This 31mm. TUDOR Oyster Exeter is an uncommon variety. The original TUDOR movement is manual winding and just cleaned-accurate. This is a mid-size watch-not too small and looks great on the wrist. This ORIGINAL black dial is really quite beautiful; having the original pencil hands, silver gilt print and radium Arabic numerals. Black dials are hard to find and are more valuable than silver. The original OYSTER Patent crown is still present. These watches; such as the Essex, Bristol, Devon, London were all produced by Rolex in the 40’s and 50’s for the Commonwealth market. These TUDOR OYSTER watches are very collectable and becoming quite difficult to find.
