The Yacht-Master’s bidirectional rotatable 60-minute graduated bezel is made of precious materials. The raised polished numerals and graduations stand out clearly against a matt, sand-blasted background. This functional bezel – which allows the wearer to calculate, for example, the sailing time between two buoys – is also a key component in the model’s distinctive visual identity.
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.
Many Rolex watches are available with the now-legendary combination of yellow, white or Everose gold and steel known as Rolesor, but Rolesium is a creation specific to the Yacht-Master. While the case and bracelet are in rugged 904L stainless steel, the bezel of the Rolesium versions is made of 950 platinum, imparting a silvery whiteness and vibrant luminosity for an unmistakable sense of luxury.
