This is a very nice vintage Omega Constellation 1431 from 1986. 
 
It has a very interesting speckled dial which is in nice condition for its age. 
 
The case with integrated bracelet is in good vintage condition with some signs of wear. It comes with extra links. 
 
The quartz movement works as it should and comes with a spare battery. 
 
The watch comes in an Omega box.
