GOLD (YELLOW, WHITE AND EVEROSE)
Since the early 2000s, Rolex has also been producing the gold used in their watches. They exclusively use 18k gold, plus exactly the right mixture of elements, such as silver and copper, to produce 18k yellow, white, and rose gold. The exclusive Everose gold has a mix of platinum, which holds color for years, even when exposed to saltwater or sunlight.
Rolex uses 950 platinum, an alloy consisting of 950 thousandths of platinum combined with ruthenium, a chemical element in the platinum group. This combination makes their platinum alloy robust enough to be used for watches, while maintaining its brilliance and shine.
