Founded in London by Hans Wilsdorf, relocated to Geneva in 1919 to be inside the Swiss watchmaking trade and closer to its movement suppliers.
Founded by Hans Wilsdorf in London in 1905, registered as 'Rolex' in 1908, relocated to Geneva in 1919. Rolex's modern identity is built on three pillars: precision (the 1910 Bienne precision certificate and the 1914 Class A certificate from Kew Observatory, both predecessors of the modern COSC, which itself dates to 1973), reliability (Oyster case, 1926), and the in-house manufacturing capability that allows the brand to produce nearly every component itself. The Submariner, GMT-Master, Daytona, and Datejust are the most-collected sport-watch families of the 20th century; the modern product catalog is sub-1M units per year across all references.
