Details & Specifications
Description:
The Longines Spirit Zulu Time reference L3.812.4.50.6 celebrates the brand's century-old expertise in dual time zone timepieces, tracing its lineage back to Longines' first GMT wristwatch made in 1925, which featured the Zulu flag on its dial. The 42mm stainless steel case is finished with a bidirectional rotating bezel featuring a ceramic insert, its 24-hour scale split between matte and polished black to distinguish day from night hours.
The matte black dial creates a striking contrast with the rose-gold-coloured hands and applied Arabic numeral indexes, treated with Swiss Super-LumiNova, and is further distinguished by five stars positioned above the 6 o'clock marker, with a discreet date window and "1925 – 2025" engraved in tone-on-tone finish. Powered by the exclusive Longines Calibre L844.4, a self-winding movement with a silicon balance-spring for enhanced resistance to magnetic fields, the watch delivers up to 72 hours of power reserve and is chronometer-certified by the COSC. The watch is fitted on a matching stainless steel bracelet with a double safety folding clasp and push-piece opening mechanism.
