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.

Historically, Tudor watches have been manufactured by Montres Tudor SA using movements supplied by ETA SA. Since 2015 however, Tudor has begun to manufacture watches with in-house movements. The first model introduced with a in-house movement was the Tudor North Flag. Following this, updated versions of the Tudor Pelagos and Tudor Heritage Black Bay have also been fitted with an in-house caliber.
