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
The second series Daytonas used a sapphire crystal (in lieu of the acrylic crystal of the original series); the case diameter grew from on the original to for the second series; the dials were now glossy; and the sub-dials were now largely the same color as the dial, with an outer track in a contrasting color. These later series Daytonas, pre-dating in-house movements, were accurate and reliable; they were produced in limited quantities from 1988 to 2000.
