For sale is my 18k Grand Seiko 5646-7005, which I believe was produced in the early to mid 1970s. This particular reference was produced at a time when gold was extremely expensive, and marks as being one of the most expensive vintage GS sold at the time. I could be wrong but I also believe that in the vintage GS era, precious metal pieces were limited to being made for just one month each year. Watch comes on a brown leather Delugs strap. Condition: The watch runs really smoothly and has been serviced within the last year. I do believe the case has been polished. The caseback is unpolished but does have scratches. The dial conditon is in pretty good condition, though there is a very light (almost unnoticable but it is there) stain around the 1 o'clock indice and the 8 o'clock indice. Price: My ask for this piece is $2150 USD. I'm open to offers so send me a PM if interested or if you have any inquiries or need anything else. Fully insured shipping is included. Would prefer to ship CONUS, but worldwide can be discussed. Payment by Zelle or Paypal preferred. Photo Link: https://imgur.com/a/shFz3xu Timestamp Link: https://imgur.com/a/P2VwW1k
