Montblanc Laboratory Test 500

The master watchmakers of the Montblanc Manufactures in Villeret and Le Locle create genuine works of
art of great complexity from hundreds of tiny components.
Slowly and meticulously assembling delicate movement parts such as balance-springs, jewels, pallet-forks and
pallet-stones, they bring these extremely precise timepieces to life.
To ensure that their commitment and painstaking work is reflected in the lasting quality of their creations,
each watch is subjected to a rigorous programme of tests: the Montblanc Laboratory Test 500.
Over nearly three weeks, 500 hours to be precise, the watches are tested under various conditions that
simulate those that the watch will encounter on its owner's wrist: daily wear, repeated adjustments by use of
the crown, different climatic conditions and both normal and more brutal use of the various functions.
Only after passing this test, which is attested by the Montblanc Laboratory Test 500 certificate, can the
watches leave the Manufacture.
Corresponding perfectly to Montblanc's rigorous quality standards, they are assured of long lives on their
owners' wrists.
The delivery of a watch is only possible once the quality assurance team of Montblanc Montre S.A. in Le
Locle has been satisfied that it meets Montblanc's strict quality standards.
Every watch that passes the Montblanc Laboratory Test 500 is issued with an individual certificate.

Water-Resistance

Water splashes
Rain
Strong exposure to water
Immersion in water
Free diving
The water-resistance of a Montblanc watch is guaranteed to a pressure limit that is specified in bars. Except
for watches guaranteed to a pressure of 10 bars or more, the indication in metres does not correspond to
a diving depth but refers to the pressure at which the water overpressure test was conducted. Furthermore,
the water-resistance of a Montblanc watch may be affected by sudden or repeated water pressure changes
encountered by surface swimmers, by high water temperatures, or by sudden changes in temperature.
Montblanc recommends, therefore, that each Montblanc watch be pressure-checked on a yearly basis by a
Montblanc Service Centre or an authorised retailer.
