Hi, I've some doubts on the Omega cal 1110. I've noticed multiple Constellation Manhattan + Semaster prebond with the word "chronometer" on the dial and cal 1110. Apparently from Omega website cal 1110 doesn't seem to be a chronometer certified mov. - Here is one in my possession, is it possible the Cal 1110 was chronometer certified at same stage by Omega for some models? Or is this most likely a franken? Can you help?

Prob a Franken. As you say the 1109 and 1111 were COSC certified. The 1108 and 1110 it seems were not. That said Omega have form from earlier times for putting some through certification and others not with the same calibre number. Do you have the PIC or case number for your model? If so, maybe check what movement it should have had. The case number might be stamped on the bracelet. The Pre-Bonds seem to use the 1111 or 1109 in my experience. Can you show an example where a 1110 was used?

Many thanks for your quick reply, giving my some kind of hope this is not a franken If I consider Omega putting some through certification and others not with the same calibre number.....on the bracelet I read 1448/431 - I appreciate your support to clarify this, considering I see reviews, still today some of these but also seamaster for sale with cal 1110..apparently chronometer certified...for instance https://www.zeitauktion.com/it/OMEG...AUTOMATISMO-OROLOGIO-DA-UOMO-168-1501-2104803

Those are just the bracelet numbers so not a lot of use. Sometimes they stamp the case number, of the format XXX.XXXX on there but not here. Do you have any original papers? If we had the PIC or case number we could check what calibre was originally fitted.

I did a quick search simply on "Omega Constellation Manhattan Auto" and I got the hit below which looks like yours. This one has the certified 1111 movement:

https://www.ebay.co.uk/itm/285738956053?chn=ps&_ul=GB&_trkparms=ispr=1&amdata=enc:1CeMYnEPXRT2WWDDRc_SNCw2&norover=1&mkevt=1&mkrid=710-134428-41853-0&mkcid=2&mkscid=101&itemid=285738956053&targetid=1646683156259&device=c&mktype=pla&googleloc=1006524&poi=&campaignid=17206177401&mkgroupid=136851690655&rlsatarget=aud-1165553645205😜la-1646683156259&abcId=9300866&merchantid=6995734&gad_source=1&gbraid=0AAAAAD_Lr1e7Qz8xJvxPrxFNE8m_bens_&gclid=EAIaIQobChMIz5aG59X9hAMV24lQBh1ujw7LEAQYASABEgJ-uPD_BwE

This suggests your PIC is 1500.30, if that is so, it should have a 1111, there are zero google hits for that model with the 1110 instead.

Hi, 47523170 or 47528170 one of this 2 is the serial. Don't have the PIC or original papers.
I was just watching also this vid

Well if you have the serial we could ask our helpful resident Authorised repairer Al @Archer if he would be able to look up those and see what the Omega Extranet lists (if anything). Would you be able to take a look please Al? Cheers.

Please, that would be extremely beneficial to clarify.
I also found https://www.uppsalaauktion.se/en/auctions/20231212/140-omega/
Seamster also with cal1110+chronometer on the dial https://www.zeitauktion.com/it/OMEGA-SEAMASTER-ACCIAIO-AUTOMATISMO-OROLOGIO-DA-UOMO-368-1042-2301866

Also this other seamaster with cal1110+chronometer on dial https://www.chrono24.it/omega/omega...110-acier-inoxydable-men--id33537161.htm#gref

This as well...https://www.ebay.com/itm/1263754751...S57rTBkBXvTaP6LyGQr54+Ev0=|tkp:Bk9SR8bX15bKYw

And also for these seamaster above....if looking on Omega website they all come up with cal 1109/1111 instead they all have 1110 cosc apparently

Also some user on insta https://www.instagram.com/p/C2v-qSWPgvn/

And here another one
https://www.fromjapan.co.jp/japan/en/auction/yahoo/input/n1053923706/lgk-category_cn_時計_コンステレーション

I'm starting to wonder if on Omega website some info are missing...and or if these above are genuine as apparently they should be

Appreciate your help

I don’t think it’s a Franken at all. I have the same watch with original box and papers. Received from the original owner who I’m sure never tampered with it. Cal 1110 and Chronometer on the dial. I’m sure it has never been or is way overdue for a service but still keeps incredible time on par with my 3861 Speedmaster.

Hi Aroxx, many thanks for your support and update. It'll be interesting to see (possibly) the papers. But anyway really appreciate you sharing these infos. Let's see if also @Archer is able to clarify this further.
Many thanks again

Serial numbers under 50 million cannot be looked up on the Omega Extranet - Omega wants you to buy an Extract of the Archives for those.

I did look up the bracelet, and from that every watch that this bracelet was used on - only one matches the OP's watch, and that is the ref. 15003000.

Ok So you're saying it should have cal 1111 not the 1110, right? What's your opinion according to your experience...do you think is it possible Omega got some 1110 cosc somehow as well? Many thanks

No idea what's going on there - if you are in doubt, you could ask Omega directly I guess.

If you are finding multiple examples of Omegas with Chronometer on the dial and a 1110 inside then the chances are some were indeed sent for chronometer testing. It would be odd indeed if so many had seen movement swaps. What is less likely is that they used a non chronometer movement in a watch with a chronometer marked dial. Like I said above though, if you search on "Omega 1500.30.00 and 1110" you get literally zero hits so your watch and Aroxx's aren't exactly common it seems!

It has been awhile but in my initial research I found this as a reference 368.1075 which does indeed show as having a caliber 1109/1111 on the Omega vintage archives.

https://www.omegawatches.com/en-us/watch-omega-constellation-omega-st-368-1075

I remember being curious at the time why mine was a 1110 but I wasn’t very worried about it and didn’t research further. I didn’t even realize until looking into this thread that the 1110 is just a non-chronometer rated 1111. As stated above, I’m quite sure mine hasn’t been frankened though so I have to believe it’s a legit combination however strange. Perhaps I should have dug deeper as you are doing.

This may just confuse the matter more. I don’t see anything popping up for the reference number listed on the back of the warranty booklet.

https://www.invaluable.com/auction-...a-mod-constellation-cal-111-6006-c-cce438fa5b As far I can see online there’re no spec-differences between cal 1110 and 1111, Quartz was booming in those years, perhaps they had 1110 possible temporary liabilities to consume who knows…Regarding possible Franken, it doesn’t make too much sense to swap the same Eta 2892-2. I appreciate everyone being supportive. I’ve also emailed Omega x extract from their archives…since the online service previously available…it doesn’t seem to work.
