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 GA900E-1A3 model comes with a black resin band as well as an interchangeable highly-reflective yellow cloth/nylon strap that attach to a black case with a negative dial and silver/orange accents.
