Rolex
Rolex SA () is a Swiss luxury watchmaker. Originally founded as "Wilsdorf and Davis" by Hans Wilsdorf and Alfred Davis in London in 1905, the company registered "Rolex" as the brand name of its watches in 1908. In 1919, the company moved its base of operations to Geneva, Switzerland in order to avoid heavy taxation from a recovering post-war Britain, and "Montres Rolex S.A." was registered as the new company name by Hans Wilsdorf in Geneva in 1920. Since 1960, the company has been owned by the Hans Wilsdorf Foundation, a private family trust.
Rolex Yacht-Master
In 1999, Rolex discontinued the model two-tone 68623, replacing it with the two-tone model 168623 in 2000. The difference between the two models are in the upgraded movement in the 168623, and the heavier 18-carat gold links (the links in the 68623 are hollow).
