    Omega serial number and production date

    Hi,

    If a Omega Seamaster 2531.80 has the serial number 8026xxxx, is it possible to find out its production date?

    Just the nearest year would be fine.

    :thanks in advance for your kind advice.

    Omega doesn't make it easy to date modern watches. You might refer to this thread to help out a bit.

    Mine is 80391XX and it's a mid/late production 2003. Therefore, yours would be 2001-02

    The best way is to ask for your COSC certificate; there is the date of testings... it will give you an idea of the manufacture date calculating some days before tests in COSC labs.

    Bit of a blast from the past, but I wasn't aware you could ask for a copy of a COSC certificate (Marine chrono certificate from Besançon, yes) ? Can it be done by email? An idea how much it costs?

    Turns out I just picked up a 2531.80.00 with a 80381xxx serial so I've been able to ballpark date it to 2003 thanks to this thread. Seller claims it's from 2005...guess it could have been sitting in a window when he bought it...

    Yes you can. I just got off the phone with Omega and paid for 3 extracts from the archives @ 80 CHF/each. I believe that the charge the same for the COSC. You can't order these from the website if you live in the USA. I went through customer care:

    Thanks for the first hand info. I was aware you could get these extracts from Omega (I think they're laminated based on pictures I've seen) and that you could also get copies of the Besançon Marine Chronometer Certificates but not for COSC.

    Did some more research and found this Ordering your COSC Certificate from Omega | THE SEAMASTER REFERENCE PAGE that explains how to get a COSC certificate directly from Omega (I thought you would have to contact COSC directly) but apparently you need to send them a copy of the warranty cards...so I'm not sure what happens if you don't have them. Can't see a link on the Omega site to order a COSC certificate so far, only an extract from the archives (OMEGA Watches: Order Form for watches <2000)

    Apparently you can get a duplicate from COSC (see COSC - Contrôle Officiel Suisse des Chronomètres) but it's not clear how one would do that.

    The email I sent yesterday to aftersales@omega.ch as explained in the "Ordering your COSC Certificate from Omega" article linked above came back today with instructions to use the contact form instead https://ccm.omegawatches.com/en/ ...which is what I did.
