Olive-Green Dial

This dial features diamonds in 18 ct gold settings. 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.

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.

18 ct Everose gold

To preserve the beauty of its pink gold watches, Rolex created and patented an
exclusive 18 ct pink gold alloy cast in its own foundry: Everose gold. Introduced
in 2005, 18 ct Everose is used on all Rolex Oyster models in pink gold.
