CLEANING AND MAINTENANCE

CLEANING
To clean the outer surface of the watch, wipe
it gently with a microfiber cloth. Use a fine
toothbrush and a bit of soapy solution to
clean the back of the watch and the metal
band. Dry using a lint-free towel. Minimize
contact between the leather straps and the
water.
MAINTENANCE
As a mechanical instrument, a watch
requires maintenance by an authorized
service center about once every four years.
WATER RESISTANCE
A watch tested to 3 atm (30 m) is resistant to
sweat, drops of water and rain. Water resis-
tance is guaranteed only if the crown is in
the initial position and should be checked
once per year.
