Rolex SA is a Swiss watchmaking manufacturer of high-quality, luxury wristwatches. Rolex watches are popularly regarded as status symbols and BusinessWeek magazine ranks Rolex No.71 on its 2007 annual list of the 100 most valuable global brands. Rolex is also the largest single luxury watch brand, producing about 2,000 watches per day, with estimated revenues of around US$3 billion (£1.75) (CHF3.02 billion) (2003 figures).

In 1905 Hans Wilsdorf and his brother-in-law Alfred Davis founded "Wilsdorf and Davis" in London. Their main business at the time was importing Hermann Aegler's Swiss movements to England and placing them in quality watch cases made by Dennison and others. These early wristwatches were sold to jewellers, who then put their own names on the dial. The earliest watches from Wilsdorf and Davis were usually hallmarked "W&D" inside the caseback.

In 1908 Wilsdorf registered the trademark "Rolex" and opened an office in La Chaux-de-Fonds, Switzerland. The company name "Rolex" was registered on 15 November 1915. The book The Best of Time: Rolex Wristwatches: An Unauthorized History by Jeffrey P. Hess and James Dowling says that the name was just made up. One story, never confirmed by Wilsdorf, is that the name came from the French phrase horlogerie exquise, meaning "exquisite clockwork" or as a contraction of "horological excellence". Wilsdorf was said to want his watch brand's name to be easily pronounceable in any language. He also thought that the name "Rolex" was onomatopoeic, sounding like a watch being wound. It is easily pronounceable in many languages and, as all letters have the same size, allows to be written symmetrically. It was also short enough to fit on the face of a watch.
