that's a major omission on this watch. the incorrect case. probably the previous owner or the one before him replaced the case without knowing the essential character of the faceted lugs. when i bought mine in 2008, i dint even notice the facets, while all i wanted was a premoon 321. my friends even suspected that my 321 watch was not original because they found the case with unusual lines and larger in size. at that time, there was no reference nor review available on the net to confirm my cb66, even from the concluded omegamania. i held on to it anyway, and not long after, it appeared that mine is a rare cb66 in a very limited production.
