Introduction
We would like to thank you for the confidence
you have placed in Jaeger-LeCoultre. Our
Maison has applied all its expertise and exacting
standards to the creation of this model.
We invite you to consult the operating
instructions and hope your Jaeger-LeCoultre
timepiece brings you great joy.
Accuracy and precautions for use
MANUALLY-WOUND OR AUTOMATIC
MECHANICAL WATCHES
The accuracy of watch models with mechanical
movements is determined by the balance
wheel. This oscillates at a rate of 28,800
vibrations per hour. Despite all the care that the
master watchmakers of the Jaeger-LeCoultre
Manufacture have lavished on building and
assembling your watch, its accuracy is subject
to the influence of gravity, magnetic fields,
accidental impacts, and the ageing of the oils.
The accuracy of a watch is measured by its
regularity of rate in various positions.

Your individual activities could be the cause
of slight irregularities in the working of your
timepiece. If you observe a discrepancy in the
way your watch runs, we advise you to entrust it
to an authorised Jaeger-LeCoultre retailer who
will make the necessary adjustments. Watches
with mechanical movements must not be used
for sports involving significant risk of impact or
abrupt actions, such as golf or tennis.
Water resistance
Your Jaeger-LeCoultre watch is water resistant
up to 10 bar. Its water resistance can be identi-
fied by the symbol and/or by “10 bar”
engraved on the case-back. This means that
your model has been tested at an overpressure
of 10 bar, corresponding to an immersion
pressure of 100 metres (1 bar = ±10 metres).
In accordance with the ISO 22810/NIHS 92-10
standard, in order to guarantee the durability
of the watch’s characteristics over time, and
as water resistance may be affected by certain
activities, it is recommended that you:

27
ENGLISH
- have the watch’s water resistance checked
by an authorised Jaeger-LeCoultre retailer
at least once every two years. It is essential
to have such a check carried out each time
your watch is opened, and before any period
in which it is liable to undergo prolonged and/
or regular immersions.
- check when making the purchase that the
bracelet is suitable for the intended use.
- avoid subjecting the watch to excessively
abrupt temperature changes.
- protect the watch from being dropped or
suffering other accidental impacts, and have
the water resistance checked after any severe
impact.
- avoid using the controls, push-piece, or time-
setting crown while under water, or outside
the water, if the watch is not yet dry after
immersion.
- restore the time-setting crown and the push-
pieces to their normal positions, or where
applicable, close the compression keys after
every manipulation.

28
- rinse the watch with fresh water after use in
sea water.
You may use your watch while swimming,
as long as you do not exceed the immersion
pressure and do not engage in any water sports
that could cause impacts. This watch is not a
piece of diving equipment and should not be
used as such. Also, note that leather straps are
not suited for aquatic activities.
“1,000 Hours Control” test
Jaeger-LeCoultre submits all its watches to
the stringent “1,000 Hours Control”, a series
of comprehensive and rigorous internal tests
lasting a full 1,000 hours.
The “1,000 Hours Control” seal, placed or
engraved on the back of your watch, certifies
that the timepiece has successfully passed all the
tests relating to regularity of rate, temperature,
atmospheric pressure, and resistance to
shocks and magnetic fields, as well as water-
resistance trials. Thus, your watch is capable of
withstanding the daily stresses and strains. The

29
ENGLISH
criteria of the “1,000 Hours Control” programme
considerably exceed the standards of official
timing tests, which deal only with part of the
movement.
Jaeger-LeCoultre tests not only the movement
prior to being cased up in the watch, but also
the watch once it has been assembled.

Functions
Thanks to a mechanically powered disc indi-
cating the 24 time zones of the international
GMT system, your Jaeger-LeCoultre Polaris
Geographic WT watch features a display of
multiple parts that indicate:
- The time (in hours, minutes and seconds) and
date where you live, i.e. local time.
- Universal time, i.e. the simultaneous reading of
the time in each of the world’s 24 time zones.
- The hour and minute of the city you choose as
the “favoured time zone”, in the small dial at
6 o’clock.
- The power reserve, which enables you to
control the winding level of your watch at all
times.
Use
Crown A at 3 o’clock enables the user to:
- Wind the watch if it has not been worn for
more than 38 hours.

31
ENGLISH
- Set the local time and the reference time
depending on the position the crown is in
(with the time in the 24 time zones and in
the small dial of the favoured time zone
automatically changing as a result).
- Synchronise the local time with the time of all
the time zones.
Crown B at 10 o’clock enables the user to:
- Turn the city disc and the 24-hour disc.
- Choose the desired city as the favoured time
zone, by positioning it opposite the triangular
marker located at 6 o’clock. This operation
automatically sets the corresponding time in
the favoured time zone indicated on the small
dial at 6 o’clock.
Corrector C at 2 o’clock enables the user to:
- Set the date.
- Adjust the date for months with fewer than
31 days.
