Omega Ref 270591 Chronograph (1963)

Hello people,

I am a bit of a collector of the 101.010 and i know pretty much what i am doing in this department. I have come across a watch though, that i need a little help with. I am thinking of puchasing this 18k rosegold 3 register chronograph from 1963: The movement is a very good looking 321 which dates back to 1963, the dial is in great shape and shows no signs of a redial. The case is unposished and has wonderful sharp edges. The "swiss made" is hiding but where it should be below the six.

My problem is that i can't track down the case model with the ref 270591... If it weren't for the lugs i would swear its a 101.010-63 but the way these look.... That reference number also just does not pop up anywhere and i do not have the books to look for it. Does anyone of you wonderful people know what this reference numer is? Or even better has seen this watch model before.

Some images added.

Thanks for your help and all the best for you.

I dont have any experience on this reference but the perfect finish on the lugs and Pushers doesn‘t seem to match with the Rest of the Watch for me

Yes, i also thought so, although in real life the watch does look a lot more consistent. "270591" seems to be the case model number, which is more of an internal Omega code than anything else... the little stamp (on the right) on the inside of the case back seems to be the Hugueinin Frères "sign" a case maker from Switzerland. That also seems consistant. I am just so curious how this watch came about and if anyone knows anything about it. Thanks for your reply!

OK, to clear this threat and my piece of mind: a fairly reknown Omega dealer just let me know, that this watch is indeed not an original and boasts a rebuild case, plus the engravings in the case back do not look original. Thanks

I agree. The case is most likely from a modern museum collection piece paired with older dial and wrong hands. The 270591 reference is not only imaginary, it does not fit any of the period referencing norms, neither 4 digit or the later 6-digit ones, with or witout the dashes. Poor fakery.

Actually the "1" in the Geneva Key is a mark for Wenger, SA:

However, I have serious doubts whether that case ever saw the inside of the factories of Wenger or Omega. IMO, this is a vintage fake gold case. Please have it tested for gold content. This is not the only example like this.

Please Google "Omega Constellation 091919" and see what comes up. A rogues' gallery of fakery.

Sometimes a genuine vintage Omega gold caseback will have both a case reference (on older watches like this, generally 4 to 7 digits with a decimal point) and a case serial number (which may be 6 digits depending on who made it), but beware of any Omega caseback which only has a 6 digit serial number.

I'm sure I may be wrong with a particular model, but I'd rather be safe than sorry.

Thank you gatorcpa, in the end i opened up all my other 18k 101.010's and that really bullet proofed the whole "case". Not only are the engravings way to soft, the actual design of the stamps look way different. Let alone the material of the case back itself... you can never be careful enough these days!

(First image is the fake, second is the real deal)
