1000 Hours Control" Test - Jaeger-leCoultre MASTER GRANDE TRADITION Manual

- 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 significant risk of impact, such
as windsurfing 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 certifies 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 and resistance to shocks and magnetic
fields, 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.
