You may use your watch during short swims and when jumping in from the edge of a
swimming pool, but not from a diving board. Your watch must not be used for scuba
diving, nor for sports involving signifi cant risk of impact, such as windsurfi ng or water-
skiing. Also note that leather straps are not suited to aquatic activities.
It is vital to have the water resistance of your watch checked by an authorised Jaeger-
LeCoultre retailer before any period during which it is liable to undergo prolonged
and/or regular immersions.
“1000 Hours Control” test
Jaeger-LeCoultre submits all its watches to the stringent “1000 Hours Control”, a
unique battery of comprehensive and rigorous tests lasting a full 1000 hours.
The “1000 Hours Control” seal or legend placed or engraved on the back of your
watch certifi es that the latter has undergone this programme of observation in
our laboratories and has successfully passed all the tests relating to regularity
of rate, temperature, atmospheric pressure, resistance to shocks and magnetic
fi elds, as well as water-resistance trials. Your watch is thus capable of withstanding
the daily stresses and strains that await it when worn on your wrist.
The criteria of the “1000 Hours Control” programme considerably exceed the
standards of offi cial timing tests, which deal only with part of the movement.
Jaeger-LeCoultre tests not only the movement prior to its being cased up in the
watch, but also the watch as a whole.
