Description

This Oyster Perpetual
Cosmograph Daytona in
18 kt white gold, with a
black and white motherof-pearl, diamond-set
dial and an Oyster
bracelet, features a
diamond-set bezel.
Mother-of-Pearl Dial
A unique effect
The contrasting dial is made from natural motherof-pearl and graced with eight diamonds and three
Chromalight hour markers. The strength of the
contrast, the intensity of the colours and the depth
of the reflections are the result of a particularly
stringent material selection process. Both varieties
of mother-of-pearl are handled with the greatest
care by the brand’s artisans.
The dial allows drivers to accurately map out their
track times and tactics without fail.
Diamond-set bezel
Adorning a legendary
chronograph
The timepiece incorporates a bezel adorned with
36 brilliant-cut diamonds.
This now legendary chronograph is the instrument
of choice for measuring time intervals and
determining average speeds. On this gem-set
version, the emblematic tachymetric scale is
replaced with diamonds.
18 kt white gold
Commitment to
excellence
By operating its own exclusive foundry, Rolex has
the unrivalled ability to cast the highest quality 18
kt gold alloys. According to the proportion
of silver, copper, platinum or palladium added,
different types of 18 kt gold are obtained: yellow,
pink or white.
They are made with only the purest metals and
meticulously inspected in an in-house laboratory
with state-of-the-art equipment, before the gold is
formed and shaped with the same painstaking
attention to quality. Rolex’s commitment to
excellence begins at the source.
The Oyster bracelet
Alchemy of form and
function
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 Oyster bracelet is a perfect alchemy of form
and function. First introduced in the late 1930s,
this particularly robust and comfortable metal
bracelet with its broad, flat three-piece links
remains the most universal bracelet in the Oyster
collection.
