Interesting Facts

Tudor was originally founded in 1926 by Hans Wilsdorf, the founder of Rolex, with the explicit goal of offering a more accessible timepiece that maintained Rolex-level dependability. The Classic collection represents Tudor's foray into sophisticated, dressier everyday watches outside of their traditional tool watch lineage.
