Introduction
We congratulate you on the purchase of your Jaeger-
LeCoultre watch and thank you for your confidence.
A genuine innovation, the Master Compressor Extreme
W-Alarm watch offers the two additional functions which,
until now, globetrotters could only dream of having in the
same watch : world-time display to find their way through
the various time zones, and an alarm mechanism featuring
unprecedented functionalities.
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. This accuracy is
measured by its rate regularity in various positions.
The nature of your temperament and of your daily activi-
ties 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.
Jaeger-LeCoultre quartz watches contain a battery
and electronic components. When performing
maintenance, your official Jaeger-LeCoultre Service
Centre or your authorised Jaeger-LeCoultre retailer
will take charge of their recovery and disposal in accordance
with the standards in force.
Water resistance
Jaeger-LeCoultre Master Compressor Automatic watches are
water-resistant to 5 bar/atm. This property is identifiable by
the
symbol engraved on the case-back. This means
that you can use your watch for short swims, and when diving
from the poolside, but not from a diving board. It must not
be used either for scuba diving or for sports where there are
significant risks of hard knocks, such as windsurfing and water-
skiing. Please also note that leather straps are not suitable for
aquatic activities.
It is also essential to have the water resistance of your watch
regularly checked by an authorised Jaeger-LeCoultre retailer
at least once every 2 years, and definitely before any period
in which it will undergo prolonged and / or regular immersion.
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.
