Introduction
We congratulate you on the purchase of your Jaeger-LeCoultre
watch and thank you for your confidence.
The sublime beauty of the secret rock-setting technique,
perfected by Jaeger-LeCoultre, allows the brilliance of the
precious stones to shine through without revealing even a
glimpse of the underlying material. Set with this technique,
the baguette-cut gemstones completely cover the Grande
Reverso case.
We invite you to consult the operating instructions and
we wish you great pleasure with your Jaeger-LeCoultre
timepiece.

Accuracy
Mechanical models with manual or automatic
winding
The precision of the mechanical models is determined by the
balance.The latter performs 21,600 or 28,800 vibrations per
hour depending on the model (see technical characteristics).
Despite all the care that the Jaeger-LeCoultre master-
watchmakers have lavished on making and assembling your
watch, its accuracy is subject to the influence of gravity, mag-
netic fields, shocks, as well as ageing of the oils. Its accuracy is
measured by its rate regularity in various positions.
The nature of you temperament and of your daily activities
may cause slight variations in timekeeping. If you were to
notice that your watch is running slow or fast, we advise you
to take it to an approved Jaeger-LeCoultre retailer, who will
make any necessary adjustments.
Quartz models
The quartz models are accurate to within 2 to 3 minutes
per year.

27
Water resistance
Jaeger-LeCoultre Reverso watches are water-resistant to
3 Atm. This property is identifiable by the symbol
engraved on the case-back. This means that your timepiece
has been tested at an immersion pressure corresponding to
30 metres.
You can use your watch while swimming or diving from the
edge, but not from a diving board. It should not be used either
for undersea diving or for sports where there are significant
risks of hard knocks, such as windsurfing and waterskiing.
Please also note that leather straps are not suitable for aquatic
activities.
It is essential to have the water resistance of your watch
regularly checked by an approved Jaeger-LeCoultre retailer,
and definitely before a period of intensive use.

The "1000 Hours Control" test
by Jaeger-LeCoultre
Jaeger-LeCoultre subjects its watches to the rigorous "1000
Hours Control" test programme. Unique in its kind, this test
consists of 1000 hours of comprehensive, stringent checks.
The "1000 Hours Control" seal or marking, affixed or
engraved on the back of your watch, certifies that it has
undergone this observation programme in our laboratories
and has successfully passed all tests. The latter include rate
regularity checks, reactions to changes in temperature and
barometric pressure, resistance to shocks and magnetic fields,
as well as water-resistance tests at pressures of 3 atmospheres.
Your watch is therefore capable of withstanding the trials of
everyday life when you wear it on your wrist.
The criteria of the "1000 Hours Control" programme go far
beyond the official timekeeping test standards, which concern
only part of the movement. Jaeger-LeCoultre tests both the
movement and the fully cased-up 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 near-
est approved Jaeger-LeCoultre retailer, or to contact one of
our official Service Centres listed at the end of the guarantee
booklet.
Adjusting the steel bracelet

links need to be added or removed.

pieces on either side of the clasp.
Hold the bracelet near the clasp. Using the adjustment tool,
press the end of the bar (fig. 1) and lift up the link (fig. 2).
Avoid the 2 links on either side of the clasp.

Take out the two bars (fig. 4).
Remove the row(s) of links (fig. 5).
Place the 2 ends of the bracelet back together and insert a

of your bracelet section
and place it in its groove,
facing the opposite way
to its initial position
(fig. 3).
Fig. 3 Shortened position
The transition from
the short to the long
position is done in the
same manner, but in the
opposite direction (fig. 4).
