Pre owned. Estate sale find. This is not working. There is no crown and I don't believe there is a stem but I'm not an expert. The dial has something at the 2pm mark that I can't get off with simple gentle wiping. The watch band is not in good shape but functional. I wiped the band down with a baby wipe. Please see photos for condition. Ask if any questions. The back of the watch "10k RGP"
