Fluted bezel

The Rolex fluted bezel is a mark of distinction. Originally, the fluting of the Oyster
bezel had a functional purpose: it served to screw the bezel onto the case helping
to ensure the waterproofness of the watch. It was therefore identical to the fluting
on the case back, which was also screwed onto the case for waterproofness, using
specific Rolex tools. Over time, the fluting became an aesthetic element, a genuine
Rolex signature feature. Today the fluted bezel is a mark of distinction, in gold on
this Lady-Datejust.

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.

White 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.
