The GRAVITYMASTER G-Shock series was conceived and developed as aviation timepieces with pilot-friendly functions. The base colour is the olive green seen on flight jackets worn by pilots. The second hand and inside band surface are highlighted with orange, which can often be found on the inner lining of a flight jacket, which creates a look that is very fitting for GRAVITYMASTER Series timepieces. This model offers a compass and thermometer in addition to the features that make G-SHOCK the toughest watch in the world.
