Casio G-Shock GWN-1000 Watches

Functional G-Shock watch for sailors and boating enthusiasts. The design of the dial with its window in the form of a compass needle and round hour markers, which will be readable even in conditions of poor visibility, hint at a marine orientation. The metal parts of the case received a special anti-corrosion surface treatment – the watch is not afraid of prolonged exposure to water. There is a full range of functions for professional maritime affairs – a barometer that can predict weather by atmospheric pressure, an altimeter, a thermometer and a digital compass. The tide sensor will keep you informed of the current water level anywhere in the world. With the Smart Access crown, you can quickly access all the features of the GWN-1000. Time is automatically adjusted by radio waves, and the solar battery will allow you to forget about replacing it for a very long time.

The most distinctive specs of GWN-1000 *Editorial
— 200-meter water resistance (good for swimming but not for deep diving)
— Tough Solar (CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power)
— Radio-controlled Watch; Multi band 6 (additional way for time sync. This watch receives time calibration radio signals that keep the displayed time accurate)
— Smart Access (the system for analogue movements achieves multi-functionality and easy operability simultaneously through a combination of multiple motors and an electronic crown)
— Tough Movement (A CASIO-original thin analog movement made possible by hybrid mounting protects against damage and enables auto home position correction that helps keep you on time all the time)
— Digital compass (measures and displays direction as one of 16 points)
— Thermometer (can measure and display the outside temperature in a range from -10 C to 60 C)
— Barometer (measures the air pressures and displays tendencies in the weather)
— Altimeter (The electronic mechanism “estimates” the altitude based on the air pressure)
— Moon data (moon age of the specific date)
— Tide graph (tide level for specific date and time)

Official Marketing Focus from Casio

Introducing GULFMASTER, the new G-SHOCK Series that’s designed and engineered with the maritime adventurer in mind.
GULFMASTER includes the first G-SHOCK models to incorporate both Triple Sensor Version 3 and Smart Access in the same watch. In addition to barometric pressure, altitude, bearing, and temperature readings, these new models also feature Tide Graph and Moon Age capabilities to help keep you in close touch with your natural environment. Sudden extreme changes in barometric pressure are alerted using a dial hand, LCD display, and alarm. Double LED lighting illuminates the LCD, and also adds a face light at 6 o’clock to keep information bright and easy to read even in total darkness.
