Hi there, The watch I'm wearing is my grandfathers. I restored it and on the invoice they stated it was : Omega ref. 2635, number 12189071, Cal. 342. I can't find the combination between the ref. and caliber anywhere on the internet. And I never have seen a dial with only the even numbers. Can anyone help me out and give some more information?

Allowed some more knowledgeable members tell you about that.
Thanks for looking but my cal. is 342 and I can't find this cal. combined with the 2635 (354 is normal).
There is no normal. Omega states 341 and 354, a lot of these records are incomplete. Your watch may have been fitted with a 342 because it is a secondary seconds. It is possible that the invoice is wrong and the watch is a 2636 with secondary seconds. Have you opened up ? Do you have photos of the inside of the back?
