Thread: 7-digit Seiko serial number

  1. #1

    7-digit Seiko serial number

    My new 6100-8000 Skyliner has a seven digit Serial Number. It starts 8N0****. Should I conclude this is November 1968? (That would make sense) The movement is a 61A.

    Thanks but that one only does six digit numbers, it's what I've used before. I've read somewhere that 7 digit numbers only occurred at the end of the 60s, very early 70s.

    I've seen an explanation for the letters in the serial on another forum but can't remember where. It seems logical that N is November?

    Edit: how would it work with 3 J's

    Yep that would make it November 1968.
