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.
Tudor Watches
The first Tudor watches produced in the 1920s and 1930s bore a simple Tudor signature on the dial, with the horizontal bar of the T lengthened above the other letters. On some rare pieces, the name Rolex also appears. Around 1936, the logo changed to the name in Gothic characters accompanied by a shield bearing the Tudor rose, emblem of the long-reigning English Tudor dynasty. In 1947, one year after the official launch of Tudor Montres SA, the shield was removed and the rose appeared alone with the brand name. From 1969 on, the shield resurfaced without the rose. The shield remains as the logo on all Tudor watches while the rose is now used on the winding crowns.
