), countdown timer (60 minutes), 5 daily alarms, hourly time signal, manual sensor memory function with time stamp function, and full auto double LED light with afterglow (1.5 or 3 seconds).
The GWN-Q1000 measures 48.0 × 57.3 × 17.0 mm and weighs 113 grams.
