Introduction
Congratulations on the purchase of your Jaeger-LeCoultre
watch, and thank you for your confidence.
Produced in partnership with the elite divers of the American
armed forces, the United States Navy SEALs, this new genera-
tion of diving watches is distinguished by a case with extreme
high-pressure resistance. A genuine professional diving tool
inspired by the equipment of this special unit, the Master
Compressor Diving Alarm Navy SEALs offers perfect read-
ability thanks to oversized and luminescent-coated numerals,
indexes and hands. The unidirectional bezel enables elapsed
diving times to be calculated via its luminescent reference
triangle.
Please check through the operating instructions for your
Jaeger-LeCoultre timepiece: we hope that you will be very
happy with it.
Accuracy
Accuracy is ensured by the balance, which completes
28,800 vibrations per hour.
Despite all the care with which the Manufacture
Jaeger-LeCoultre master watchmakers have made and
assembled your watch, its accuracy is subject to the influence
of gravity, magnetic fields, impacts and ageing of the oils.
Watch accuracy is measured by rate regularity in a variety
of positions.
The nature of your constitution or lifestyle may lead to slight
irregularities. If you observe irregular running of your watch,
you are advised to take it to an authorised Jaeger-LeCoultre
retailer, who will make any necessary adjustments.

Water-resistance
Jaeger-LeCoultre watches are water-resistant to 3, 5, 10, 20, 30
or 100 atm, depending on the model (see technical specifica-
tions). This property can be identified by the
engraved on the case-back. This means that your timepiece
has been tested to an immersion pressure equivalent to 30,
50, 100, 200, 300 or 1000 metres, according to the number
of atmospheres shown beside the aforementioned symbol
(1 atm = 10 metres).
You can use your watch while swimming or diving from the
edge, but not from a diving board. Please also note that
leather straps are not suited to water sports.
It is essential to have your watch's water-resistance regu-
larly checked by an authorised Jaeger-LeCoultre retailer, and
definitely before a period of intensive use.
The «1000 Hours Control» test
by Jaeger-LeCoultre
Jaeger-LeCoultre subjects each of its watches to the rigour-
ous "1000 Hours Control" test programme. Unique in its kind,
this programme consists of 1000 hours of comprehensive,
stringent checks.
The "1000 Hours Control" seal or marking affixed or
engraved on the back of your watch certifies that it has
undergone this observation programme in our laboratories
and has passed all the tests, relating to rate regularity, tem-
perature and atmospheric pressure, resistance to impacts
and magnetic fields, as well as water-resistance. Your watch
is therefore capable of withstanding the trials awaiting it in
everyday life when you wear it on your wrist.
The criteria of the "1000 Hours Control" programme
go far beyond the official timekeeping test stand-
ards, which concern only part of the movement.
Jaeger-LeCoultre tests not only the movement before casing
it within the watch, but also the watch as a whole.
