Founded in London in 1905 by Hans Wilsdorf and Alfred Davis, Rolex moved to Geneva in 1919. The company is the biggest and most famous luxury watch brand in the world, producing around 2,000 watches a day. Rolex has been consistently innovative throughout its lifetime, producing the first waterproof watch, the first watch with an automatically changing date, the first watch to show two time zones at once and the first wristwatch to earn chronometer certification.
