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 (have 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
- restore the time-setting crown and the push-pieces to their normal positions
(or, where applicable, close the compression key) after every manipulation
- rinse the watch with fresh water after use in sea-water.
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 or 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 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
