This is an amazing vintage Omega Seamaster 60 Big Crown which dates to 1972. 

It has a wonderful stainless steel case which measures 37mm in diameter excluding the oversized crown. For its age, the case is in good condition. It shows some marks and usage, this highlights that it hasn't been overly polished. It has a screw down case back with the Omega Hippocampus logo. 

The really interesting part is the blue dial, although not as bright as some of the photos may suggest, it really is a statement piece. For its age, it is in good condition with some signs of wear. The lettering is all crisp with the batons and hand clean. 

The automatic Cal.565 movement is running well and keeping good time for a vintage watch. 

The crystal shows light marks but in good overall condition. It has been fitted with a brand new leather strap with vintage Omega buckle added. The watch also comes in inner and outer Omega boxes.
