And these exceptional timepieces, whose movement includes a monocrystalline silicon balance wheel with unique properties, certainly have no shortage of arguments. For the first time, Longines receives the "chronometer" certification from the institute of Contrôle officiel suisse des chronomètres (COSC), a title conferred on all creations in the Record collection.
