The "BAR" value indicates the number of atmospheres to which water resistance is ensured. 20 BAR means water resistance to 20 atmospheres. Watches marked "200m" have the same water resistance as 20 BAR watches.

This ground-breaking CASIO system for analogue movements achieves multi-functionality and easy operability simultaneously through a combination of multiple motors and an electronic crown.
Tough Movement
Tough Movement
TOUGH MOVEMENT is a CASIO-original thin analog movement that is packed with a host of amazing features and functions. A MULTIBAND 6 function makes it possible for the watch to receive calibration signals for Japan (two signals), China, the United States, England, and Germany, for true international timekeeping. Movement durability and integrity are ensured by hybrid mount construction to protect against damage and by auto hand home position correction to keep settings accurate. A Tough Solar power system generates power from even small amounts of fl uorescent lighting and stores it in a secondary battery to help keep power-hungry functions running. The result is a totally new thin analog radio-controlled solar movement that embodies some of the very best technology that CASIO has to offer.

Color Variations


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.

Designed to withstand the shock of three forces: Gravitational dropping forces, centrifugal gravitational force, and vibration. Unmatched toughness only from G-SHOCK

Smart Access
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.

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).
