The Oyster Perpetual Yacht-Master 40 in Oystersteel and platinum with an Oyster bracelet.

The Yacht-Master’s bidirectional rotatable 60-minute graduated bezel is made entirely from precious metals or fitted with a Cerachrom insert in high-tech ceramic. 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 Oystersteel, the bezel of the Rolesium versions is made of platinum, imparting a silvery whiteness and vibrant luminosity for an unmistakable sense of luxury.

The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology, designed to be both robust and comfortable. It is equipped with an Oysterlock folding clasp, which prevents accidental opening and the Easylink comfort extension link, also exclusive to Rolex.

This ingenious system allows the wearer to increase the bracelet length by approximately 5 mm, providing additional comfort in any circumstance.
