Intense black dial
Like all Rolex Professional watches, the Yacht-Master 40 offers exceptional legibility in all circumstances, and especially in the dark, thanks to its Chromalight display. The broad hands and hour markers in simple shapes – triangles, circles, rectangles – are filled with a luminescent material emitting a long-lasting glow.


18 CT EVEROSE GOLD
To preserve the beauty of its pink gold watches, Rolex created and patented an exclusive 18 ct pink gold alloy cast in its own foundry: Everose gold. Introduced in 2005, 18 ct Everose is used on all Rolex Oyster models in pink gold.
