The Longines Spirit Zulu Time 42 mm is a modern pilot’s GMT watch that merges heritage design with technical precision. It features a 42.00 mm stainless steel case paired with a black ceramic bezel insert. The dial is matte black, with applied Arabic numerals and silvered polished hands. A central GMT hand provides a second time zone indication. The watch is driven by the automatic calibre L844.4, which offers up to 72 hours of power reserve and includes a silicon balance spring. The watch is water resistant to 10 bar (100 m), and has a bi-directional rotating bezel, screw-in crown, and scratch-resistant sapphire crystal with anti-reflective coatings. It is delivered on a brown leather strap with a double-security folding clasp and micro-adjustment system.
