18 ct 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.

White Carousel Dial

Mother-of-pearl is by its nature full of mystery and surprises. Depending on its origin, it can be pink, white, black or yellow. It differs in colour, intensity and structure according to the part of the shell from which it is extracted. At Rolex, mother-of-pearl is never artificially coloured. Instead, particular know-how and skill are devoted to simply highlighting its natural beauty and preserving the original hues. As all mother-of-pearl dials are unique pieces, an identical dial will never be found on another wrist.

The President bracelet

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.

3155 Movement

The Day-Date 36 is equipped with calibre 3155, a self-winding mechanical movement entirely developed and manufactured by Rolex. It features a day and date calendar disc mechanism. Like all Rolex Perpetual movements, the 3155 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.
