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

English
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.
Environmental protection
Leather straps
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).

Perpetual calendar
CALIBRE 1680 (fig. V)
The particularity of the Gregorian calendar is that one
day (29th February) is added to the year every four years
to compensate for the length of the solar year, which is
365.242192 days, or almost 365 1/4 days. Such years are
called leap years and their number (e.g. 1996) is divisible by 4.
As the compensation of one day every four years is too
much, every 100 years (2100, 2200, …) the year is not a
leap year, even though it is divisible by four. However, even
this is not totally sufficient, since it leaves an error of one
day every 400 years. Therefore, if the number of the year is
divisible by 400 it is a leap year, as was the case with the
year 2000. Because of this, the perpetual calendar of your
watch is set to function correctly until 2100.
Thermocompensation
This movement is 10 times more precise than a conventional quartz movement thanks to an electronic module
that compensates for the effects of temperature on the
movement’s operation.
The crown has 3 positions:
Watch functions:
1.1. Neutral position 1, normal when the watch is worn:
in this position, the crown ensures that the watch is
water-resistant.
1.2. Setting the hands: minutes and seconds.
Pull the crown out to position 3 when the second
hand is at 12 o’clock. The seconds hand will stop.
Turn the crown forwards or backwards to set the
minute hand.
Push the crown back into position 1 to coincide with
a given time.
NOTE: To avoid inadvertently changing the date when
setting the time, it is important to always follow point
1.2 and then point 1.3.
26
1.3. Setting the date and hour hands:
Pull the crown out to position 2.
Then turn the crown: the hand moves in 1-hour
jumps. If it is necessary to correct the date, (A),
continue to turn the crown and the date will change
automatically when switching from AM to PM, or the
contrary, depending on the direction the crown is
turned. Then push the crown back to position 1.
Important:
When setting the date, it is essential to check the
date. If need be, pass midday (no date change) or
midnight (date changes) to make sure the time is set
in AM or PM as appropriate.
NB: Corrections in position 3 have no effect on
the date, even if the hour hand passes midday or
midnight. The watch stores the date in its memory (including whether AM or PM) before the time
is reset. Setting the hours, minutes and seconds,
around midnight and midday may therefore result in
the calendar shifting by 12 hours.
2. Checking and correcting the calendar:
month, yearly cycle and date.
2.1. Display and correction of the month.
Press and hold the crown in position 0 for more than
3 seconds, the month will be displayed for 8 seconds,
(B). 1 = January, 2 = February, ..., 12 = December.
The month can be corrected during these 8 seconds.
Pull the crown out to position 2, turn the hour hand
through one full revolution. The month will move
forwards or backwards.
Repeat the procedure until the required month is
displayed, then put the crown back to position 1.
Perpetual calendar
27
English
2.2. Display and correction of the yearly cycle.
Following display of the month (cf. 2.1.), the calendar
continues to function and the year cycle is displayed
in Roman numerals for 8 seconds, (C).
I = leap year +1 Example: 2005, 2009, 2013
II = leap year +2 Example: 2006, 2010, 2014
III = leap year +3 Example: 2007, 2011, 2015
IV = leap year Example: 2004, 2008, 2012
During these eight seconds, you can adjust the year
cycle. To do so, pull the crown out to position 2,
turn the hour hand through one full revolution. The
year cycle will move forwards or backwards.
Repeat the procedure until the required yearly cycle
is displayed. Push the crown back to position 1.
The calendar continues to function and displays the
date, A.
See point 1.3. for how to correct the date.
2.3. Changing the time zone or daylight saving time:
Pull the crown out to position 2 and turn it. Only the
hour hand will move forwards or backwards, without
affecting the minutes or seconds. Push the crown
back to position 1.
NOTE:
The end of battery life is indicated by the seconds hand
making 4-second jumps. The watch will continue to function for several days, but the battery must be removed
and replaced by an authorised OMEGA service agent as
soon as possible. Once the watch stops, a memory function stores the date for one month.

