The Longines Spirit Zulu time embodies the brand’s century-long expertise in multi-time zone watches. Its origins and its name derive from the first dual-time-zone Longines wristwatch produced in 1925, which featured the Zulu flag on its dial, a reference to the letter ‘Z’ designating universal time for aviators. Aesthetically, the Longines Spirit Zulu Time stands out for its meticulous workmanship and special attention to detail. It features a bi-directional rotating bezel with ceramic inlay. Each model is equipped with an exclusive Longines calibre with a silicon hairspring, resistant to magnetic fields and COSC chronometer-certified.
