This is a very nice Omega constellation which dates from 1967. 
 
It has a gold capped case which measures 35.2mm in diameter excluding the signed Omega crown. For its age, the case is in nice condition. There are some signs of wear including scratches. Overall still very good. The case back has a Gold Omega Observatory logo which is in good condition. 
 
The automatic Cal564 movement is running well and keeping good time. The previous owner had this serviced, along with another constellation that I have from them. However, the receipt was lost. 
 
The dial is in very good condition for its age with very limited signs of wear. 
 
The watch comes on a vintage Omega bracelet and in a vintage Omega box. It has also been fitted with a brand new crystal.
