HOW HARD IS HARD?
The hardness of Rado high-tech materials
guarantees durability and brilliance. The
Vickers scale is used to indicate hardness:
the higher a value, the greater the
resistance.
The value of 10,000 is attributed only
to natural diamonds and to the Rado high-
tech diamond surface.
NOTE: Rado watches are hard but not
indestructible. Although our high-tech
materials are resistant, Rado watches must
be treated with care. They should not be
dropped, and sharp knocks should be
avoided. If hit hard enough, the materials
may break.
PRECIOUS STONES
The name “Jubilé” refers to all the Rado
products with diamonds or other precious
stones. Depending on the model, the name
“Jubilé” may or may not figure on the dial.
Details regarding the precious stones used
on Jubilé watches may be found
on the accompanying Precious Stone
Certificate.
The quality of a diamond is defined by 4C’s:
Carat, Clarity, Color and Cut.
CARAT
The weight of a diamond is measured
in carats. 1 carat is the equivalent
of 0.2 grams.
Stones of various weight classes and sizes
are used in Rado “Jubilé” models.
CLARITY
The diamond clarity rating of stones used by
Rado is generally VVS (Very Very Small
Inclusions) on the case and VS-SI (Very
Small - Small Inclusions) on the dial.
