·Hi, i sorry for signing up and going straight to pick your brains, but I am a frequent member of other watch forums and reckoned that this would be the most appropriate place to discuss what appears to be a mystery to me. 😀
I recently bought an Omega Seamaster Cosmic from 1970 and from the dial I identified it as reference 166.026, identical to this one.
Now, on the back of the case, the reference number says 166.036, which would point to a later model with cal. 752, so I was assuming that the case had been swapped at some point. All characteristics of the movement pointed to 565, but the watch was stopping randomly, so I took it apart and the movement was indeed a 565 (and that a screw had come lose, blocking the balance and/or rotor).
Now to my dilemma: The case back says misleadingly ref. 166.036, while inside the case, the right reference number is stamped in, ref. 166.026. Please see the attached pictures.
Is this common, or how would you explain it?
Thank you!
