Rolex SA is a Swiss manufacturer of mostly mechanical wristwatches and
accessories renowned for their dependability, prestige, and cost
(from a few thousand to more than one hundred thousand U.S. dollars).
Rolex watches are considered status symbols by many.
Rolex is the largest single luxury watch brand by far, with estimated
revenues of around US$ 3 billion (2003). Business Week magazine ranks
Rolex #71 on its 2007 annual list of the 100 most important global brands,
top among all watchmakers.

Rolex SA was founded in 1905 by the German Hans Wilsdorf and his brother-in-law,
Alfred Davis. Contrary to popular belief, Hans Wilsdorf was neither Swiss, nor a watchmaker.
Wilsdorf & Davis was the original name of what later became the Rolex Watch Company.
They originally imported Hermann Aegler's Swiss movements to England and placed them
in quality cases made by Dennison and others. These early wristwatches were then sold to
jewellers, who then put their own names on the dial. The earliest watches from the firm of
Wilsdorf and Davis are usually marked "W&D" - inside the caseback only.

Hans Wilsdorf registered the trademark name "Rolex" in La Chaux-de-Fonds,
Switzerland, in 1908. The word was made up, and its origin is obscure.
One story, which was never confirmed by Wilsdorf, is that the word "Rolex"
came from the French phrase horlogerie exquise, meaning exquisite clockwork.
Another is that the name was chosen to indicate movement when spoken in English.

The Wilsdorf & Davis company moved out of the United Kingdom in 1912.
Wilsdorf wanted his watches to be affordable,[citation needed] but taxes
and export duties on the case metals (silver and gold) were driving costs up.
From that time to the present, Rolex has been headquartered in Geneva,
Switzerland, though the company owns facilities in other cities (Bienne, etc)
and continents (North America, Asia, Australia, etc).

The company name Rolex was officially registered on 15 November 1915.
It is thought this change was part of a drive to popularize wristwatches,
which at the time were still considered a novelty largely for women
(pocket watches were more common). Wilsdorf was said to desire his
watch brand's name to be easily pronounceable in any language.
The company name was officially changed to the Rolex Watch Company during 1919.
It was later changed to Montres Rolex, SA; and finally Rolex, SA.

Rolex SA is a corporation initiated and originally funded by Hans Wilsdorf
and the Aegler family. According to corporate documentation, the Rolex SA
company can never be sold, nor can shares in it be traded on any stock market.
