Historically, Longines has accompanied legendary pioneers as they conquer air, land and sea. Today, the winged hourglass brand has drawn inspiration from this heritage to create Longines Spirit, a collection with an impeccable pedigree. This collection links history with innovation by combining references to the glory days of aviation with present-day aesthetic and technical requirements. These resolutely contemporary timepieces are a testimony to the pioneering spirit that has inspired the brand since its earliest days. A glowing tribute to these exceptional men and women who, by a record, an exploit or a display of courage, have left their mark on history - pushing new generations to surpass themselves.
