Ulysse Nardin’s Grand Deck Marine Tourbillon model retrograde minutes display takes the form of a boom. On the dial, hand-crafted wood marquetry evokes a ship’s deck, while the time display is original and creative: a boom pulled by super-strong nanowires indicates the minutes, while the hours are displayed on two concentric disks. The patented device, which is regulated by a second barrel, also incorporates a majestic tourbillon. The case is white gold, fluted bezel. The bracelet is leather with a folding buckle.
