18 ct yellow gold and 18 ct Everose gold
A unique shine
Unique in the watchmaking world, Rolex has chosen to be in complete control of the creation, casting and shaping of its 18 ct gold alloys by installing its own foundry.
This allows the brand to produce gold alloys of the highest quality, notable for their exceptional purity and shine. 18 ct gold, an alloy eminently suitable for watchmaking, is composed of 750 ‰ (thousandths) of pure gold. According to the proportion of silver, copper or other elements added, different types of gold are obtained: yellow gold, white gold or Everose gold, the patented pink gold alloy developed by Rolex.
