There’s no complication more visually arresting than the tourbillon, and ever since its inventor patented it more than 200 years ago, it’s been fascinating lovers of fine watchmaking with its beauty and enticing them with its rarity. The Palatial Flying Tourbillon Jump Hour adds to the visual dazzle of the tourbillon two additional functions: a jump hour disk, located at 10:00, with an instantaneous jump hour display, and a retrograde minutes counter sweeping across an arc to its right. The translucent colored dial allows the viewer to see the coordinated action of each of these fascinating complications. Movement: Manually Wound Jump Hour and Retrograde Minute Jacob & Co.
