Rolex SA and its subsidiary Montres Tudor SA design, manufacture, distribute and service wristwatches sold under the Rolex and Tudor brands. Founded by Hans Wilsdorf and Alfred Davis in London, England in 1905 as Wilsdorf and Davis, Rolex moved its base of operations to Geneva, Switzerland in 1919.

Rolex has three watch lines: Oyster Perpetual, Professional and Cellini (the Cellini line is Rolex's line of 'dressy' watches) and the primary bracelets for the Oyster line are named Jubilee, Oyster and President.

Rolex watches vary in price according to the model and the materials used. In the UK, the retail price for the highly sought-after stainless steel 'Pilots' range (such as the GMT Master II) starts from GBP £5,250. Diamond inlay watches go for considerably more.The most expensive Rolex ever produced by the Rolex factory was the GMT Ice reference 116769TBR with a retail price of $485,350.00. A Forbes Magazine article on the Swiss watch industry compared the retail value of Rolexes to that of competing brands Corum, Universal Genève and IWC.
