Ideal accomplishments
The Oyster Perpetual Day-Date 40 in 18 ct Everose gold, with a white mother-of-pearl, diamond-set dial, diamond-set bezel and a President bracelet.
Mother-of-Pearl Dial
Highlighting natural beauty
This dial features 10 baguette-cut diamonds. 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.
Diamond-set bezel
A sparkling symphony
Gem-setters, like sculptors, finely carve the precious metal to hand-shape the seat in which each gemstone will be perfectly lodged. With the art and craft of a jeweller, the stone is placed and meticulously aligned with the others, then firmly secured in its gold or platinum setting.
Besides the intrinsic quality of the stones, several other criteria contribute to the beauty of Rolex gem-setting: the precise alignment of the height of the gems, their orientation and position, the regularity, strength and proportions of the setting as well as the intricate finishing of the metalwork. A sparkling symphony to enhance the watch and enchant the wearer.
18 ct Everose gold
An exclusive patent
To preserve the beauty of its pink gold watches, Rolex created and patented an exclusive 18 ct pink gold alloy cast in its own foundry: Everose gold.
Introduced in 2005, 18 ct Everose is used on all Rolex Oyster models in pink gold.
The President bracelet
The ultimate refinement
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.
