About GW-A1100 in Short. Technological G-Shock-s from the Gravitymaster line for pilots. The housing is equipped with triple air overload protection – protection against centrifugal force, vibration and shock. The watch module is surrounded by a special cushioning material alphaGel, which negates all the effects of any mechanical stress. The functions are controlled by the smart Smart Access crown, and the Tough Movement technology automatically adjusts the position of the hands if they are lost. Thanks to radio synchronization, you will always be aware of the current time, because the watch receives a radio signal from the towers several times a day. The GW-A1100 is powered by a solar cell that charges from daylight and does not require replacement. You can use a digital compass to navigate the terrain.

The most distinctive specs of GW-A1100 *Editorial
— 200-meter water resistance (good for swimming but not for deep diving)
— TRIPLE G RESIST (Shock resistant, Centrifugal force resistant, Vibration resistant)
— 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)
— Compass (measures and displays direction as one of 16 points)

Official Casio Description. With the ongoing success and popularity of our G-Aviation lineup, G-Shock has once again elevated watch performance and design with their latest introduction of the GWA1100-1A3. Triple G Resist construction enables it able to withstand the shock of gravitational dropping forces, centrifugal G-forces, and vibration. Smart Access enables intuitive, simple-to-master operation via an electronic crown and its direction and Sensors provide compass readings at a glance. Multi-Band 6 time calibration and Tough Solar Power provide accuracy and stable operation. Bold in design, resilient in structure and highly technical, the GWA1100-1A3 is as tough and visually stunning as it is electronically refined. Black analog watch and white and green accents on the dial.
