Rose-colour dial
This dial features diamonds in 18 ct gold settings. 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.
18 ct Everose gold
To preserve the beauty of its pink gold watches, Rolex created and patented an exclusive 18 ct pink gold alloy cast in its own foundry: Everose gold. Introduced in 2005, 18 ct Everose is used on all Rolex Oyster models in pink gold.
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.
Official Rolex Retailer’s name] is proud to be part of the worldwide network of Official Rolex Retailers and can provide information on the availability of Rolex watches.
HOW TO SET YOUR DATEJUST 31
Synonymous with excellence and reliability, Rolex watches are designed for everyday wear, and depending on the model, perfectly suited for a wide range of sports and other activities. Built to last, these timepieces are characterized by their distinctive and timeless aesthetics. The Oyster Perpetual Datejust 31 is the expression of everlasting appeal. Learn more about this watch and how to set the time and date by watching the video.
Any day can leave a lasting mark on our lives and set the stage for new aspirations. Since its creation in 1945, the Datejust has continued to reinvent itself while symbolizing Rolex’s definition of classic elegance. A milestone in watchmaking history, it was the first self-winding waterproof chronometer wristwatch to feature a window displaying the date. Magnified by the Cyclops lens, these numbers are a reminder that though 24 hours mark a day, it’s on us to make those a date to remember.
