HERE ARE SOME OF THE EXCLUSIVE MATERIALS THAT GO INTO A ROLEX WATCH: OYSTERSTEEL : This is 904L grade steel, a superalloy used in the aerospace and chemical industries, and that means it has the corrosion resistance and high polish of precious metals. It also has a high sheen, so it looks good for a long time. EVEROSE GOLD: To preserve the beauty of its pink gold watches, in 2005 Rolex created and patented a new alloy that it casts in its own foundry: Everose gold, which owes its unique color — a pink hue unlike any other — to its composition. PLATINUM: Rolex uses 950 platinum, an alloy consisting of 95 percent pure platinum generally combined with ruthenium. At Rolex, platinum is above all used for the Day-Date, the most prestigious watch in the Oyster collection. The practiced eye immediately recognizes a Day-Date or Daytona with an ice blue dial as a platinum model.

ROLESOR: Rolesor is the story of the auspicious meeting of two materials on a single Rolex watch: the juxtaposition of gold and steel with their contrasting colors and radiance, in subtly balanced harmony. The name Rolesor was patented by Rolex in 1933, and has become one of the distinctive elements of the brand’s watches, a true Rolex signature. The bezel, winding crown, and center bracelet links are made of 18k yellow or Everose gold, and the middle case and the outer links of the bracelet are made of Oystersteel. CERACHROM: Developed and patented by Rolex, these components are made from particularly hard ceramics that are virtually impervious to scratches. Their colors are unaffected by ultraviolet rays. Thanks to its chemical composition, the high-tech ceramic cannot corrode. CHROMALIGHT: Rolex’s luminescent material, Chromalight is blue by night, bright white by day, providing high visibility in dark environments.
