904L STAINLESS STEEL
Performance fit for extremes
A Rolex watch must remain functional and maintain its beauty even in the harshest environments. That is why Rolex became, in 1985, the first watchmaking brand to use 904L steel, a highly corrosion-resistant superalloy that acquires an exceptional sheen when polished.
904L stainless steel is commonly used in high-technology and in

The source of the shine
Gold Rolex watches possess a truly captivating radiance, born of years of experience in perfecting the use of this most precious of metals. Only by controlling the whole process can Rolex guarantee a peerless, enchanting lustre on its watchcases and bracelets alike.
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, copper, platinum and palladium necessary to produce the different types of 18 ct gold: yellow, Everose and white. Rolex’s jealously-guarded formulas ensure exceptional durability, polishability – and an extraordinary sheen that lasts for generations.

Rare and precious, considered the noblest of metals, platinum is striking for its silvery whiteness and its vibrant luminosity. Over time it has become the ultimate metal of prestige, with the ability to showcase precious stones like no other material.
Rolex uses 950 platinum, an alloy consisting of 950‰ (thousandths) platinum generally combined with ruthenium. This allows the metal to be robust enough to be used in watch cases, while maintaining its legendary shine and brilliance.
