It appears to be a G-SHOCK MUDMAN model. I'm not very knowledgeable about watches, so I don't know the details, but the back cover is engraved with GW-9025A. It's been about 20 years since I bought it, but the time is still accurate, with a deviation of only 2-3 seconds from the time signal, and the light still works. There are some minor scratches from everyday use (the scratches on the "G" in the third photo are an example), so please refrain from purchasing if you are concerned. There are also minor scratches on the band, but there is no deterioration such as tearing. There are no accessories, and this is a sale of the watch body only.
