Ulysse Nardin's Executive Skeleton Tourbillon takes the brand's most futuristic design language and opens it right up: the 45mm titanium case is ultra-light on the wrist, and the dial is skeletonized down to a raised rectangular bridge holding oversized Roman numerals, sword hands, and a flying tourbillon spinning at 6 o'clock. This is the Hyperspace treatment, with hand-finished color detailing that gives the openworked movement real depth. Behind it runs an in-house manufacture caliber with a flying silicium tourbillon and a remarkable multi-day power reserve, all visible from both sides through sapphire crystal. Water resistance is 30m and it wears on a leather strap. Brand new and complete with box and papers, this piece joins the Ulysse Nardin Watches at Grand Caliber for the collector who wants a modern tourbillon with genuine architectural presence.
