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.
