Thank you very much for viewing. I believe this is a vintage Casio watch. I think it's from around the 1980s. There aren't any particular distinguishing features, but it's in relatively good condition, and all the functions, such as the light, chronograph, and time setting, work without any problems. Unlike plastic digital watches, I'm listing this because I think there are people who collect stainless steel digital watches as a hobby. I've cleaned the entire watch and lightly polished it. There are some fine scratches if you look closely. (This is just my personal opinion.) The battery has been replaced with a new one. The stainless steel still has a nice shine, and the buttons operate smoothly. This is a vintage item, so please understand this before purchasing. Thank you very much.
