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 mechan-
ical movements is determined by the bal-
ance wheel. Despite all the care that the mas-
ter 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 oils. The ac-
curacy of a watch is measured by its regularity
of rate in various positions.

25
ENGLISH
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 3 bar. Its water resistance can be identified
by the symbol and/or the engraving:
“3 bar” on the case-back. This means that your
model has been tested at an overpressure of
3 bar, corresponding to an immersion pressure
of 30 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 affected by certain
activities, it is recommended that you:

26
- 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.

27
ENGLISH
- 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.
“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
production of your watch, which go beyond
official 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.

28
The “1000 Hours Control” legend, or the “ ”
seal engraved on the back of the watch certifies
that each of the models from our collection has
successfully undergone all of the qualification
tests, and that your watch has successfully
undergone all of the production tests. These
ensure regularity of rate, resistance to variations
in temperature and atmospheric pressure,
ability to withstand shocks and magnetic fields,
as well as water resistance
