Dark Grey 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.

Oystersteel

Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential. Oystersteel is extremely resistant, offers an exceptional finish once polished and maintains its beauty even in the harshest environments.

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 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.

Srichai Watch 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 esthetics. 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.

The Oyster Perpetual Datejust is the archetype of the classic watch thanks to functions and aesthetics that never go out of fashion. This year, Rolex presents the Datejust 36 featuring new ‘palm’ and ‘fluted’ dial motifs. The palm motif evokes lush, vibrant tropical forests, while the fluted motif showcases the pattern found on a range of Rolex bezels that has become one of the brand’s signature aesthetic styles.
