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 suc-cessfully 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.

Fluted bezel
The Rolex fluted bezel is a mark of distinction. Originally, the fluting of the Oyster bezel had a functional purpose: it served to screw the bezel onto the case helping to ensure the waterproofness of the watch. It was therefore identical to the fluting on the case back, which was also screwed onto the case for waterproofness, using specific Rolex tools. Over time, the fluting became an aesthetic element, a genuine Rolex signature feature. Today the fluted bezel is a mark of distinction, in gold on this Datejust 31.
Mint green 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.
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
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 Retailers, who receive regular deliveries and independently manage the allocation and sales of watches to customers.
Swiss Time Square is proud to be part of the worldwide network of Official Rolex Retailers and can provide information on the availability of Rolex watches.
