Jaeger-leCoultre Master CoMpressor extreMe World Chronograph - User Manual

Introduction
We congratulate you on the purchase of your Jaeger-
LeCoultre watch and thank you for your confidence.
Your innovative Master Compressor Extreme World
Chronograph watch features an instantaneous display
of the 24 time zones, as well as a clever fast strap-change
mechanism to switch from rubber to leather in a moment.
A world première shock absorber system protects the new
automatic chronograph movement in this timepiece from
shocks and vibrations that may be sustained in even the most
extreme conditions.
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,
magnetic 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 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.
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 Extreme World
Chronograph watches are water-resistant to 10 bar/atm. This
property can be identified by the
symbol engraved
on the case-back. This means that you can use your watch
during short swims or when diving in from the edge, but
not from a diving board. Nor should it be used 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.
Furthermore, it is essential to have your watch’s water-
resistance checked by an authorised Jaeger-LeCoultre retailer
at least once every two 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 each of its watches to the rigourous
«1000 Hours Control» test programme. Unique in its kind,
this test consists of 1000 hours of comprehensive, stringent
checks.
