Special recommendations
What must I do to ensure that my OMEGA watch provides me with excellent service for many years?
Magnetic fields: avoid placing your watch on loudspeakers or refrigerators, since they generate powerful magnetic fields.
Swimming in the sea: always rinse your watch with warm
water afterwards.
Shocks: whether thermal or other, avoid them.
Screw-in crown: screw in the crown carefully to prevent
water from penetrating the mechanism.
Non screw-in crown: push it back into the neutral position
to prevent water from entering the mechanism.
Cleaning: for metal bracelets and water-resistant cases,
use a toothbrush with soapy water to clean and a soft
cloth for drying.
Chemical products: avoid direct contact with solvents,
detergents, perfumes, cosmetics etc., since they may
damage the bracelet, case or gaskets.
Temperature: avoid exposure to extreme temperatures
(greater than 60°C, or 140°F, less than 0°, or 32°F) or
extreme temperature changes.
Water resistance: a watch's water resistance cannot be
permanently guaranteed. It may be affected by ageing
of gaskets or by an accidental shock to the crown. As
stipulated in our service instructions, we recommend you
have the water resistance of your watch checked once a
year by an approved OMEGA service agent.
Chronograph push-pieces: Do not operate chronograph
pushers under water in order to prevent water entering
the mechanism.
Exception: The Seamaster 300 m Chronographs have
pushers which can function under water.
What are the service intervals?
Like any precision instrument, a watch needs regular
servicing to ensure that it functions perfectly. We cannot
indicate the frequency of such work, since it depends

Used batteries, watch components and electronic watches
should not be thrown away. They should be recycled
correctly. We recommend you return them to your nearest
OMEGA retailer.
OMEGA recommends that you follow the steps below in
order to preserve the condition of your leather strap for as
long as possible:
•
Avoid contact with water and dampness to prevent
discoloration and deformation.
•
Avoid prolonged exposure to sunlight to prevent the
colour from fading.
•
Do not forget that leather is permeable! Therefore
avoid contact with greasy substances and cosmetic
products.
•
If you have a problem with your leather strap, please
contact your nearest OMEGA retailer.

entirely on the model, the climate and the owner's individual care of the watch. As a general rule, a watch should
be serviced every 4 to 5 years, depending on the conditions in which it is used.
Who should I contact for a maintenance service or
battery replacement?
We recommend that you contact an approved OMEGA service centre or authorised OMEGA retailer, who are the only
entities equipped with the tools and apparatus required
to carry out the work and the necessary checks in a professional manner. Furthermore, only these entities can
guarantee that their work is carried out in accordance
with OMEGA's strict quality standards.

Anti-reflective treatment
t
Screw-in crown
The anti-reflective treatment on both sides of the sapphire
crystal improves the visibility of your watch’s dial. Wear
and tear may cause marks to appear. These are considered
normal and are therefore not covered by the warranty.
Some watches are fitted with a screw-in crown which
should be unscrewed before use. After use, push the crown
into position 1 then press and screw back in (water-resistance).
