LeCoultre Manufacture and at any event after each opening of the case, in which
case it is recommended that the test be carried out with increased air pressure
- check when making the purchase that the bracelet is suitable for the intended use
- avoid subjecting the watch to excessively abrupt temperature changes
- protect the watch from being dropped or suffering other shocks (having the
watch checked after any violent impact)
- avoid the use of the controls, push-piece or time-setting crown while under
water or before the watch has dried after immersion
- be sure to restore the time-setting crown and the push-pieces to their normal posi-
tion (or, where applicable, close the compression key) after every manipulation
- rinse the watch with fresh water after use in seawater.
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.
Furthermore, it is vital to have your watch’s water-resistance checked by an auth-
orised Jaeger-LeCoultre retailer at least once every two years and, in all cases, 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 internal 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.
