Rolex has been a pioneer of fine wristwatches and timepieces since 1905 and today the company's fame is unrivaled not only in haute horology, but as a brand that epitomizes luxury and distinction. Trademark innovations include the first waterproof wristwatch and their advanced Perpetual self-winding mechanism. Their record for excellence in design and performance has led Rolex to the top of the mountain, literally: Rolex watches accompanied the first explorers to the top of Mt. Everest and K2, among other grand adventures. Brand ambassadors Roger Federer, Sir Jackie Stewart, Lindsay Vonn, and Michael Bublé speak to the massive popular appeal of Rolex watches worldwide in sport, entertainment, and pop culture.
