For nearly a century, LONGINES has accompanied some of the world’s greatest explorers in their conquest of the air, sea and land. The LONGINES Spirit collection brings to life the pioneering spirit that drove these extraordinary men and women to surpass themselves, pursue new ambitions and believe in the impossible. Linking history with innovation, the LONGINES Spirit Chronograph watches take traditional features from aviators' watches and combine them with state-of-the-art horological technologies. All their movements are equipped with silicon balance-springs and are chronometer-certified by the COSC.
