A new vintage Constellation just arrived, and it makes me confused a bit.

It's a 18K, arrow-head, the dial has Omega printed, the caliber is 354, and the caseback has 2699 number on it. Everything seems in place, but, the caseback looks like this:



What bothers me is: why it has both 2652SC and 2699? So, is this a ref 2652 or is it 2699? Also, which are the series of the movement that will match with this case? I have seen some, starting with 11xx...

Thank you very much for your help.

 

No problem with dual reference numbers on the inside of Omega casebacks, especially when they used 4 digit reference numbers.

 

I will take some photos sometime later. My caseback is exactly like the one I posted.

The Omega letters on the dial are printed, not applied. The logo is thin. The markers are arrow-head, and there is a cross. All seems original (the dial part).

 

I'll hold you to that. Just a sec while I put you on the list of members who owe pictures.

Correct for a 2699. The 2799 was otherwise identical except it has the applied logo.

 

Like this ?



Sounds like my 2652
