Casio G-Shock Gravitymaster GW-A1100-1A3DR
Quick Operation Guide
Introducing a new color for GRAVITYMASTER, the active timepiece that features TRIPLE G RESIST construction to resist the forces of impact, vibration, and G forces, plus Smart Access capabilities for simplified operation. This model is one of the first GRAVITYMASTER models to include a digital compass, thanks to the development of a direction sensor that is an amazing 95% smaller than its predecessors. The hand that indicates direction is made of carbon fiber, a first for a G-SHOCK watch.
MULTIBAND 6 allows pick up of six different time calibration signals around the globe. Of course, the time setting can be adjusted manually in areas where a signal is not receivable for some reason.
Other features include a Tough Solar power system, sapphire glass with anti-glare coating, and large buttons with anti-slip surfaces for easier operation. All of this plus a face layout designed for easy reading makes this model the perfect choice for aviators and anyone else who needs instant access to information while on the go.
TRIPLE G RESIST
Designed to withstand the shock of three forces: Gravitational dropping forces, centrifugal gravitational force, and vibration. Unmatched toughness only from G-SHOCK
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.
WAVE CEPTOR (RADIO CONTROLLED)
Receives time calibration signals and corrects the time automatically.
MULTIBAND 6 allows reception of time calibration signals from one of six transmitters around the globe : Germany, The United Kingdom, The United States, China, and Japan (two transmitters).
