Your watch most likely started life in the 1950s as a Tudor Reference 7809 Oyster Prince. The dial was redone. I've seen a number of Tudor watches where the dial was redone with Rolex looking dials. An analogy would be putting a Cadillac badge on a Chevy. I acquired a Tudor 7809 many years ago where someone did just that (plus a couple diamonds). I would not buy something like that today, but 30+ years ago I thought it was kind of cool.
