Introduction
We congratulate you on the acquisition of your Jaeger-LeCoultre watch, and
thank you for your condence in us.
We invite you to consult the operating instructions and hope your Jaeger-
LeCoultre timepiece brings you great enjoyment.
Accuracy and precautions for use
Manually-wound or automatic mechanical watches
The accuracy of watch models with mechanical movements is determined by the
balance.This oscillates at a rate of 21,600 or 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 inuence of gravity, magnetic elds, 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 temperament and your activities could be the cause of slight ir-
regularities. If you observe a discrepancy in the running of your watch, we advise
you to entrust it to an authorised Jaeger-LeCoultre retailer who will perform the
necessary adjustments.Watches with mechanical movements must not be used
for sports involving signicant risk of impact or abrupt actions, such as golf or
tennis for example.
Quartz models
Quartz models are accurate to within 2 to 3 minutes a year. Jaeger-LeCoultre quartz
watches contain a battery and electronic elements. When performing
maintenance, your ofcial Jaeger-LeCoultre Service Centre or your author-
ised Jaeger-LeCoultre retailer will recover such components and ensure
they are disposed of in accordance with the standards in force.
Water resistance
Your Jaeger-LeCoultre watch is water-resistant to 10 bar/atm.The water resist-
ance of your watch is identiable by the symbol engraved on the back.
This means that your timepiece has been tested at an overpressure of 10 bar,
corresponding to an immersion pressure of 100 metres (1 bar/atm = approx.
10 metres).

30
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 the water resistance
may be affected by certain activities, it is recommended that the user:
- have the water resistance of the watch checked by an authorised Jaeger-
LeCoultre retailer, in accordance with the recommendations of the Jaeger-
LeCoultre Manufacture and at any event after each opening of the case, in
which case it is advisable to perform an air overpressure test
- check when making the purchase that the strap or 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 shocks (having the
watch checked after any violent impact)
- avoid the use of the controls, push-piece or time-setting crown while under
water or before the watch has dried after immersion
- be sure to restore the time-setting crown and the push-pieces to their nor-
mal position (or, where applicable, close the compression keys) after every
manipulation
- rinse the watch with fresh water after use in sea-water.
Furthermore, it is vital to have the water resistance of your watch checked by
an authorised Jaeger-LeCoultre retailer at least once every two years, and at any
event before any period during which it is liable to undergo prolonged and/or
regular immersions.
“1000 Hours Control” test
Jaeger-LeCoultre submits all its watches to the stringent “1000 Hours Control”,
a unique battery of comprehensive and rigorous internal tests lasting a full 1000
hours.
The“1000 Hours Control”seal or legend placed or engraved on the back of your
watch certies that the latter has undergone this programme of observation in
our laboratories and has successfully passed all the tests relating to regularity
of rate, temperature, atmospheric pressure, resistance to shocks and magnetic
elds, as well as water-resistance trials.Your watch is thus capable of withstanding
the daily stresses and strains that await it when worn on your wrist.

31
English
The criteria of the “1000 Hours Control” programme considerably exceed the
standards of ofcial timing tests, which deal only with part of the movement.
Jaeger-LeCoultre tests not only the movement prior to its being cased up in the
watch, but also the watch as a whole.
Compression keys
The patented compression key system, which is tted to the crowns of the
Master Compressor line models, can apply strong compression to one of the
four crown seals, thereby ensuring impeccable long-term water-resistance.
The position of the compression key, “open”or “closed”, is indicated by the ar-
row symbols (viewed from the front):
- If the indication is a white arrow, the compression key is in the compressed
seal position (“closed”); the key must be closed when you wear your watch
and when you are taking part in sporting activities.You must not make any
adjustments or set the time in this position, since this might damage the
gaskets.
- If the indication is represented by two red arrows, the compression key is in
the non-compressed seal position (“open”); in this conguration, you may
proceed to start the watch and adjust the functions according to the indica-
tions below.
The transition from the “closed” to the “open” position, or vice-versa, is per-
formed by turning the key using the wings in the direction indicated by the
arrow(s).
Note
The water-resistance function of the compression key is separate from the op-
eration of the crown itself. Even in the closed position, the key does not lock the

crown. So in practice it is possible to operate the crown when the key is in the
compressed gasket position. However, as mentioned earlier, it is extremely inad-
visable to make adjustments in this position, since this might damage the gaskets.
We recommend that you rst turn the compression key to the “open” position
before making any adjustments to your watch.
Adjusting the bracelet
You can adjust your steel bracelet yourself. However, if you have a gold model,
we advise you to entrust it to the nearest approved Jaeger-LeCoultre retailer, or
to contact one of our ofcial Service Centres listed at the end of the guarantee
or warranty document.
Adjusting the steel bracelet
Place the watch on your wrist. You can thus see how many links need to be
added or removed.
Remove your watch by simultaneously pressing the push-pieces on either side
of the clasp.
Hold the bracelet near the clasp. Using the adjustment tool, press the end of
the bar (g. 1) and lift up the link (g. 2). Avoid the two links on either side of
the clasp.
Proceed in the same way for the following link (g. 3) if you want to remove a
single row of links (or the second, third, etc. if you want to remove two, three,
or more rows of links).
Take out the two bars (g. 4).

English
Remove the row(s) of links (g. 5).
Place the two ends of the bracelet back together and insert a bar (g. 6).
Tip over the link, press on the end of the bar pivot and push your link down
until it clicks (g. 7).

Adjusting the clasp
The clasp on metal bracelets and articulated rubber straps is tted with an ad-
justment system enabling you to lengthen or shorten your wristlet by 4 mm on
either side, for greater wearer comfort.
Using the ne adjustment system
Transition from the long position to the short position:
Remove your watch.
Hold your clasp open between the thumb and forenger of one hand, with the
wristlet section in your other hand (g. 1).

English
Lift up the clasp cover so as to release the
tip-over part of the bracelet section from
its groove (g. 2).
Fig. 2 Long position
Push the tip-over part of your bracelet
section and place it in its groove, facing
the opposite way to its initial position
(g. 3).
Fig. 3 Shortened position
The switch from the short to the long
position is made in the same way, but in
the opposite direction (g. 4).
