From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, comes the new GA-1100 MASTER OF G Series GRAVITYMASTER. Uniform G-SHOCK black coloring is offset by the red, blue, and yellow accents of various components. A World Time dial that uses minimal coloring promotes readability. The bi-color molded band has a black outer surface and gray inner surface, which also creates a contrasting accent.
In addition, Twin Sensor capabilities provide instant access to direction and temperature information when needed under tough conditions.
The face of the watch is marked with large Arabian numerals at 12, 3, 6, and 9 o'clock for easy reading. The face is illuminated by a Super Illuminator, high-brightness auto LED light to ensure high visibility under virtually any conditions imaginable.
