The Rolex crown, the logo and symbol par excellence of the brand, was registered in 1931. Pioneer in the development of the wristwatch, Rolex is at the origin of numerous major watchmaking innovations, and has registered over 500 patents in the course of its history. The history of Rolex and Swiss watchmaking are inextricably linked. Here, 18 ct yellow, white or Everose gold are created, cast and formed in accordance with the strictest quality criteria in order to ensure a peerless, handsome lustre for Rolex watch cases and bracelets. It can be ascribed to the absolute purity of the exclusive alloys that Rolex creates in its own foundry by melting noble metals at over 1,000 ☌. The radiance of the gold used for Rolex watches comes from art not chance. With a formula protected by several patents, Everose gold illustrates the level of care that Rolex places on developing materials that correspond to its exacting aesthetic and quality requirements. Introduced in 2005, 18 ct Everose is used on all Rolex models in pink gold. To preserve the beauty of its pink gold watches, Rolex created and patented an exclusive 18 ct pink gold alloy cast in its own foundry: Everose gold.

Jealously-guarded formulas ensure exceptional durability, polishability – and an extraordinary sheen that lasts for generations. Rolex exclusively uses 18 ct gold, a princely alloy composed of 750‰ (thousandths) of pure gold, plus exactly the right mixture of elements including silver and copper necessary to produce the different types of 18 ct gold: yellow, white and Everose, Rolex's exclusive pink gold alloy.

Gold Rolex watches possess a truly captivating radiance, born of years of experience in perfecting the use of this most precious of metals. Oystersteel is extremely resistant, offers an exceptional finish once polished and maintains its beauty even in the harshest environments. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential. Rolex uses Oystersteel for its steel watch cases. On white Rolesor models, the bezel alone is in white gold. The concept is simple: the bezel, the winding crown and the centre bracelet links are made of yellow or Everose gold (Rolex’s exclusive pink gold alloy) the middle case and the outer links of the bracelet are made of Oystersteel. The name Rolesor was patented by Rolex in 1933 and has become a true Rolex signature. Rolesor is the auspicious meeting of two metals on a single Rolex watch: gold and steel, with their contrasting colours and radiance, in subtly balanced harmony.
