Rolex Day-Date 36mm in yellow gold features a black dial

The Oyster Perpetual Day-Date 36 in 18 ct yellow gold with a black dial, domed bezel and a President bracelet.

Each dial is a miniature work of art. A meeting of traditional skills and technology, the manufacture of Rolex dials perfectly encapsulates the philosophy that guides the brand: seeking the
highest level of quality to achieve an impeccable, long-lasting result.

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. The design, development and production of Rolex bracelets and clasps, as well as the stringent tests they face, involve advanced high technology. And, as with all the components of the watch, aesthetic controls by the human eye guarantee impeccable beauty. The President bracelet, with its semi-circular three piece links, was created in 1956 for the launch of the Oyster Perpetual Day-Date. It represents the ultimate in refinement and comfort and is always made of carefully selected precious metals.
