White dial

Lacquer combines almost limitless freedom of colour with intensity and a smooth finish. The lacquering technique consists of successively depositing six thin layers of lacquer on a brass base plate. A colourless varnish is then applied to give the colour or shade all of its depth and shine. Once the varnish is dry, the surface of the dial is polished to magnify the colour; the dial is then ready to be pad printed and receive its appliques.

Yellow 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 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.
