Casio's G-SHOCK brings you a fresh lineup of heavy-duty watches that are perfect for wearing in tough environments as well as on the streets to look as stylish. The design of these watches is made by a 10-sided bezel that looks like the shape of a nut. The design of the dial in the digital area specifically creates a powerful look that improves readability. This GA900AS-1A model has a black resin strap attached to a black case with a negative LCD dial and purple accents.
