Introduction
We congratulate you on the purchase of your Jaeger-
LeCoultre watch and thank you for your confidence.
Your Master Compressor Chronograph watch asserts itself in
the sporting world thanks to the first automatic chronograph
movement produced by Jaeger-LeCoultre. The patented
compression key system has been adapted for integration
into the chronograph pushpieces. The inner bezel ring displays
the tachometric scale which enables measurement of average
travelling speeds.
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.
