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 Daytona
Rolex became the official timekeeper of the Daytona International Speedway in 1962, and to mark the occasion, Reference 6234 was replaced with Cosmograph Reference 6239, introduced in 1963 as the first chronograph from Rolex nicknamed "Daytona". However, the original Reference 6239 did not include "Daytona" on the dial (and was in fact nicknamed "Le Mans" for the famous 24 Hours of Le Mans race). In addition to the chronograph features, the wristwatch featured a bezel engraved with a tachymeter, as the watch was intended for racing drivers.
