BIDIRECTIONAL ROTATABLE BEZEL
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.
BLACK DIAL
Like all Rolex Professional watches, the Yacht-Master 42 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 WHITE GOLD
By operating its own exclusive foundry, Rolex has the unrivalled ability to cast the highest quality 18 ct gold alloys. According to the proportion of silver, copper, platinum or palladium added, different types of 18 ct gold are obtained: yellow, pink or white. They are made with only the purest metals and meticulously inspected in an in-house laboratory with state-of-the-art equipment, before the gold is formed and shaped with the same painstaking attention to quality. Rolex's commitment to excellence begins at the source.
