    Hi,

    I recently got my hands on a beautiful tropical dial 105.003. The case, case back, dial and the overall looks of the movement are all OK but the serial number on the bridge of the 321 caliber is a 5 digit number starting with "1". I am pretty certain that this is not the original part of the movement, but can't think of a reason why this would have had to be replaced. Any thoughts? Also, is there any other spot where the correct serial number of this watch could be seen?
    Cheers

    Hi, pictures would help a great deal.

    From the sounds of it, you have a Franken, but pics sure would help

    Symmetric clutch bridge, you got yourself a very very old 321. Likely belonging to the late 50s.

    Yes but that is not even the slightest concern.

    I believe the symmetrical clutch was used up until the early '60's. MWO says it's correct for 105.002 and 105.012-63.

    So this is likely a Franken Speedy with an earlier movement inside then.. Well, that I can live with :)
    And this consequently makes the serial number a secondary issue now.

    It is a Franken watch then.
    Now the $1mil question: you think I should keep it or return it?

    Depends on what you paid. If you paid the price of an original watch, then absolutely return it. If you bought it at an incredible price, I'd keep it (and maybe source an old, period correct sweep hand and just forget about the movement) IMHO.

    Replacement parts does not necessarily equal a Frankenwatch.

    Personally, as long as the parts are period correct. You got yourself a very nice edwhite. Movement no. is least of my concern... it is just like an engine swap in a vintage car when u blew ur original one. As long as the swap is the same engine, it is fine. However I would devalue the watch none the less.

    Yes but the whole movement is an earlier one as I understood from the above posts...

    @cagkut I agree with him. The chrono hand just looks wrong, so I would personally source the period correct hand for that. However, if the movement works and it doesn't bother you that it might have come from a different Omega, then just live with it. Especially if it's a piece you intend to wear regularly. If it's a collector's item to be stored in a vault, then your priorities would probably align differently I suppose.

    Is that dial original and not re-lumed? I can't really tell from the pics. It really looks like a decent example overall.
