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.
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.Model Availability
