Rolex
Datejust 31
Oyster, 31 mm, Oystersteel, yellow gold and diamonds

To ensure the precision and reliability of its timepieces, Rolex submits each watch after assembly to a stringent series of tests. All new Rolex watches purchased from one of the brand’s Official Retailers come with a five-year international guarantee. When you buy a Rolex, the Official Retailer fills out and dates the Rolex guarantee card that certifies your watch’s authenticity.
The five-year guarantee which applies to all Rolex models is coupled with the green seal, a symbol of its status as a Superlative Chronometer. This exclusive designation attests that the watch has successfully undergone a series of specific final controls by Rolex in its own laboratories according to its own criteria, in addition to the official COSC certification of its movement.
Every Rolex is delivered in a beautiful green presentation box that is both protector and keeper of the jewel that nests inside it. As the presentation box is also a symbol of giving, it is important, if you are purchasing a gift, that the recipient’s first contact with their Rolex sets the stage for revealing what lies within.

Gem setting
Large VI set with 11 diamonds
Olive-Green 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.

Yellow 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
All Rolex watches are assembled by hand with extreme care to meet the brand's high quality standards. Such a level of requirement naturally restricts Rolex's production capacities.
This is why the availability of certain Rolex models may be limited. New Rolex watches are available exclusively from official retailers, who are regularly stocked and independently manage the allocation of watches to customers.
Cooke & Kelvey has the honor of being part of the global network of official Rolex retailers and will be able to inform you about the availability of the different models.
