Introduction
We would like to thank you for the confidence 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 instructions 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 mechanical movements is determined by the
balance wheel. This 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 influence of gravity, magnetic fields, acci- dental impacts,
and the ageing of the oils. The accuracy of a watch is measured by its
regular- ity 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 discrepancy in the way your watch
runs, 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 significant risk of impact or abrupt
actions, such as golf or tennis. Water resistance Your Jaeger-LeCoultre watch
is water resistant up to 3 bar. Its water resistance can be identified by the
symbol and/or the engraving: “3 bar” on the case-back. This means that your
model has been tested at an overpressure of 3 bar, corresponding to an
immersion pressure of 30 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 affected by
certain activities, it is recommended that you:
- have the watch’s water resistance checked by an authorised Jaeger-LeCoultre retailer at least once every two years. It is essential to have such a check carried out each time your watch is opened, and before any period in which it is liable to undergo prolonged 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 suffering other accidental impacts, and have the water resistance checked after any severe impact.
- 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 immersion pressure and do not engage in any water sports that could cause impacts. This watch is not a piece of diving equipment 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
internal qualification tests for each of the models in our collection, as well
as internal tests on the pro- duction of your watch, which go beyond official
timing tests. These tests include checks of the movement before and after
being cased up in the watch and cover the whole watch once it has been
assembled, in the conditions 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
undergone 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 in temperature and atmospheric pressure, ability to
withstand shocks and magnetic fields, as well as water resistance.
Technical specifications
- Manually wound mechanical movement, Jaeger-LeCoultre Calibre 853A. – 21,600 vibrations/hour.
- Power reserve: approximately 42 hours.
Use
STARTING THE WATCH
Your Reverso Tribute Moon watch is equipped with a 42-hour power reserve,
during which time it can operate without any additional winding.
WINDING
Crown in position 0.
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 isadvisable to wind your watch
regularly.
FRONT
SETTING THE HOURS AND MINUTES
Pull the crown out to position 1.
Move the hands clockwise until the desired time is displayed.
When the operation is complete, push the crown back to position 0.
SETTING THE DATE AND MOON PHASE
The date and moon phase adjustments can be carried out by pressing the
correctors A and B using the stylus provided with your watch.
The lunar calendar included at the end of this user manual can serve as
reference for these adjustments.
SETTING THE DATE
Press corrector A at 4 o’clock. Each press moves the date hand one day
forward. For months with fewer than 31 days, repeat this process to reach the
1st of the following month.
SETTING THE MOON PHASE
Press corrector B 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.
This is because the automatic date-change mechanism is already in action
between these times.
BACK
ADJUSTING THE SECOND TIME ZONE
In the GMT (Greenwich Mean Time) system that is used practically throughout
the world, the earth is divided into 24 time zones, each corresponding to 15
degrees’ longitude (see table below).
In each of these time zones, the official time is the same and it changes by
one hour when moving from one zone to the next.
Setting out from the Greenwich meridian, the central or 0 point of time zones,
12 zones have been defined from +1 to +12 hours moving eastward, and 12 others
from 0 to -11 hours moving westward.
To set the second time zone indication of the Reverso Tribute Moon watch, turn over the case of your watch (to the back face), without closing it back up. On the top end of the case, you will note the presence of a “catch”.
By sliding it sideways, you will cause the time display on the back dial to jump by one hour each time, thus, enabling you to correctly set the second time zone display. During this operation, it is also recommended that you take into account the day/night indication on the 6-hour disc. As a reminder, the minutes are displayed identically on both of the dials. It is not possible to indicate a time difference of a fraction of an hour, as is the case in some regions of the world (India, Iran, Nepal).
