What Are Rolex Watches Made Of?

Rolex doesn't just assemble watches — they manufacture nearly everything in-house, including their own metal alloys. Here's what goes into every piece.

904L Oystersteel

While most watchmakers use 316L stainless steel, Rolex exclusively uses 904L — a superalloy originally developed for the chemical industry. It's more corrosion-resistant, harder to machine, and takes a higher polish. It's also why Rolex steel watches feel different on the wrist.

Everose Gold

Rolex's proprietary rose gold alloy, patented in 2005. It adds platinum to the gold-copper mix, which prevents the copper from oxidizing over time. Standard rose gold can fade — Everose won't.

Cerachrom Bezels

The colored bezels on modern Submariners, GMT-Masters, and Daytona are made from ceramic — specifically, Rolex's proprietary Cerachrom material. It's scratch-proof, UV-resistant, and the color is integral to the material (not a coating that can chip).

Sapphire Crystal

Every modern Rolex is fitted with synthetic sapphire crystal — 9 on the Mohs hardness scale (only diamond is harder). Rolex manufactures these in-house at their Plan-les-Ouates facility.

Chromalight & Lume

Rolex developed Chromalight, a blue-glowing luminescent material that lasts twice as long as standard lume. You'll find it on all modern sport models.
