The Longines Spirit Zulu Time typifies the brand’s century-old expertise in timepieces with multiple time zones. Its origins and its name come from the first Longines dual time zone wristwatch manufactured in 1925, which featured the Zulu flag on its dial – Zulu referring to the letter “Z” that designates universal time for aviators. Aesthetically, the Longines Spirit Zulu Time stands out with its meticulous execution and the particular care given to the various details. It features a bidirectional rotating bezel with a ceramic insert. Each model is powered by an exclusive Longines calibre, equipped with a silicon balance-spring, resistant to magnetic fields and chronometer-certified by the COSC.
