Hi Omega gurus! May I humbly ask your opinion on the ff:
•Ref number
•caliber
•Ballpark
•or any details/history

Visited Omega SC here in the Philippines and the estimated checkup indicates that it is a 3681075 having a caliber 1111. I have done my research prior visiting the SC, and ever since I know it is a 1107.15 with a caliber 1120 plus it matched even on omega site against than the 3681075 Stated by SC.
But the caseback also indicates that it is a calibre 1111. If you search on the net, there's no caliber 1111 and ref 3681075 matching with my Omega Constellation which is exactly 18k solid gold.

Hoping someone can enlighten me.

Attached pics for your reference:

 

Well, 055BA3681075 is the reference for a yellow gold Constellation, but not with a diamond bezel, so I'm not sure if that is original to the watch or not. Since you have had the case back off, what are the numbers inside the case back?

There was an 1109 movement, then an 1110, and then an 1111, before it became the 1120, so I don't really see a problem with that...

Cheers, Al

 

Do you mean Yellow gold constellation and also in yellow gold strap?
Caliber 1111 is stated in the caseback display as shown on the above pic, and Omega SC also confirm it is a 1111. But look at the first pic, omega's site clearly said that it is 1107.15 compared to my watch. That's why I'm confused

 

Yellow gold bracelet is 020BA1448431, and goes with the 055BA3681075 listed above.

11071500 uses case ref. 055BA4681201X and has the diamond bezel.

I'll ask again, what are the numbers on the inside of the case back?

 

So it is indeed a 3681075 with calibre 1111. Yellow gold constellation with yellow gold band, 36mm mens size, but with what bezel? So the diamond is a customized purchased. Do I got it right sir? Thanks

 

I'll ask again, what are the numbers on the inside of the case back?

 

Serial number you mean? Its 49557072

 

There will be numbers stamped inside the case back - I need those. Not on the movement, but inside the case back....

 

All i got is the numbers on the estimated repair list. And also the cosc cert I'll attached it might help

 

Okay without the numbers on the inside of the case back it's hard to explain the conclusion that the service center came to with regards to the model number, so my guess is that the case back on your watch is used on more than one model, and there would be more than one set of numbers stamped inside. So they may have taken the wrong set of numbers as the case reference.

Either that, or the case back is off another watch, but that is less likely in my view.

So your watch is a PIC 11071500 that uses case ref. 055BA4681201X and has the diamond bezel.

Cheers, Al

 

So basically I'm correct with 1107.15 but with caliber 1111 instead of 1120 as 1107.15 is using as per omega's website?
Can you explain what you said 'case back on your watch is used on more than one model' you mean it is a Frankenwatch? Kindly explain in simpliest form appreciate the effort Sir

 

No, not necessarily a franken watch - it was common that Omega used a specific case back on several models.

 

So the caseback used for many models and there's many numbers stamped inside then the SC picked out the wrong ref?
So definitely it is a 1107.15, but why it is using caliber 1111 instead if caliber 1120?

 

Yes I'll do it asap, and yes mine is a display caseback.

 

A recurring theme here:

"Since you have had the case back off, what are the numbers inside the case back?"

"I'll ask again, what are the numbers on the inside of the case back?"

"I'll ask again, what are the numbers on the inside of the case back?"

"There will be numbers stamped inside the case back - I need those."

I do try to help but sometimes it's like banging your head against the wall...

And the 11071500 has a solid case back...if this one has a display back, then there might be an issue here - even more reason to get the numbers off the inside. Photos of the actual watch front and back would be in order as well.

Cheers, Al

 

Yes I'll do it and let u know asap. What issue? As per checking with omega SC it is authentic.
So you need the front, back and the inside of the case back where numbers to be found. Right? What else can I do or info to ease up the identification?
