This is a very attractive vintage Omega Constellation. 
 
The stainless steel case measures a large 35.5mm in diameter excluding the signed Omega crown. It has a screw down case back with the Omega Observatory logo on the rear. This logo is very crisp. 
 
The Automatic Cal.561 movement is running well and keeping very good time. It was serviced by the previous owner in November 2024 and will comes with the receipt. 
 
The dial is in very good condition for its age with just a very minor amount of wear. 
 
 
The watch has been fitted with a brand new leather strap with vintage Omega buckle. The watch comes in a vintage Omega box.