People travelling East, for example from London to Hong
Kong, should pull the crown out to position 2 and move
the hour hand forwards (in this case by 8 hours). The table
above can be used to calculate any time difference.
People travelling West, for example from London to New
York, should pull the crown out to position 2 and move the
hour hand backwards (in this case by 5 hours). The table
above can be used to calculate any time difference.
In both cases, the “24-hour” hand allows travellers to
read the time back home – London, in our example – at
a glance, using the 24-hour scale on the dial. The second
time zone – in this case Hong Kong or New York – is read
off the dial in the usual way.
Each time the hour hand crosses midnight, the date jumps
forwards or backwards, depending on whether the hour
hand is moved forwards or backwards.
CALIBRES 1128 (fig. VI) • 2628 (fig. VII)
• 3603 (fig. XX)
The crown has 3 positions:
1. Normal position (wearing position): when pushed
into the case, the crown ensures that the watch is
water-resistant.

Occasional winding: if the watch has not been worn
for 44 hours (cal. 1128, 2628) or 55 hours (cal. 3603)
or more, wind it up with the crown in position 1.
2. Setting the time zone: pull the crown out to position
2 and turn it. Only the hour hand moves (clockwise or
anticlockwise), without affecting the precision of the
minutes or seconds. If the hand moves past midnight,
the date changes automatically. Push the crown back
to position 1.
Setting the date: pull the crown out to position 2, turn
it forwards or backwards to change the date each time
the hour hand passes midnight. The date moves forwards
(or backwards) one day. Repeat until the required date is
obtained. Push the crown back to position 1
.
Synchronisation of the hour hand and the
“24-hour” hand (calibre 1128, fig. VI)
The triangle on the rotating bezel must point to
12 o’clock on the dial.
Pull the crown out to position 2 and turn it to syn-
chronise the hour hand with the time indicated by the
“24-hour” hand on the 24-hour scale on the rotating
bezel. Make sure you set the hour hand in the correct
half of the day! Push the crown back to position 1.
Synchronisation of the hour hand and the
“24-hour” hand (calibre 2628, fig. VII,
calibre 3603, fig. XX)
Pull the crown out to position 2 and turn it to syn-
chronise the hour hand with the time indicated by the
“24-hour” hand on the 24-hour scale in the centre of
the dial. Make sure you set the hour hand in the correct half of the day!
After synchronising the hour hand with the “24-hour”
hand, you must set the local time on your watch. Push
the crown back to position 1.

3. Setting the time: hours – minutes – seconds. Pull
the crown to position 3. The seconds hand will stop.
Turn the crown forwards or backwards. Synchronise the
seconds by pushing the crown back to position 1 to
coincide with a given time signal.
SECOND TIME ZONE (calibre 1128, fig. VI)
Thanks to the “24-hour” hand with its triangular point,
travellers can read the time back home at a glance on
the 24-hour scale on the rotating bezel. In order to do
so, the triangle on the bezel must point to 12 o’clock on
the dial.
The bi-directional turning bezel (calibre 1128)
allows a third time zone to be read. To do so, the bezel
must be turned so that the “24 hour” hand points to this
third time zone on the bezel. When read off against the
scale on the bezel, the “24 hour” hand will then indicate
the time in this third time zone.
In order to read the time back home, the triangle of the
bezel must be returned to point to 12 o’clock on the
dial.
SECOND TIME ZONE (calibre 2628, fig. VII, calibre
3603, fig. XX)
Thanks to the “24-hour” hand with its triangular point,
travellers can read the time back home at a glance on the
24-hour scale at the centre of the dial.

Omega mechanical watches with a certified chronometer movement
Omega watches bearing the chronometer inscription (in
accordance with the certificate issued by your authorised Omega retailer) are high-precision timepieces that
have passed the precision tests of the Official Swiss
Chronometer Testing Institute (Contrôle Officiel Suisse
des Chronomètres, COSC).
This neutral and independent body individually tests each
movement for 360 consecutive hours, during which it is
placed in the five common wrist positions and exposed to
three different temperatures.
To earn the title of chronometer, the mechanical movement’s average daily variation in rate must be between
–4/+6 seconds per day, or a precision of 99.99%, the
highest precision attainable by a mechanical movement.

