The De Ville collection was started by Omega in 1960 to sit between the dressier yet capable Constellation and the capable yet dressy Seamaster. Over the next two decades, the De Ville name found its way onto some great watches from Omega, although being seen as a bit of a third tier option at the time.
The Caliber 930 is believed to be produced in only 10,000 units spread between 5 different models, this 1969 Omega De Ville 146.017 is one "rarebird", especially with his elastic bracelet 1067/557.
