About Rolex

Background from the Rolex profile, not from this object's source.

Founded in 1905 as Wilsdorf & Davis, the company initially served as an importer of Swiss movements for the British market. Following the First World War, the firm relocated its operations from London to Geneva, Switzerland, to address economic and tax pressures. The organization was formalized as Montres Rolex SA in 1920.

The company has been under the ownership of the Hans Wilsdorf Foundation, a private family trust, since 1960. Throughout its history, the brand gained significant recognition for technical developments in water-resistant technology and automatic winding, notably the Oyster case introduced in 1926 and the Perpetual rotor mechanism patented in 1931.

Evidence from the maker profile

“Following World War I, the firm moved its operations to Geneva, Switzerland, to navigate economic instability and import tax pressures.”
“Since 1960, the company has been owned and controlled by the Hans Wilsdorf Foundation, a private family trust.”
