This is a vintage Omega Constellation which dates to 1963. 
 
The watch has a gold capped case which measures 34mm in diameter excluding the signed Omega crown. The case shows some signs of wear mainly to the lug ends. 
 
The automatic Cal.561 movement is running well and is keeping good time for a vintage watch. 
 
The dial shows some light signs of ageing. 
 
The watch has been fitted with a brand new crystal and a new leather strap with vintage Omega buckle fitted. It comes in a vintage Omega box.
