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 word was made up, but its origin is obscure. 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 was also short enough to fit on the face of a watch. One story, never confirmed by Wilsdorf, is that the name came from the French phrase horlogerie exquise, meaning “exquisite clockwork”. 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.
In 1914 Kew Observatory awarded a Rolex watch a Class A precision certificate, a distinction which was normally awarded exclusively to marine chronometers.
In 1919 Wilsdorf moved the company to Geneva, Switzerland where it was established as the Rolex Watch Company. Its name was later changed to Montres Rolex, SA and finally Rolex, SA. The company moved out of the United Kingdom because taxes and export duties on the silver and gold used for the watch cases were driving costs too high.
Upon the death of his wife in 1944, Wilsdorf established the Hans Wilsdorf Foundation in which he left all of his Rolex shares, making sure that some of the company’s income would go to charity. The company is still owned by a private trust and shares are not traded on any stock exchange.
In December 2008 the abrupt departure of Chief Executive Patrick Heiniger, for “personal reasons”, was followed by a denial by the company that it had lost SwFr1 billion (approx £574 million, $900 million) invested with Bernard Madoff, the American asset manager who pleaded guilty to an approximately £30 billion worldwide Ponzi scheme fraud.
