Rolex Guarantee

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 green seal

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.

Rolex presentation box

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.

Slate Dial

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.

Everose 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.

The Jubilee bracelet

The design, development and production of Rolex bracelets and clasps, as well as the stringent tests they face, involve advanced high technology. And, as with all the components of the watch, aesthetic controls by the human eye guarantee impeccable beauty. The Jubilee, a supple and comfortable five-piece link metal bracelet, was designed and made especially for the launch of the Oyster Perpetual Datejust in 1945.

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.
