Rolex is the company name. They have two lines of watches one is called Rolex the other Tudor.
Now its getting complicted.....
If you see a watch with Tudor and Rolex on the dial, that would be fake/redial. This was never produced.
Very old Tudor watches had a 'Rose' logo, the Tudor rose. They changed that logo to a shield.
Older Tudor watches had the Rolex logo on the crown and Rolex on the back, the dial had only the Tudor logo.
Newer Tudor watches do not have any Rolex logos anymore.
Rolex watches had never any Tudor logos on them.
The watches have the same warrenty, can be serviced at the same Service Center, are produced at the same factory.
Rolex watches have a Rolex movement. Tudor watches have a mod. ETA movement. That might change in the future and they will have Rolex movements too. But only Rolex knows.
