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. 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 the 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. To ensure that their commitment and painstaking work are reflected in the lasting quality of their creations, each watch is subjected to a rigorous programme of tests: the Montblanc Laboratory Test 500. Every watch that passes the Montblanc Laboratory Test 500 is issued with an individual certificate. 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 adjustment by use of the crown, different climatic conditions and both normal and more brutal use of the
various functions.
