THE QUALITIES

OF MECHANICAL

WATCHES AND

HOW TO

PRESERVE THEM

Why do Longines’ watchmakers include watches fi tted with mechanical movements in their collections?

There’s a simple answer: watches fi tted with a state-of-the-art hand-wound or self-winding mechanical movement provide all sorts of satisfaction that no other type of timepiece can match. Of course more accurate technology is easy to fi nd: quartz resonators for instance, but nothing beats a mechanical watch for pleasure pure and simple. Incorporating countless technical improvements, today’s mechanical movements qualify as marvels of inspired ingenuity, born of centuries of fascinating history and the patient workmanship of some of the world’s fi nest craftsmen. You need only observe a movement’s intricate mechanism and rhythmically moving parts, the beauty and fi neness of its components fashioned out of steel as well as various complex alloys and even gold to understand that you are looking at a shining example of applied intelligence, brought to life by Nature’s most versatile tool, the craftsman’s hand. And what’s more, the hand- wound or self-winding mechanical movements fi tted in Longines’ latest timepieces are precise to within a few seconds a week, which is more than enough for the demands of everyday life !
