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.
Ferdinand Alexander Porsche
After the family decided to change the company's legal form and to keep the family out of its management, Ferdinand Alexander founded his own industrial design company, Porsche Design, in Stuttgart, Germany, which was later moved to Zell am See, Austria, where the Porsche family owns an estate called Schüttgut. The first product Porsche Design created was a chronograph wristwatch made by Swiss watchmaker company Orfina. Its design started while F.A. was still working at the Porsche Style bureau. It was launched in 1973 and was different from other chronograph wristwatches, as its case and bracelet were made out of matte black chromed steel. It was intended as accessory for Porsche drivers and sold by the Porsche dealers. It operated the then-new Valjoux 7750 movement, which is today still the most widespread mechanical movement for chronograph wristwatches. As many customers would have liked a normally-coloured watch, a version with bead-blasted stainless steel was issued. Later the movement was changed to the Lemania 5100, which was a simple and rugged movement mainly used for military watches. The Porsche Design Chrono I was made in different versions — color of case and straps, print on dial — for several country's air forces, as well as the NATO alliance.
