Hello, I just impulsively bought my first Constellation. It was late, I just refreshed my auction site one last time before going to bed and it appeared with what seemed a very fair "buy now" price, so I bought it. I recieved it yesterday and it looks amazing! But I checked the movement and started to be skeptical. That's why I come here to ask you about the watch and if it's genuine or not. Mostly because from what I could read, it should have a 1011 if it's chronometer. Case number ST 168 0056 Blue dial with white indexes and hands, date and chronometer certification Caliber 1012 without anyting written on the main bridge, serial number 3670XXXX Thank you for your help! Here are a few pictures:
Hmmm Check this. https://omegaforums.net/threads/full-list-of-omega-calibers-from-1894.42412/ Says a 1012 should be in a Seamaster.
Thanks, yes it confirms that I should have a 1011. What surprises me is the global good condition of the watch. I clearly didn't have been worn much so why replace the movement, and by the wrong one... That's sad!
Omega vintage database also shows it in Constellation, Geneve, et. al., but 1012 is not a chronometer rated caliber? https://www.omegawatches.com/vintage-watches?v_watches_calibre=2792
This is what you find on Omega's site https://www.omegawatches.com/watch-omega-constellation-c-st-168-0056/ So the movement ought to be a 1011, which is the chronometer implementation wheras the 1012 is the "normal" movement. You could ask for an extract of the archives or - and that might be cheaper - a copy of the COSC cerificate to be 100% sure.
Yes sorry, I'm not sure of it's name but I'm talking about this one: Since usually that's where infos like numer of jewels are written no?
Yes that info is there, but get a loupe and look at the small circular area in a lighter shade of brass that has the word Omega. The caliber should be in there, IIRC.
I think this is the watch I had my eye on on eBay. No movement shots in the advert if I remember correctly. Thought it looked nice but I couldnt recall having seen a blue dial like this before.
Nope it wasn't on ebay and stayed for sale only a few minutes before I bought it. Do you have the link of the one you're talking about?

You don't need a loupe. Its all there in the OPs own pic (no. 6) where the rotor is on the 9 o'clock side of the watch. It says Swiss Omega 36702059 (smudge)12 So there's two possibilities: either someone at Omega bungled when he or she printed the SN and the calibre. Or someone e(x)changed the movement at some time for some reason. If you ask for a copy of the COSC certificate, you'll soon find out if this movement was ever tested. And if it wasn't, which unfortunately must be feared, you'll have the certainty that case and movement did not leave the Omega factory together.
I don't believe Omega will provide a COSC certificate for a 40+ year old watch. COSC does not sell them to individuals. From the COSC web site: "What information can the buyer of a certified chronometer watch obtain from the COSC ? None. The COSC is the repository of analytical results that belong to its customers (the watch brands). It does not have the authority to disclose information to anyone other than the legitimate owners of those results. The buyer should contact the head office of the brand to which the chronometer belongs." I doubt there is a way to get this certificate, even if one exists.
