Introduction

We congratulate you on the purchase of your Jaeger-LeCoultre

watch and thank you for your conﬁ dence.

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 inﬂ uence of gravity, mag-

netic ﬁ elds, 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.

Water resistance

Jaeger-LeCoultre Reverso watches are water-resistant to

3 Atm. This property is identiﬁ able 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 signiﬁ cant

risks of hard knocks, such as windsurﬁ ng 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 deﬁ nitely 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, afﬁ xed or

engraved on the back of your watch, certiﬁ es 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 ﬁ elds,

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 ofﬁ cial 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 ofﬁ cial Service Centres listed at the end of the guarantee

booklet.

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 (ﬁ g. 1) and lift up the link (ﬁ g. 2).

Avoid the 2 links on either side of the clasp.

Proceed in the same way for the following link (ﬁ g. 3) if you

want to remove a single row of links (or the 2nd, 3rd, etc. if you

want to remove 2, 3... rows of links).

Take out the two bars (ﬁ g. 4).

Remove the row(s) of links (ﬁ g. 5).

Place the 2 ends of the bracelet back together and insert a

bar (ﬁ g. 6).

Tip over the link, press on the end of the bar pivot and push

your link down until it clicks (ﬁ g. 7).
