    Hello. I've been looking to buy a Speedmaster Mark 4.5 and have gotten confused as to their serial numbers. According to my research, the Mark 4.5 was only produced in 1974 which should yeild a serial number beginning with 38(per Maddox) or 32(per Hartmann).

    But a quick search on eBay tells a different story. Of the four Mark 4.5's currently on sale there, not one has a serial that falls within the 32M-38M range.

    Here are some screen grabs:

    These serials were used '75-'84 (Maddox) or '79-'86 (Hartman).

    Any theories as to why these watches have such a wide range in numbers when they were produced for only a year and why none of them fall within the expected serial range?

    Confused. :-/

    your information is wrong, the 176.012 and also some other Cal. 1045 based modells where produced much longer, starting from 1974 untill ca. 1988. The last one was the 376.0822 ( Holy Grail) in 1987/88.

    The Maddox and Hartmann charts you refer to are for speedmaster professionals, not the autos.

    Please correct me if my inferences are wrong

    From Incabloc's reply:
    -Automatic Marks were produced for 10 years or more(?)
    -I still apply the Maddox/Hartman tables to 1045 movements.
    -the Mk4.5, as suggested by the above serials were produced for 7 years(assuming an average 1M per year of production)

    From dennisthemanace:
    -the tables apply only to 321/861/1861 serials
    -Omega was issuing these serials in parallel with 1045 serials(could there be duplicate numbers between manuals and autos?)

    Thanks for the replies.

    My 4.5 has a 46 million serial number dating to about 1984, so yes i agree, they were made for many years and not just in 1974

    That specific reference, 176.012, was made for many, many years. I don't remember the SN but I owned one that came with box and papers that was sold in 1985. They were in Omega catalogs as late as 85 too. http://www.old-omegas.com/pics/speedy85de/p56.jpg
