This dial features hour markers in 18 ct gold, set with 32 diamonds, and a Roman VI and IX in 18 ct gold, set with 24 diamonds. It is cut from green aventurine, a stone with a finely crystallized surface.The dial is the distinctive face of a Rolex watch, the feature most responsible for its identity and readability. Characterised by hour markers fashioned from gold to prevent tarnishing, every Rolex dial is designed and manufactured in-house, largely by hand to ensure perfection.
