Case Fabrication and Finishing

Rolex cases are crafted from high-quality materials such as Oystersteel (a proprietary 904L stainless steel), 18k gold alloys, or platinum. The fabrication process involves several stages to achieve the brand’s signature robustness and aesthetic appeal.

The initial step is machining the case components with CNC (Computer Numerical Control) machines, which carve out precise shapes from solid blocks of metal. This is followed by a meticulous hand-finishing process, where skilled artisans polish and brush surfaces to create the desired textures and finishes. The polishing phase enhances not only the visual appeal but also the corrosion resistance of the metal.

Additionally, Rolex employs advanced techniques such as:

  • Cerachrom bezel inserts: Made from an extremely hard ceramic material, these bezels are scratch-resistant and maintain color integrity over time.
  • Sapphire crystal fitting: Synthetic sapphire crystals are cut and polished to fit snugly within the case, providing superior scratch resistance and clarity.

Dial Creation and Detailing

The dial is the watch’s visual centerpiece, and Rolex invests heavily in its design and production. Dials begin as blank metal discs, which are then coated and decorated through multiple processes to achieve the exact color, texture, and luminosity.
