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 precision of mechanical watches is determined by the balance.This oscillates
at a rate of 28,800 vibrations per hour.
Despite all the care that the master watchmakers of the Jaeger-LeCoultre Manu-
facture have lavished on building and assembling your watch, its accuracy is sub-
ject to the inuence of gravity, magnetic elds, impacts and ageing of the oils.The
precision 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 make 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.
Water resistance
Your Jaeger-LeCoultre watch is water-resistant to 5 bar/atm.The water resistance
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 5 bar, corresponding to an
immersion pressure of 50 metres (1 bar/atm = approx. 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 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 dealer, 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 recommended that the test be carried out with increased
air pressure

22
- 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 (have 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
- restore the time-setting crown and the push-pieces to their normal positions
(or, where applicable, close the compression key) after every manipulation
- rinse the watch with fresh water after use in sea water.
You may use your watch during short swims, and when jumping in from the
edge of a swimming pool but not from a diving board. Your watch must not
be used for scuba diving or for sports involving signicant risk of impact, such
as windsurng or water-skiing. Also note that leather straps are not suited to
aquatic activities.
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 and 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.
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 being cased up in the
watch, but also the watch as a whole.

Technical specications
- Manually-wound mechanical movement, Jaeger-LeCoultre Calibre 383
Dual-Wing.
- 28,800 vibrations/hour.
- Power-reserve: approximately 50 hours.
- Power-reserve of second time zone: approximately 50 hours.
- Water-resistance: Water-resistant to 5 atm.
Movement
Jaeger-LeCoultre Calibre 383.
Important note regarding the power-reserves of the Calibre 383 Dual-Wing.
The Dual-Wing movement of the Duomètre Unique Travel Time watch model
comprises two barrels. The rst barrel provides a 50-hour power-reserve for
the watch’s time function.The second barrel, independently of the rst, provides
a 50-hour power-reserve for the second time zone. The functions thus do not
cause any loss of energy or isochronism in the escapement.The power-reserve
for the time function can be read on the hand between 4 and 5 o’clock. The
power-reserve for the second time zone can be read on the hand between
7 and 8 o’clock.
In both cases, the power-reserve is at its maximum when the hand is positioned
opposite the “+” symbol. As energy is consumed, the hand will gradually point
towards the “-” symbol. When the hand is opposite the “-” symbol (after ap-
proximately 50 hours), this indicates that the power reserve has been exhaust-
ed.This is the last chance to wind up the watch without losing the settings.

24
Both barrels can be wound using crown A, in position 1.
By turning the crown clockwise, you wind up the second time zone (and there-
fore restore its power-reserve). By turning the crown anti-clockwise, you wind up
the time function barrel (and therefore restore its power-reserve).
Important:
Although the two power-reserves are independent, it is vital that both are wound
before the timepiece can be used. If one of the power-reserves is depleted,
the movement will stop (no damage will be caused to the movement). It will
thus be necessary to wind the two power-reserves according to the instructions
to restart the calibre.
Functions
The Duomètre Unique Travel Time is the rst world time watch in which the
second time zone can be set to the minute.
Thanks to the Dual Wing concept, which enables the addition of functions with-
out disrupting the power supplied to the regulating organ, the second time zone
of your Duomètre Unique Travel Time does not lead to energy loss.
Consequently, the Duomètre Unique Travel Time displays the following:
- The hours, minutes and second of the time where you live (local time)
- The hour, minute and day/night GMT indicator of the city selected for the
second time zone.
- The power-reserves which enable the winding levels to be controlled.

Use
Starting the watch
Crown in position 1
The watch can be started by turning the crown clockwise to wind on the barrel
of the second time zone and anti-clockwise to wind that of the reference time.
The watch is fully wound when the two power-reserve hands reach the “+”
symbol. There is no stop to tell you that the movement has been fully wound,
as excess winding is absorbed by a slipping spring. This prevents damaging the
going train.
Setting the time
Adjusting the globe position and indication of the 24-hour time zones
- The globe and the time zones are connected, enabling the globe and time
zone indication to be moved with the aid of the two push-pieces.
- These are based on the time zone of reference (the main time zones are
visible on the back of the piece). They can be aligned to the hour marker
which is found at 6 o'clock.

Setting the reference time
Crown in position 3
- The movement is then locked (“stop seconds” function).To enable time setting
accurate to one second, stop the time function seconds hand (gold or rhodium
plated-hand) at 60.
- 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.
Setting the second time zone as the reference time
Crown in position 2
- Rotating the crown moves the minute hand of the second time zone
forward by intervals of 1 minute at a time. To move through the hours more
rapidly, it is possible to move the minute hand back and forth above the hours
disk, which causes the disk to move forward by one hour.
- Align the time of the second time zone with the reference time.
- Make sure to respect the day/night indication on the globe.
The destination time is now ready for setting.
