Heritage Collection was launched for celebrating Longines free-spirited discoveries in the world of adventures, aviation and under water exploits, thus creating history in the world of horology. Longines is acknowledged for introducing technologies, which have changed the face of the watchmaking industry and the Heritage collection is a tribute to such designers. The Heritage collection truly denotes quintessence of classism. The Longines Heritage L4.785.8.73.2 has an automatic movement with 38 hours of power reserve.
