Gwn1000e Gulfmaster White/navy
In 1983 Kikuo Ibe, Casio’s research and development engineer set out to design a watch that could survive a 10m drop after his first ever watch, a gift from his parents on graduation day, broke from a fall. G-Shocks are world famous for quality and extreme toughness. Worn by military through to action sports athletes, every man should have at least one G-Shock in his stylin’ artillery.
From the seafaring GULFMASTER series come a new model colored in Navy blue with gold color accents, and packed with powerful features like Triple Sensor Version 3 and Smart Access.
In addition to barometric pressure and altitude, bearing, and temperature sensors, this watch also features Tide Graph and Moon Age capabilities to provide you with detailed information about changes in the environment around you. Sudden change in barometric pressure is alerted by a dial hand, digital display indicator, and audible alarm. Even in the dark, display information is kept easy to read by a dial light at 6 o’clock in addition to the digital display back light.
This model is designed to resemble oceangoing vessel instrumentation, and large light and sensor buttons are provided for easy access to critical functions when they are required.
Unmatched function, great design, and G-SHOCK toughness all add up to give this watch what it takes to support maritime activities.
An electronic crown switch and the use of multiple motors combine to enable conflict-free simultaneous operation of multiple functions, and smooth switching between functions.
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.
Tough Solar ensures stable operation even when using power-hungry functions.
