The Zulu Time name reaches back to Longines' first dual-time-zone wristwatch of 1925, and the 39 mm case makes the modern version the most wearable GMT in the Spirit line. Inside is the calibre L844.4 with a silicon balance-spring, a 72-hour power reserve, and COSC chronometer certification. A bidirectional ceramic bezel, a screw-in crown, and 10 bar of water resistance cover the practical side; the five applied stars and anthracite dial cover the rest. For the frequent traveler, it is a mechanical GMT sized for daily wear rather than the cockpit alone.
