Longines · Family: Spirit
The Longines Spirit Zulu Time ref. L3.812.4.53.6 is a true GMT in 42 mm steel with an independent local-hour jump operated from the crown alone, no extra pusher, and COSC chronometer certification. As of July 21, 2026, Cazador does not yet hold enough market data (n<5) to publish a reliable price range for this reference. Its standout feature: setting the local hour without ever touching the GMT reference hand, unusual for a true GMT.

Longines builds its brand narrative on a genuine heritage in aviation and exploration dating back to the 1920s and 1930s. The Swiss house equipped aviation pioneers and navigators with precision instruments: the hour-angle watch developed with Charles Lindbergh in 1931 and the second-setting watch developed with US Navy Commander Philip Van Horn Weems in 1935 are two documented milestones of that collaboration between watchmaking and aerial-navigation instrumentation. The Spirit collection, introduced in 2020, was conceived as a direct tribute to that legacy: a rugged tool-watch aesthetic with a domed sapphire crystal, coin-edge bezel, and a visual identity that recalls early-to-mid-20th-century onboard instruments. In 2022 the collection gained a GMT complication under the name Zulu Time, referencing the military and aeronautical term for UTC/Greenwich time used by pilots and navigators to coordinate independently of local time zones [UNVERIFIED: exact commercial launch date of this specific reference not confirmed against a primary source]. The L844.4 caliber fitted to this reference is a true GMT movement: the 24-hour hand tracks a fixed second time zone while the local-hour hand can jump forward or backward one hour at a time without stopping the watch or disturbing minutes or seconds. What stands out is the setting mechanism: most true GMTs on the market control that jump through an additional case pusher; the Spirit Zulu Time performs it by pulling the crown itself, simplifying the case and reducing potential water-ingress points.
Zulu Time is the military and aeronautical term for UTC/Greenwich time, used by pilots and navigators to coordinate without depending on local time zones. Longines revives that vocabulary from its flight-instrumentation heritage to name this reference's GMT complication.
It is a true GMT: the 24-hour hand tracks a fixed time zone while the local hand can jump forward or backward one hour at a time without stopping the watch or affecting minutes and seconds. That genuine independence of the local hand is what defines a true GMT versus a merely indicative one.
Cazador currently lacks sufficient market data (n<5 observations) for this reference to publish a reliable range. Once we accumulate verified transactions or listings, this block will show price, 12-month trend, and last-updated date.
The local-hour jump is set by pulling the crown, with no extra case pusher, which is uncommon among true GMTs in this category. Fewer case openings typically means better water-tightness and simpler long-term maintenance.
It runs the Longines L844.4 caliber, automatic, based on the ETA A31.L11 and COSC chronometer certified. Being built on a widely deployed ETA base within the Swatch Group, it benefits from good service and parts availability through the official Longines network.
The Spirit line is typically rated at 100 m water resistance [UNVERIFIED: figure not specifically confirmed for this reference], enough for recreational swimming, but it is not designed as a technical dive watch.
Approximately 72 hours per catalog specification [UNVERIFIED: figure not independently verified], enough to leave it unworn over a full weekend without needing to reset time and date when picking it back up.
