This is a very nice vintage Omega Seamaster which dates to 1966. 
 
The watch has a larger case which measures just over 34.5mm in diameter excluding the signed Omega crown. A great size for a 60's watch. For its age, the case is in very good condition showing light signs of wear and marks. It has a screw down case back with the Omega Hippocampus logo in the centre. 
 
The silver coloured dial with its simplistic hour markers is also very clean with just minimal wear.  The Omega logo and wording is very clean. 
 
The automatic movement is running well and keeping very good time for a vintage watch. 
 
It has been fitted with a brand new leather strap with Omega buckle as well as a new crystal. It comes in a vintage Omega box.
