class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe Spirit Zulu Time connects modern Longines directly to the brand’s history of multi-time-zone watches.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eLongines traces the Zulu Time name to a dual-time-zone wristwatch it produced in 1925, whose dial incorporated the Zulu flag. “Zulu” refers to the letter Z, historically used by aviators to designate universal time.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe modern Spirit Zulu Time translates that history

bezel, silicon balance spring, and practical 39 mm proportions, helped make the Zulu Time one of the most important recent additions to Longines’ sports-watch catalog.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eDesign Provenance\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe 39 mm version is particularly successful because the proportions allow the dial and bezel to remain visually balanced.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe anthracite dial provides a softer backdrop than conventional black, while the green ceramic bezel
