The Constellation range appeared at Omega in 1952. The movements are chronometer certified and the case backs are engraved with the image of the Geneva observatory as well as eight stars.
The shape of the case is called "C Shape" on this reference, a variation of the cushion case. A brushed bezel and chamfers are also included and give a beautiful play of light to the whole.
You can follow the review of a similar model in this blog post:
Condition: Superb condition! The dial was manufactured by Beyeler (subcontractor Rolex, Omega...). New bottom gasket. Case with superb edges. Very good condition for its 49 years.The movement has been completely overhauled, this Omega works perfectly.
