Introduction
We congratulate you on the acquisition of your Jaeger-LeCoultre watch, and
thank you for your condence.
We invite you to consult the operating instructions and hope your Jaeger-
LeCoultre timepiece brings you great enjoyment.
Accuracy
Manually wound or automatic mechanical watches
The precision of watch models with mechanical movements is determined by
the balance.The latter oscillates at a rate of 21,600 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, 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 irr-
egularities. 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.
Water-resistance
Your Jaeger-LeCoultre watch is water-resistant to 3 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 3 bar,
corresponding to an immersion pressure 30 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 Manu-
facture Jaeger-LeCoultre 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,
- check when making the purchase that the strap or bracelet is suitable for the
English

22
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 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 its being cased up in the
watch, but also the watch as a whole.

Use
Power reserve
Your Grande Reverso Calendar watch is equipped with a 45-hour power res-
erve, during which time it can operate without any additional winding.
Winding
Crown in position 1.
The watch is wound by turning the crown clockwise. The movement is fully
wound when the crown is locked.
Do not attempt to wind a manually-wound watch beyond the locking point.
To ensure good operating accuracy, it is advisable to wind your watch regularly.

Setting the time and the day
Pull the crown out to position 2.
Turn the hands clockwise through 12 midnight, the time when the day of the
week disc moves forward by one day. Having reached the desired day of the
week and set the exact time, push the crown back to position 1.
When setting your watch during the afternoon, you must rst turn the hands
through 12 noon.
When setting the time, in order to avoid disturbing the calendar functions, the
hands must never be turned anti-clockwise and never go beyond 3 a.m. Do not
perform any corrections between 10 p.m and 3 a.m.
Setting the date, month and moon phase
The date, month and moon-phase adjustments can be carried out by pressing
the correctors A, B and C using the stylus provided with your watch.

25
Setting the date
Press corrector B at 4 o’clock.
Each press moves the date hand one day forward.
For months with less than 31 days, repeat this process to reach the 1st of the
following month.
Setting the month
Press corrector A at 2 o’clock.
Each press moves the disc one month forward.
Setting the moon phase
Press corrector C at 8 o’clock.
Each press moves the disc one day forward.
To ensure correct adjustment, calculate the number of days that have elapsed
since the last full moon using the calendar at the end of this user manual. Centre
the moon in the aperture, then move the disc forwards according to the number
of days that have elapsed since the last full moon.
Note: date correction should not be performed between 10 p.m. and 3 a.m.
During this period the automatic date-change mechanism is already in action.
