Re: Omega Speedmaster Mark II Racing Coaxial - 327.10.43.50.

I firmly believe a 7733 is correct in the later 7763. This model was one of the very first Heuer I bought way back in the mists of time and I was a bit rocked to find a 7733 movement inside as I had thought they were all 7730.
To be honest I never found a definitive answer, OTD lists 7730 only, which was why I was surprised to have a 7733. However from samples I have seen I would say 7733 is the default for the third execution Autavia 7763C, makes sense as the new movement was introduced at that time. I sold mine listed as a 7733 movement and never had it queried.
Not sure if this would be enough for Jeff to consider updating the reference table but from my research I think 7733 is correct.
