What can I do to ensure that my LONGINES
watch functions perfectly for many years?
Magnetic fields: avoid putting your watch on a loud-
speaker or on a refrigerator because these machines
create magnetic fields that may damage it.
Salt-water: always rinse your watch in fresh water after
swimming in the sea.
Shocks: avoid subjecting your watch to shocks, includ-
ing sudden changes in temperature.
Screw-in crown: always make sure you have screwed
the crown in fully to avoid any humidity getting into the
mechanism.
Push-in crown: always push the crown back in to the
neutral position to avoid any humidity getting into the
mechanism.
Cleaning: use a toothbrush and soapy water to clean
metal bracelets and water-resistant cases and a soft
cloth to dry off afterwards.
Chemical products: avoid all direct contact with sol-
vents, detergents, perfume, cosmetics, etc. which may
damage the bracelet or strap, the case or the seals.
Temperatures: avoid exposing your watch to extreme
temperatures (over 60 ° C or 140 ° F and under 0 ° C
or 32 ° F) and to sudden fluctuations in temperature.
Water-resistance: we cannot guarantee that your
watch will be permanently water-resistant. The seal
may be affected by wear or by an accidental shock to
the crown. As recommended in our service instructions,
you should have the water-resistant seals of your watch
tested once a year by an approved LONGINES agent.
Chronograph push-pieces: do not adjust the push-
pieces under water as this may allow humidity to get
into the mechanism.
TOLERANCES / WINDING
Mechanical movements
The precision of a mechanical movement varies depend-
ing on the wearer’s habits. The majority of LONGINES
watches have a precision of between – 5 and +15 seconds
per day.
Winding (crown pushed right in)
The natural movements of your wrist will automatically
wind your Longines watch, which has a power reserve
of several dozen hours (see table of equivalents on
p. 50-51). It is only necessary to wind it manually if your
watch/chronograph has not been worn for several days.
Occasional winding:
if your watch has not been
worn for one day or more, wind it manually with the
crown in position 1.
