Blue on blue g shock inspired? watch, we are not sure. It's definitely a casio watch. This watch is in used condtion with plenty of life left in it. The light in it is multicolor, so when you hit the light up button it illuminates the coolest multi-colors! This watch is pictured without a battery, and will not have one included because of transit reasons. Bundle another favorite item to save even more! Thanks for shopping my closet 😊
