Vintage Tudor Rolex?

[SluffMcDuff]

A friend is after a birth year watch and has been offered this 1958/59 Tudor. Does it seem strange to anybody that the dial states Tudor Rolex as the model? I can't find any images of other watches like this and wonder if it's had an aftermarket dial. Others I've seen are marked Tudor Royal etc but not Tudor Rolex.

Any light that someone can shed on this would be appreciated.

That's a great help thanks.

At least it seems to be a genuine Tudor, and even if it's had a redial it is the correct dial.

Hallmarks are Birmingham 1958/59, that's where the age has been derived from as there are no papers.
