When Hublot turns its attention to the tourbillon, the result can only be unique. To highlight this emblem of watchmaking expertise, the manufacture has created a skeletonized format of concentric circles around a mechanism placed at 6 o’clock. Equipped with a five-day power reserve, the HUB6016 caliber with manual winding system also stands out with its highly practical and readable power reserve display at 9 o’clock through a disk and five sectors.