The precision of a mechanical movement depends on the
individual habits of the wearer and can therefore vary. A
qualified Omega watchmaker can adjust the precision of
a watch to within the Omega tolerances, which are from
-1 to +6 seconds per day.
Other Omega mechanical watches
The majority of watches that do not have a chronometer
certificate have average precision tolerances of between
-1 and +11 seconds per day.
The precision of a mechanical movement depends on the
individual habits of the wearer and can therefore vary. A
qualified Omega watchmaker can adjust the precision of
a watch to within the Omega tolerances.
Quartz watches
All Omega quartz movements are produced in accordance
with Omega’s highly renowned procedures and quality
standards. Ambient temperature may affect the precision
of quartz movements, which can lead to variations of
between -0.5 and +0.7 seconds per day.
Quartz watches with thermocompensation
(calibre 1680)
This movement is fitted with an electronic module that compensates for the effects of temperature on the movement’s
precision. These watches are accurate to within +/- 0.055
seconds per day.
The precision of a mechanical watch cannot be compared
to that of a quartz watch, given that the two are based on
different technologies.

Your OMEGA Seamaster Professional Diver is the watch for
professional and amateur divers, as well as demanding
sportsmen and –women. A robust design, the new helium
escape valve (exclusive OMEGA patent), together with
all the protection systems, offer optimal security and
reliability. In order to ensure that your watch remains
watertight, we recommend that you have it checked by
an authorised OMEGA partner every year.
Helium escape valve (fig. 1)
Why a helium escape valve? Air cannot be used for deepsea dives, since
nitrogen (a constituent element of air)
becomes toxic at a depth of 60 metres.
Therefore, when carrying out work
at great depths, professional divers
stay in a diving bell for several days,
breathing a mixture of gases containing a high proportion of helium. The
pressure is gradually increased to
reach the pressure at the working depth. The divers, still
inside the bell, are then lowered to the working site. They
leave the bell to carry out their work.
Once their work is complete, they re-enter the bell,
which is then raised to the surface. Pressure is then
returned to atmospheric levels and this is when the valve
must be opened (only for deepsea dives lasting several
days).
The helium molecules diffuse and penetrate the material of
the gaskets. The quantity is sufficient to push out the crystal
during the return to atmospheric pressure
. To avoid this,
the Seamaster Professional Diver is equipped with a valve
specially developed by OMEGA.

How to use the helium escape valve (fig. 2)
In its normal position (fig. 2.1), the OMEGA helium escape
valve is perfectly watertight thanks to gasket (B), but it is
not functional, since it is screwed in
.
During the decompression phase, unscrew the crown of the
valve in order to release the mechanism (fig. 2.2). The valve
is now watertight from the outside. As the interior pressure
becomes greater than the exterior pressure, it pushes the
gasket A out of its seating, thus releasing the gas (fig. 2.3).
Once the pressure is equalised, gasket A returns to its original position, pushed by the spring C (fig. 2.2).
This operation is automatically repeated several times
during the decompression phase. Once atmospheric pressure is reached, screw in the crown of the valve (fig.
2.1).
Note:
Even if the valve is unscrewed, the watch is still water resistant to 50 metres. However, complete water resistance is
guaranteed by gasket (B) when the valve is screwed in.

To read the time, the position of the central seconds hand
is used. For observations over longer periods, the indications of the totalisers (hours and minutes) are also used.
Using the tachymetric scale
Example: calculating the speed of a car.
Record the time the car takes to cover a distance of 1
kilometre. Read off the speed on the tachymetric scale
indicated by the central seconds hand. In this case, the
car is travelling at 120 km/hr.
