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).
Fig. 1 Fig. 2

33
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).

37
English
Crown A is then in position 1. A few clockwise turns of the crown are enough
to set the watch running. 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.
When the operation is completed, turn the compression key to the “closed”
position in the direction of the arrows.
Setting the time
Crown A
Turn the compression key to the “open” position in the direction of the arrow.
Then pull crown A out to position 3.
The movement is then locked (“stop seconds” function).
In order to set the time to the nearest second, pull the crown to stop the
second-ow disk when the second display appears either entirely white or en-
tirely red.
Move the hands forward clockwise to the desired time and, on the hour signal,
push the crown back to position 1.The watch starts running again.
When the operation is completed, turn the compression key to the “closed”
position in the direction of the arrows.

Setting the date
Crown A
Turn the compression key to the “open” position in the direction of the arrow.
Then pull crown A out to position 2.
Move the date forward by turning the crown anti-clockwise. Perform the re-
quired number of turns until the desired date is displayed.
Note: date correction should not be performed between 10.30 p.m. and 3.30
a.m. During this period the automatic date-change mechanism is already in
action.
When the operation is completed, push the crown back to position 1 and turn
the compression key to the “closed” position in the direction of the arrows.
Operating the chronograph
The central seconds hand on the Master Compressor Extreme World
Chronograph displays the chronograph seconds to the nearest eighth of a sec-
ond. A counter located at 3 o’clock tallies the minutes up to 30 minutes (after
one revolution it will start counting another 30 minutes). Another counter at 9
o’clock tallies the hours up to 12 hours (after one revolution it will start counting
another 12 hours).
- Push-piece at 2 o’clock: this push-piece starts and stops the chronograph
function.
- Push-piece at 4 o’clock: this push-piece resets the counters and the central
seconds hand.When timing is in progress, pressing this push-piece has no ef-
fect.
Each of these two push-pieces features a wing-nut with a patented com-
pression system.This enables additional compression of one of the three push-
piece gaskets, to ensure optimum water resistance.
Another advantage of this system is that it enables the push-pieces to be locked
in the “closed” position, thereby preventing any unintentional operation of the
chronograph.
To use the chronograph functions, move the push-pieces into the “open” posi-
tion by turning the wing-nuts a quarter-turn downward for the push-piece at 2
o’clock (for starting and stopping) and upward for the push-piece at 4 o’clock

39
English
(for resetting).The non-compressed gasket position (“open”) will be indicated by
an arrow (front view of watch).
Timing
- The chronograph is activated by pressing the push-piece at 2 o’clock once.
The central seconds hand will turn, and the minute and hour counters will
run. Pressing the push-piece at 2 o’clock again will stop the chronograph,
enabling the time measurement to be read.
- Reset by pressing the push-piece at 4 o’clock to be ready to perform another
time measurement.
- It is possible to add up several timing operations by pressing again on the
push-piece at 2 o’clock (without having to reset the counters).
Timing is re-started and is added to the previous measurement.
Once the timing operation is complete, move the push-pieces to the com-
pressed gasket (“closed”) position by turning the wing-nuts in the direction
shown by the arrows, i.e. a quarter-turn upward for the push-piece at 2 o’clock
(for starting and stopping), and a quarter-turn downward for the push-piece at
4 o’clock (for resetting).
World time function
Your watch features an ingenious system of world time display that can tell the
time simultaneously in 24 cities around the world.
The simultaneous reading of the time in the world’s 24 time zones is thus pos-
sible thanks to the city disc and the 24-hour turning ring.This reading necessitates
a pre-setting involving setting the local time zone by positioning the correspond-
ing city at 6 o’clock (the reference time for the mechanism).
Compressed seal position
(“closed”)
Position of seal without compression
(“open”)

40
How to proceed
- Set the hour and minute according to the instructions above (local time).
- Crown C (one single position, not pulled out) moves the city disc: turn the
crown either way in order to display the city which corresponds to your local
time next to the numeral ‘6’ on the dial (i.e. at 6 o’clock).
- The 24-hour ring will now display the same time as your local time opposite
the number ‘6’ and therefore opposite the reference city which you placed in
this position.
Once this pre-setting is completed:
- The city disc will not move.
- The 24-hour ring will turn in unison with local time (the time in your refer-
ence city), but will go round the dial once in 24 hours.The time in each city
will be updated in accordance with the local time.
- You can thus read whenever you wish the time in any of the cities indicated
on the city disc by reading the hour opposite the relevant city on the 24-hour
ring, and the central minute hand.
- If you move into another time-zone, the operation will need to be repeated
so as to display at 6 o’clock the new reference city corresponding to the new
time zone.

If time is set at 5 o’clock, you will
see that the 24-hour ring displays
‘5’ opposite the city at 6 o’clock
2 hours later, at 7 o’clock, you will
see that the 24-hour ring has moved
forward, indicating ‘7’ opposite the city
at 6 o’clock.You can read the time
in all time-zones simultaneously.

41
English
Note: Regions where the ofcial time differs by a fraction of an hour (India,
Nepal, Iran) are not included in the city disc.
Case shock-absorbing system
Your watch case is equipped with a mechanism that enables it to absorb ac-
cidental impacts and thus protect the movement.The case is made up of two
sections:
- The central section, made of titanium, is a water-resistant case protecting the
movement.
- The external section consists of the bottom support for the bezel.
The case containing the movement is housed inside the support and can move
in a vertical direction. In the event of an impact, an air-cushion mechanism ab-
sorbs 50% of the force of the shock.

42
Interchangeable strap system
The base of your watch case is tted with an integrated interchangeability system
allowing the strap to be changed easily. It consists of a push-button which shifts
part of the space between the horns to release the strap’s spring bar from its
housing in the lugs.
Removing the strap sections from the case
- Hold the back of the watch case between the thumb and forenger of one
hand (A).
- Hold the strap section between the thumb and forenger of your other hand (B).
- With the thumb of hand B, push the button rmly against the case, and while
maintaining the pressure pull the strap section toward you to remove it.
- Proceed in the same way for the other section.
Closed position Position when the
strap is released

43
Fitting the strap sections onto the case
- Hold the back of the watch case between the thumb and forenger of one
hand.
- Hold the strap section between the thumb and forenger of your other hand,
and position its spring bar in the lug housings.
- Keeping the strap parallel to the case, insert the spring bar rmly into the
housings.
If you change straps, you can t the folding clasp on your new strap:
Removing the folding buckle
- With one hand hold the strap section, and take the tool in the other hand.
Position the tool vertically on the end of the visible spring bar. Press vertically,
and the spring bar will be released.
- While maintaining pressure on the spring bar, tilt the strap section outward to
release it.
Retting the folding buckle
- Place one end of the strap section spring bar in the appropriate clasp housing.
- With one hand hold the strap section in the housing, and take the tool in the
other hand. Position the tool vertically on the other end of the spring bar.
Press vertically.
- While maintaining pressure on the spring bar, bring the strap section back
against the clasp. Release the pressure on the bar at the last minute so that
the spring has time to insert the bar in its housing.
