Rolex Datejust 31 in Oystersteel and yellow gold features a white dial

This Oyster Perpetual Datejust 31 in Oystersteel and yellow gold features a white dial and a Jubilee bracelet.

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.

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 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.
