I found this in a drawer at my parents' house. It's a Benrus watch, an American brand. It winds up and runs, but it's not accurate. There is some rust and scratches. The back of the case is engraved with "BENRUS, 20MICRON GOLD ELECTROPLATE BEZEL 10K R.G.P. BACK," and there are also engravings on the band (see photos). It's an antique wristwatch. Please refrain from purchasing if you are concerned, as it has been stored in a drawer for a long time.
