THE HEART OF THE
COSMOGRAPH DAYTONA MODEL
OYSTER PERPETUAL
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.
