Casio announces a new Ocean Concept G-SHOCK timepiece which can predict weather changes, can measure Atmospheric Pressure/Altitude, and Temperature and loaded with many other functions such as world time, alarm functions, stop watch, tide level and Moonphase indications.
The GULFMASTER GWN-1000 is an ocean concept model inspired by the image of a strong man against rough seas. The new G-SHOCK boasts features useful for ocean activities — an atmospheric pressure sensor that can help predict changes in the weather, compass bearing to check the direction to a destination, and a tide graph that indicates the tide level.
Along with digital display of current atmospheric pressure values, second hand also indicates the change in pressure compared to the previously measured value. The hand points to a number engraved on the bezel, while the angle of the hand indicates the magnitude of the pressure change. A sudden spike or drop in pressure is indicated with an arrow in the inset dial, accompanied by an alarm signal. As a result, the wearer can get an accurate indication of atmospheric pressure change numerically, along with a more visual impression from the angle of the hand. This allows the wearer to take action when the weather is about to change.
The watch also indicates compass direction with the second hand pointing north, and the angle shown on the LCD. The wearer can use these functions to decide the direction to a destination across the open sea. In addition, the watch comes with a tide graph for pre-set locations so that the wearer can anticipate sea surface conditions at the destination for anchorage, etc. The watch boasts other multiple features useful for ocean activities such as water resistance to 200 meters and two separate LED lights for illuminating the dial and LCD.
The new GWN-1000 is also very easy to use. It is equipped with Smart Access, which enables its advanced functions to be operated intuitively. By pulling, turning, and pressing the crown, the world time and all the sensor functions can be accessed with ease. A single button calls up the sensor measurements, and different sounds indicate which sensor mode is in use. The watch also features a new band that is integrated into the case. Made from flexible soft urethane, the band also offers improved comfort.
While providing outstanding functions for ocean activities, the GWN-1000 is still eminently easy to use. It is a watch worthy of an ocean concept G-SHOCK. Going forward, Casio will aggressively promote G-SHOCK GULFMASTER series of G-SHOCK watches, named to capture the image of men tough enough to master the wild sea.
