Maintenance service

Please note that as with any micromechanical pre-
cision instrument, HAMILTON watches require regular
maintenance. This keeps your watch in perfect work-
ing order and makes it last longer.
The frequency with which this maintenance work
needs to be carried out depends on the model, as
well as climatic conditions and the owner's care of
the watch. Therefore we cannot give a specific time
interval for servicing. We generally recommend that
a complete maintenance service should be carried
out every 3 to 5 years.
To ensure that the service is carried out professionally,
kindly take your watch to an authorized HAMILTON
Service Center or official HAMILTON retailer.
Water resistance
During the final check, HAMILTON watches are
checked for water-resistance as marked on the back
of the case, but the water-resistance of a watch is not
permanent. The water resistance of a watch can be
impaired by the natural aging process of the gaskets
(case back gasket, crown gasket, crystal gasket etc.)
or accidental knocks to the watch case.
Additionally, external influences like perspiration,
chlorine- or saltwater, ultraviolet rays and cosmetic
products can compromise the sealing over time.
Therefore, always rinse your watch with clear water,
when it comes in contact with chlorine- or saltwater.
Basic advice for safeguarding the water resistance
of your watch:
The water resistance should be checked once a year
by an authorized HAMILTON Service Center.
Please ensure that the crown, according to the
model, is pressed back into position 0, or screwed
back carefully so that water cannot get into the
mechanism.
Do not use crown/push button functions under water.

Leather straps
Please note that leather is a natural material subject
to natural ageing. Depending on your wearing habit,
the strap should be replaced regularly for reasons of
safety (security of the watch on your wrist), as well
as aesthetic and hygiene reasons. In normal, daily
wearing conditions it has an average life of six to
twelve months.
To keep your leather strap in good condition for
as long as possible, HAMILTON recommends the
following:
• Protect your leather strap from heavy and long
exposure to sunlight to prevent discoloration.
• Leather is permeable, contact with oily substances
and cosmetics can damage it.
• To prevent deformation and fading of color, avoid
contact with any kind of water.
• Clean your leather strap with a soft dry cloth, chem-
ical substances can damage it.
Bathing in the sea and swimming pools
Always rinse your watch with clear water after use in,
or contact with salt or chlorine water.
Cleaning
All HAMILTON watches can be cleaned with a soft,
dry cloth periodically. Water resistant watch cases,
bracelets and rubber straps can be cleaned by using
a small brush (e.g. a toothbrush) and soapy water.
Rinse it with clear water afterwards and use a soft
cloth to dry it.
Chemical products
Direct contact with solvents, detergents, perfumes,
cosmetic products etc. can damage your strap/
bracelet and case. Further, such chemical liquids
