This is a G-SHOCK DW-5600R 1AJF. It's a re-release of the original Origin model, made by Yamagata Casio. I purchased it around this summer. It's currently sold out on Casio's official website, and I finally managed to get my hands on one after searching around. It comes with the box and instruction manual. I haven't used it too heavily, but please excuse any minor scratches or dirt. Please only bid if you are not seeking a return. It's a G-SHOCK, so I think you'll be able to use it for a long time.
