Mother-of-Pearl Dial

This dial features diamonds in 18 ct gold settings. 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

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

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.
