Is it an unworn Omega Seamaster Calendar or something else ?

    Can this watch be factory original as its owner claims, supposedly an unworn piece?

    I expected a different crown for a Calendar and the "S" of Seamaster makes me think it's from the 60s, but I thought these watches were from the 1950s. I suppose it must be a 2627 case with caliber 353 but no information on that so maybe it is something else. I'm also wondering if the strap and buckle are period correct. I thought the logo on a square buckles came later.
    So I'm thinking case from the 50s. Dial from the 60s. buckle from the 70s. Crown? Hands?
    Or am I completely wrong?
    What do you guys think?

    Service dial, service crown, service strap/buckle. They may be genuine Omega parts, but they are not original to the watch, nor truly "correct" for it.

    The case is indeed sharp but too scratched to be "unworn". I concur with the above, not that you need it.

    This is how things should look for that case:

    On my two, the bezel is raised above the lugs some. Interesting to see these are slightly different.

    Beg to differ with you, but only very slightly. The dial is an Omega replacement dial and is correct for this case reference.

    It is not original, as you pointed out.

    The case itself is in excellent condition. It too may be an Omega replacement part.

    There is really no way to know for sure.

    The date at 6 movement is a calibre 355. Likely from the 1950s. I can’t say for sure from the one picture that shows the back view of the case, but it looks like a gold shell. Speaking for myself, there is not a lot about that watch that would bother me.

    The screw back case (Ref. 2627) generally contains a cal. 353, but I have seen some with cal. 355. These are both date at 6.

    The later Ref. 2757 snap back case ("beefy lugs") are all cal. 355.

    The main difference is that the cal. 355 has the swan's neck fine regulator.

    I mean a dial made by Omega (or their contractor) that was made specifically to replace the original dial if damaged.

    Both are possible. I think the cases shown here are later than what I have?

    Not sure on this one, it's a caliber 502 where the case is dual marked KX 6275 and also 2627.

    The stick markers. None of these watches as near as many of us have seen were originally made with stick markers. Most are shields and arrows or numbers and arrows.
