SKIN-FRIENDLINESS
For Rado, luxury means not only aesthetic
perfection and the choice of exquisite mat-
erials but also personal comfort. Apart from
ensuring durability, our high-tech materials
ensure that Rado watches are gentle to the
skin and smooth on the wrist.
SWISS PRECISION
The name Rado guarantees a Swiss quality
watch movement of the greatest precision.
Every movement undergoes numerous con-
trols before being installed in a Rado watch.
The average deviation of a Rado quartz
watch should not exceed 15 seconds per
month. The average deviation of a Rado
automatic watch should not exceed -5 to
+20 seconds per day.
RADO CHRONOMETERS
All Rado chronometers are equipped with
first-class Swiss chronometer movements
known for their ultra-precise accuracy. Each
movement is rigorously tested and certified
by the Official Swiss Chronometer Testing
Institute (Contrôle Officiel Suisse des
Chronomètres, COSC). This neutral and
independent body individually tests each
movement for 360 consecutive hours,
during which it is placed in the five common
wrist positions and exposed to three
different temperatures. To earn the title
of chronometer, the mechanical movement’s
average variation in rate must be between
-4/+6 seconds per day, or a precision
of 99.99% – the highest precision attainable
by a mechanical movement. A special
certificate accompanies all COSC-certified
movements.
