About the Watch in short. 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.

*some images are about G-Shock 5000/5600 cases, but the technology, approaches, concepts and philosophy remains the same for the whole G-Shock Model Range

Solar Power. None-Stop – A solar panel converts even weak illumination from fluorescent lighting into electric power. A rechargeable battery with a large power storage capacity supports stable operation of various functions with high electricity consumption. You never have to worry about the battery running down because it’s a solar battery. Casio watches with solar technology, receive thermal and electrical energy that recharges the watch batteries through solar panels on the face of the watch.

MultiBand 6. Terrestrial radio wave reception from 6 transmission stations worldwide. Automatic time correction available in Japan, North America, UK, Europe and China.
— Reception is possible even when surrounded by buildings.
— Signals are received during the night to keep the displayed time exact. — Reception is possible with less than normal power consumption.

Smart Access. This analog control system combines Multi Mission Drive, which assigns multiple functions to individual hands, with an electronic crown switch. World Time city selection is conducted with simple crown operation, providing quick access to the times in the world’s major cities.

Multi-motor construction. Smooth switching of the various displays is achieved by a drive mechanism including an optimized number of motors. Electronic Crown Switch. Smart Access makes it easy to operate CASIO’s multi-function watches. Simply pulling out and rotating the crown provides intuitive control over world time city selection and various other functions.

Tough Movement. Tough Solar, Multiband 6, Auto Hand Home Position Correction and Hybrid Mount Construction. These four technologies combine in a radio-controlled, solar-powered analogue movement that elevates the reliability of solar-powered, radio-controlled analog watches to new heights.

Official Casio Description. 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.
