Dark Grey Dial

This dial features a large VI set with 11 diamonds. 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.

White Rolesor

Gold is coveted for its lustre and nobility. Steel reinforces strength and reliability.
Together, they harmoniously combine the best of their properties. A true Rolex
signature, Rolesor has featured on Rolex models since the early 1930s, and was
trademarked as a name in 1933. It is one of the prominent pillars of the Oyster
collection.
