INTRODUCTION
We would like to thank you for the confi-
dence 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 in-
structions 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 me-
chanical 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 lav-
ished on building and assembling your

24
watch, its accuracy is subject to the influ-
ence of gravity, magnetic fields, accidental
impacts, and the ageing of the oils. The ac-
curacy of a watch is measured by its regu-
larity 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 discrep-
ancy in the way your watch runs, we advise
you to entrust it to an authorised Jaeger-
LeCoultre retailer who will make the nec-
essary adjustments. Watches with me-
chanical 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 to 5 bar. Its water resistance can
be identified by the symbol and/or
the engraving: “5 bar” on the caseback.
This means that your model has been
tested at an overpressure of 5 bar, corre-

ENGLISH
25
sponding 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 activities, it is recom-
mended that you:
- have the watch’s water resistance checked
by an authorised Jaeger-LeCoultre retailer
at least once every two years. It is essen-
tial to have such a check carried out each
time your watch is opened, and before any
period in which it is liable to undergo pro-
longed 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
suering other accidental impacts, and
have the water resistance checked after
any severe impact.

26
- 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.
- 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 immer-
sion pressure and do not engage in any
water sports that could cause impacts.
This watch is not a piece of diving equip-
ment 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 in-
ternal qualification tests for each of the
models in our collection, as well as inter-
nal tests on the production of your watch,
which go beyond ocial timing tests.
These tests include checks of the move-
ment before and after being cased up
in the watch and cover the whole watch
once it has been assembled, in the condi-
tions closest to daily wear.
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 under-
gone 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

28
in temperature and atmospheric pressure,
ability to withstand shocks and magnetic
fields, as well as water resistance.
CARE INSTRUCTIONS
FOR LEATHER STRAPS
1. Keep the leather strap in a dry place
2. Avoid contact with water, cosmetics,
perfumes, alcohol and oily materials
3. To prevent leather from discolouring,
avoid wearing the watch:
- in a highly humid environment
- during a sporting activity: sweat dam-
ages the leather
- in prolonged exposure to sunlight
4. Wipe with a dry and soft fabric. Do not
dry in direct sunlight or near heat sources
