COSMOGRAPH DAYTONA
OYSTER PERPETUAL
WEARING THE WATCH
FOR THE FIRST TIME
Before being worn for the first time, or if it has
stopped, a Rolex watch must be wound manually
in order to function correctly and precisely.
Towind the watch manually, unscrew the winding
crown completely, then turn it several times
clockwise. (Turning in the other direction has
noeffect.) A minimum of 25turns is required for
adequate partial winding. The watch will then
bewound automatically as long as it is worn on
the wrist. Carefully screw the crown back down
against the case to ensure waterproofness.
The green seal accompanying your
Rolex watch is a symbol of its status
as a Superlative Chronometer. This
exclusive designation attests that it
has successfully undergone a series of
specific final controls by Rolex in its own
laboratories in addition to the official
COSC certification of its movement.
This unique testing of its chronometric
precision, waterproofness, self-winding
and reliability pushes back the
boundaries of performance and makes
Rolex a benchmark for excellence
in mechanical watches. For further

COSMOGRAPH DAYTONA
The Oyster Perpetual Cosmograph
Daytona is the benchmark for those with
a passion for driving and speed. Of
legendary relia bility, this model features
a centre chronograph seconds hand,
30-minute and 12-hour counters and
a tachymetric bezel, making it the
instrument of choice for measuring
elapsed time and calculating average
speeds.
The dial offers exceptional legibility
thanks to its Chromalight display
elements filled with a high-performance
luminescent material.
Its 40 mm Oyster case, guaranteed
waterproof to a depth of 100 metres
(330feet), is a paragon of robustness
and reliability. Its Triplock winding crown,
with a triple waterproofness system, is
protected by a crown guard crafted as an
integral part of the middle case. Both
the winding crown and the chronograph
pushers screw down against the case. Its
sapphire crystal is virtually scratchproof.
The Oyster Perpetual Cosmograph
Daytona is equipped with a self-winding
mechanical movement entirely
manufactured by Rolex.

CARING FOR

cleaning it occasionally with a microfibre
cloth. You can also wash the case and
bracelet from time to time using soapy
water and a soft brush. After wearing
your watch in the sea, it is important to
rinse it with fresh water to remove any
salt and sand deposits.

AFTER-SALES
SERVICE
Rolex watch servicing ensures that
your timepiece will continue to
perform optimally and meet Rolex’s
stringent requirements in terms of
precision, reliability and waterproofness
throughout its life.
The timekeeping accuracy of your watch
is largely dependent on high-performance
lubricants specially developed by Rolex
to minimize friction and prevent wear
of components. To guarantee continued
accuracy and waterproofness, Rolex
recommends that you periodically return
your watch to an Official Rolex Retailer or
Service Centre for professional servicing.
When your watch is serviced by a Rolex
watchmaker, the watch is completely
dismantled and all of its components
are cleaned. Each individual component
is closely examined and those that
nolonger meet Rolex’s functional and
aesthetic specifications are replaced
with genuine Rolex parts.
The movement is carefully lubricated
then tested to guarantee its timing
accuracy; the case and the metal bracelet
are meticulously refinished to restore
19
their lustre. Your Rolex then undergoes
a series of rigorous technical tests and
checks to guarantee its waterproofness,
power reserve and precision.
After a complete Rolex service, your
watch is covered by a service guarantee.
