Two Time Zones. One Certified Chronometer.

In aviation, Zulu Time is the universal standard — the single reference point that keeps pilots, controllers, and crew synchronized across every time zone on earth. The Longines Spirit Zulu Time Black Dial (L3.802.4.53.6) honors that tradition with a true GMT complication, a COSC-certified chronometer movement, and the bold aviation aesthetic that defines the Spirit collection. This is a pilot's watch built for the modern world traveler.
