Longines introduced the Spirit Zulu Time line to reference the manufacturer's 1925 dual-time model, which featured a Z flag on the dial because early aviators used Zulu time for universal navigation. The brand released this specific L3.802.4.93.6 reference in a 39mm stainless steel case to provide a reduced case size compared to the original 42mm.
The timepiece operates using the COSC-certified caliber L844.4 automatic movement, which achieves a 72-hour power reserve and incorporates a monocrystalline silicon balance spring to reduce magnetic interference. The exterior utilizes a blue ceramic bidirectional bezel and an independent 24-hour hand.
Founded in Saint-Imier in 1832, Longines is one of the most enduring watchmaker, identified by its winged hourglass logo—the oldest registered trademark for a watchmaker in continuous use. The brand was an early pioneer of industrialized watch production, establishing a formidable reputation as a true manufacture capable of producing exceptionally engineered movements.
Longines then took various role as the official timekeeper for championship sports and as an indispensable instrument for the pioneers of aviation, including Charles Lindbergh and Amelia Earhart. Today, as a cornerstone of the Swatch Group, Longines expertly leverages its vast archives, particularly through its celebrated Heritage collection, which offers faithful recreations of its most significant historical references.
