Rosé-colour dial

This dial features diamonds in 18 ct gold settings. The sunray finish creates delicate
light reflections on many dials in the Oyster Perpetual collection. It is obtained using
masterful brushing techniques that create grooves running outwards from the centre
of the dial. Light is diffused consistently along each engraving, creating a characteristic
subtle glow that moves depending on the position of the wrist. Once the sunray finish
has been completed, the dial colour is applied using Physical Vapour Deposition or
electroplating. A light coat of varnish gives the dial its final look.

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.
