This Omega dates from 1958. It has an exceptionally attractive dial, being black with gold hands, hour markers and inner minute markers. A striking design. For its age, the dial is in very nice condition. There is only 1 visible mark that runs from the 11 O'clock through the logo. This is only visible in certain light. 
 
The automatic Cal.501 movement is running well and keeping good time for a vintage watch. 
 
The case measures 34.25mm in diameter, excluding the large Omega crown. The snap on case back is nice and tight and has the word Seamaster etched onto it. For its age, the case is in nice condition with some signs of wear.
 
The watch has been fitted with a new crystal and a new leather strap with what is possibly a used aftermarket buckle. The watch comes in a vintage Omega box.
