This is a nice vintage Tudor Oyster Royal 7803 which dates from the 50's. 
 
The watch has a stainless steel case which measures 32mm in diameter excluding the original screw down 'Oyster' crown. For its age, the case is in good condition, showing some signs of wear.
 
The hand wound movement is running well and keeping good time for a vintage watch. 
 
The dial has an lovely patina, turning areas to a golden colour. 
 
The watch has been fitted with a brand new leather strap and a new crystal. It comes with a Tudor pouch.
