Introduction
We would like to thank you for the confidence
you have placed in Jaeger-LeCoultre. Our Mai-
son has applied all its expertise and exacting
standards to the creation of this model.
We invite you to consult the operating instruc-
tions and hope your Jaeger-LeCoultre time-
piece brings you great joy.
Accuracy and precautions for use
MANUALLY-WOUND OR AUTOMATIC
MECHANICAL WATCHES
The accuracy of watch models with mechan-
ical movements is determined by the balance
wheel. This oscillates at a rate of 28,800 vi-
brations per hour. Despite all the care that the
master watchmakers of the Jaeger-LeCoultre
Manufacture have lavished on building and as-
sembling your watch, its accuracy is subject to
the influence of gravity, magnetic fields, acci-
dental impacts, and the ageing of the oils. The
accuracy of a watch is measured by its regular-
ity of rate in various positions.
ENGLISH

22
Your individual activities could be the cause of
slight irregularities in the working of your time-
piece. 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 5 bar. Its water resistance can be identi-
fied by the symbol and/or the engraving:
“5 bar” on the case-back. This means that your
model has been tested at an overpressure of 5
bar, corresponding to an immersion pressure of
50 metres (1 bar = ±10 metres).
In accordance with the ISO 22810/NIHS 92-20
standard, in order to guarantee the durability
of the watch’s characteristics over time, and as
water resistance may be aected by certain ac-
tivities, it is recommended that you:

23
- 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 suf-
fering other accidental impacts, and have the
water resistance checked after any severe im-
pact.
- avoid using the controls, push-piece, or
time-setting crown while under water, or out-
side 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.
ENGLISH

24
- 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 pres-
sure 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.
“1000 Hours Control” test
The Jaeger-LeCoultre Manufacture pays close
attention to the quality and to the final checks
of its watches.
The 1000 Hours Control is a series of internal
qualification tests for each of the models in our
collection, as well as internal tests on the pro-
duction of your watch, which go beyond ocial
timing tests. These tests include checks of the
movement before and after being cased up in
the watch and cover the whole watch once it
has been assembled, in the conditions closest
to daily wear.

25
The “1000 Hours Control” legend, or the “ ”
seal engraved on the back of the watch certi-
fies that each of the models from our collection
has successfully undergone all of the qualifica-
tion tests, and that your watch has successful-
ly undergone all of the production tests. These
ensure regularity of rate, resistance to varia-
tions in temperature and atmospheric pressure,
ability to withstand shocks and magnetic fields,
as well as water resistance.

STARTING THE WATCH
Crown in position 0.

27
A few clockwise turns of the crown are enough
to start your watch.
It will then automatically wind up when you
wear it. Please note that the crown does not
lock when winding, even when the watch is
fully wound.
SETTING THE TIME
Pull the crown out to position 1.
The movement is then locked ("stop seconds"
function). To enable precise time-setting to
the nearest second, stop the seconds hand at
60. Move the hands forward clockwise to the
desired time and, on the hour signal, push the
crown back to position 0. The watch starts
running again.
SETTING THE DAY, DATE, MONTH, AND
MOON PHASE
The day, date, month, and moon-phase
adjustments can be carried out by pressing
the correctors A, B, C and D using the stylus
provided with your watch.
ENGLISH

28
SETTING THE DAY
Press corrector D at 10 o’clock.
Each press moves the disc one day forward.
SETTING THE DATE
Press corrector B at 4 o’clock.
Each press moves the date hand one day
forward.
For months with fewer than 31 days, repeat this
process to reach the 1st of the following month.
SETTING THE MONTH
Press corrector A at 2 o’clock.
Each press moves the disc one month forward.
SETTING THE MOON PHASE
Press corrector C at 8 o’clock.
Each press moves the disc one day forward.
To ensure correct adjustment, calculate the
number of days that have elapsed since the last
full moon using the calendar at the end of this
user manual. Centre the moon in the aperture,
then move the disc forwards according to the
number of days that have elapsed since the last
full moon.
