Casio G-Shock GMD-B800 Watches

Introducing new compact G-SHOCK model that is great choice for women who prefer mannish G-SHOCK styling.
These models add a new selection of colors to the G-SQUAD lineup of sports watches that make daily training more fun and effective. The size of the GMD-B800 case is approximately 3 mm smaller than the case of the popular G-SHOCK GBA-800, which makes it the perfect choice for those with smaller wrists and those who prefer a more compact watch.
The two summer nuance colors of the GMD-B800 model go well with a wide range of fashion items. A back protector cusions impact, while block coloring and new materials create designs with plenty of visual impact.
