This is a nice vintage Omega Seamaster with a quartz movement. 
 
The watch case measures 35.3mm in diameter excluding the crown. For its age, the case is in good condition. The case back has the Omega Hippocampus logo. 
 
The hour hand sets conventionally where as the minute hand sets by pressing a button in the centre of the crown. 
 
The dial is in good condition with light signs of wear. 
 
The watch has been fitted with a brand new leather strap and comes in an Omega box.
