More information about this movement:
As with the calibre 562, there is an ongoing debate about whether calibre 752 powered some Omega Constellations. The Omega database indicates that calibre 752 powered the integrated bracelet Constellation model 166,0252 and ST 366,0857. However, the Omega Museum document, Nomenclature des calibres Omega, does not list the 752 as having been fitted into Constellations. There may be several explanations for this disparity.
The above models were produced after 1975 when the Swiss meltdown was in full swing. They were produced during the changeover to the 1000 series calibres and they may have only been produced for the Japanese market. I have seen three examples of Constellations housing calibre 752s – all of which were originally located in Japan. While a sample of three coming from one country is not large enough to state with certainty that some 752 chronometer and non-chronometre grade movements found their way under the Constellation livery, they do present an argument for open-mindedness until the matter can be proved one way or the other.
