Diamond-Set BezelGem-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.

Yellow RolesorGold 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.


All Rolex watches are assembled by hand with the utmost care to ensure exceptional quality. Such high standards naturally restrict Rolex production capacity and, at times, the demand for Rolex watches outpaces this capacity.
Therefore, the availability of certain models may be limited. New Rolex watches are exclusively sold by Official Rolex Jewelers, who receive regular deliveries and independently manage the allocation and sales of watches to customers.
C.D.Peacock is proud to be part of the worldwide network of Official Rolex Jewelers and can provide information on the availability of Rolex watches.
Rolex’s classic feminine watch, the Lady-Datejust is in the lineage of the Datejust, the emblematic model that has been a byword for style and accurate timekeeping since its launch in 1945. The first women’s version of this date chronometer, the Lady-Datejust, appeared in the late 1950s, bringing the heritage of timeless elegance and functionality to a smaller size perfectly suited to a lady’s wrist.
