It is well known that the Constellation line was developed in response to the enthusiastic take-up of the limited edition Omega Centenary 2499 and 2500 models. Featuring high-grade chronometer movements and elegant case and dial ensembles, the Centenary models heralded a new high point in precision watchmaking.
The first Omega Constellation to be assembled was the above calibre 352 RG model in case 2648 (click on pictures for larger view). The case, with plumped middle, lyre-shaped lugs and chamfered bezel, was identical in design to the Centenary models, the exception being the introduction of an observatory medallion on the outer case back.
The very first examples of the Omega Constellation 2648 to come off the production line in 1952 are believed to have been 18 karat gold cased models with slightly grained silvered dials, upon which a ‘cartouche’ appeared with a printed Omega logo. This dial design was also used in some Seamaster 2520 chronometer models. However the life span of the dial design was very short in both lines, and was soon replaced with domed ivory and guilloche dials.
Thus the above 18 karat Omega Constellation, with sharp case and dial in good condition for its age, can claim at least four firsts: first model number, first movement series (352 RG), first dial design and one of the first examples to come off the initial production run in 1952. A handful of firsts that make this example one of the rarest Constellations in existence.
