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.
Towind the watch manually, unscrew the winding
crown completely, then turn it several times
clockwise. (Turning in the other direction has
noeffect.) A minimum of 25turns is required for
adequate partial winding.The watch will then
bewound 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

Daytona is the benchmark for those with
a passion for driving and speed. Of

of choice for measuring elapsed time
or calculating average speeds.

thanks to its Chromalight display
elements filled with a high-performance
luminescent material.

waterproof to a depth of 100 meters
(330feet), is a paragon of robustness and
reliability. ItsTriplock 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.The sapphire crystal

an anti-reflective coating.

is equipped with a self-winding mechanical
movement entirely manufactured by Rolex.
