In accordance with the ISO 22810/NIHS 92-20 standard, in order to guarantee
the durability of the watch's characteristics over time and as the water resistance
may be affected by certain activities, it is recommended that the user:
- have the water resistance of the watch checked by an authorised Jaeger-
LeCoultre retailer, in accordance with the recommendations of the Jaeger-
LeCoultre Manufacture and at any event after each opening of the case, in
which case it is advisable to perform an air overpressure test
- check when making the purchase that the strap or 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 nor-
mal position (or, where applicable, close the compression keys) after every
manipulation
- rinse the watch with fresh water after use in sea-water.
Furthermore, it is vital to have the water resistance of your watch checked by
an authorised Jaeger-LeCoultre retailer at least once every two years, and at any
event 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.
