The LONGINES Spirit Zulu Time embodies the brand’s century-long expertise in multi-time zone watches. Its origins and name come from the first LONGINES dual-time zone wristwatch produced in 1925, which featured the Zulu flag on its dial, a reference to the letter “Z” that designates 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 a ceramic inlay. Each model is equipped with an exclusive LONGINES calibre, with a silicon balance spring, resistant to magnetic fields and chronometer certification from the COSC.
