This is a Casio G-SHOCK. The model number is GN-1000C. I believe it's the previous generation Gulfmaster. I bought it used before summer and have been using it. It is currently running. I think there are no particular problems with the operation. I don't think there are any noticeable scratches on the glass surface. There are some areas where the color of the bezel's dial has peeled off. The back of the strap is yellowed. Also, there are traces of the film-like coating on the surface of the strap peeling off. The white Gulfmaster is recommended because not many people wear it, and it stands out. I am selling it to organize my collection. Please understand that the condition assessment is based on my personal judgment. Watch only. There is no box or other accessories. Please ask any questions in the comments.
