CHRONOMETER CERTIFICATE C.O.S.C.
Each timepiece is numbered and equipped with a Chronometer
Certificate awarded by the Swiss Official Chronometer Control to
certify the reliability of this exceptional timepiece.
PRECISION
Precision and average daily rate depend on the activity of the per-
son wearing the instrument. Magnetic fields (computers, mobile
phones, etc.)may influence the working of a watch. Violent shocks
or knocks - quite common in tennis or golf − should be avoided to
prevent shaking that may loosen certain parts.
MAINTENANCE
All mechanical watches should have their movements cleaned and
the oil replaced every 3-5 years. The life span of any mechanical
timepiece will primarily depend upon both daily care and the
recommended routine maintenance. We strongly encourage
you to have your timepiece serviced only at officially authorized
Ulysse Nardin Customer Service Centers. For additional infor-
mation regarding Customer Service please visit our website :
