My initial reaction to the OP's example was that it is either an excellent redial, or a factory replacement. I thought that because of how white it is, the different (serif) font, and "S" on "Seamaster". The anomalous narrow "chronometre" was also a question mark, though the OP has found at least one other that appears original.
I do agree that the printing is of very high quality, and is more likely representative of OMEGA production (whether original or replacement) than a superior redial.
Although I have owned the very similar model shown above, I haven't studied the dial printing variations around that period, so others would likely have more educated opinions. Any of these members may have fine insights, as well as thoughts on the interesting triple reference:
