Considered to be the little brother of Rolex, Tudor watches were conceived by Rolex founder, Hans Wildorf. The Tudor watch brand was to created to pay tribute to the Tudor period of England. Additionally, it allowed consumers to gain access to a watch with the reliability and dependability of a Rolex, but at a lower price. Tudor brand watches are manufactured by Montres Tudor SA using movements supplied by ETA SA. Tudor watches were used by the French Navy for its divers, with the first Tudor Submariners being purchased in the late 1960's. Additionally the same model was used by the US Navy for its UDT and Navy Seals. Even with an aristocratic name of its own, a Tudor is still a Rolex.
