Longines extends five-year warranty to certain models

Longines announced that it has extended its warranty to five years on all models using the antimagnetic silicon balance-spring, including all the timepieces of the new Longines Spirit collection. Among others, all models of the new collection are fitted with cutting-edge movements that include a silicon balance-spring. Silicon is a lightweight material resistant to corrosion and unaffected by normal temperature variations, magnetic fields, and atmospheric pressure – all of which enhance a watch’s accuracy and longevity. All watches of the new collection are independently verified by their COSC certification by the Official Swiss Chronometer Testing Institute as chronometers.
