Yes, I know. The question about authenticity has popped up again in a Seiko forum. My apologies. I received a JDM Seiko from one of a few respected sellers. The watch is a limited edition diver. The JDM model is a different model number than North America, though I believe the total number produced (in this case 2500) is global production. The watch papers, hang tags, UPC code all line up. The case, crystal, appear excellent, hands appear crisp, as do the numerals in the date window, movement number is clear and present in the 6:00 position on the dial. Movement hand winds smoothly. I have not removed the caseback, as I don't have a tool to do so. The question, which causes my suspicion is that this is serial number 0001 out of 2500. This serial was shown on the Hodinkee review, Monochrome, as well as the press photography of the watch. The piece I currently have has a protective blue dot on the caseback, and is lined up at the 8:00 position in rear view. Press photos, etc have shown 0001 to be aligned at 4:00. The polishing of the watch, bezel, overall finish seems on par with modern Seikos. Two questions arise- should I be skeptical about the watch or its authenticity? Could this be a press / marketing watch that was distributed and then returned? Why would there now be a blue dot on the caseback? Is there any way to verify any of this history or questions? (Sorry, that's more than two questions) I am reasonably new to Seikos, though I have some history with the 6105, as my father wore one extensively in the 70s and 80s, being a hobbyist diver. I can of course post images later.
