Working. Used. Original box. Original strap. Original buckle. I am not sure of the case material? It does not appear to be stamped gold? I am not familiar at all the with Omega watches from this period (1980’s). The rear has been engraved (see photos). Please look at the photos for more details. Feel free to contact me for more information. I took this to my watch guy who put a new battery in it and confirmed it’s authenticity. The box is not perfect. The watch is in fair condition cosmetically. It would be helpful if someone could tell me if the watch body is gold? The back is stainless.
