This is a G-SHOCK G-LIDE. The color is a skeleton blue, although it's difficult to tell from the photos. I bought it quite a while ago. I changed the battery myself, so please be aware of that. If you are concerned about water resistance, please have it checked at an authorized dealer after purchase. The backlight works. Please purchase with the understanding that this item has been handled by another person. There is no box or instruction manual. Please comment if you have any questions or would like to negotiate the price. Accessories: None Operation: Good
