I was recently lucky enough to find this July 1971 production near NOS JDM Speetdimer 7017-6040. It looks as if it has been worn only a handful of times over the past fifty years. The case and original signed bracelet retain their original finish. The previous owner added a clasp extender. In addition, the watch came with its original hang tags and sales receipt. The only items missing are an original box and owner's manual. I found a correct box on ebay from a seller in Japan, but at $700., that's a hard pass right now. Thanks for looking.
