Mother-of-Pearl Dial

This dial features diamonds in 18 ct gold settings. Mother-of-pearl is by its nature full of mystery and surprises. Depending on its origin, it can be pink, white, black or yellow. It differs in colour, intensity and structure according to the part of the shell from which it is extracted. At Rolex, mother-of-pearl is never artificially coloured. Instead, particular know-how and skill are devoted to simply highlighting its natural beauty and preserving the original hues. As all mother-of-pearl dials are unique pieces, an identical dial will never be found on another wrist.

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.

Siam Swiss 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.
