This is a fantastic mens Omega Constellation which dates to 1966. 
 
The watch has a beautiful stainless steel case with 'dog leg' shaped lugs. The case measures 34mm in diameter excluding the signed Omega crown. For its age, the case is in very nice condition. it has some light signs of wear and a small nick on the case back. The Omega Observatory logo to the case back is in great condition. 
 
The dial is also in excellent shape with a small mark below the 4 o'Clock marker. The markers and hands are very clean. 
 
The automatic Cal.551 movement is running well and keeping good time for a vintage watch. 
 
The watch has its original signed Omega crystal and box. It has been foitted with a new leather strap with Omega buckle.
