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 yellow 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.
