Jaeger-leCoultre Master CoMpressor extreMe W-alarM Introduction Manual

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.
