The new IO Skeleton Central Tourbillon features an entirely different design compared to its predecessor, further highlighting its Central Tourbillon. In this new, limited edition of just 88 pieces, skeletonisation and transparency take pride of place, benefiting from innovative metallisation and openwork techniques.
The HW22 caliber with which the piece is fitted allows the central tourbillon to remain at the heart of its identity. Hysek also painstakingly searched for the perfect way to arrange the hours and minutes around it; indeed, very few watches feature layouts around a central tourbillon, and even fewer use a flying tourbillon do so.
The central tourbillon is the dominant feature in the composition, and very much sets the tone of the piece. Fully visible, without any obstacles, it is hand-finished and features a “flying” design – this means it has a cage held in place only by its lower bridge, with no upper bridge. This rare, authentic Haute Horlogerie complication adds a sense of lightness to the piece, further enhanced by the skeletonisation of the plate.
This exercise in skeletonisation has also been extended to the entire movement. Not satisfied with simply making the components openwork, Hysek has redesigned their shape and location in order to have a caliber that leaves as much room as possible for light to shine through, resulting in a completely new arrangement. Adopting the same approach to the final aesthetic appearance, Hysek has also designed hours and minutes discs that feature their own special openwork, revealing a movement that has been refined to its simplest expression.
A tiered time display is arranged around this flying tourbillon. The time is read intuitively, even as the user’s gaze is naturally drawn towards the tourbillon. The hours window is displayed at 12 o’clock, and denoted by a luminous triangle, the bottom of which opens out naturally towards the minutes. A second luminous marker indicates the 60 minutes as they pass by in rotation.
The architecture of this composition is unique – not only for Hysek, but probably in watchmaking as a whole. Not only that, the hours and minutes discs are fully skeletonised. In an unusual approach, the figures used do not rest on a translucent surface. Instead, they have been cut out one by one, and are literally suspended in mid-air, held in place only at the top. The hours disc is rotated by the outer rim of the piece, while the minutes ring is held in place by the four golden arms forming the structure of the watch.
Connoisseurs of the manufacture will recognise their hallmark positioning at 1, 5, 7 and 11 o’clock–Hysek’s own four cardinal points, used in the layout of most of its creations. To further aid time-telling, Hysek has added still another touch: each figure is coated with blocks of SuperLumiNova, each individually moulded to the nearest micron. The result is a far cry from standard-fare luminous coating added as an additional layer: the technique uses face-fixed blocks, which are denser and produce far better brightness.
For this limited edition of just 88 watches, Hysek has developed an exclusive finish. The aim is to enhance and amplify the tourbillon movement, the entire focus of this new IO. The upper sapphire crystal is decorated with a circular metallisation pattern that appears to emanate directly from the tourbillon, thus heightening its visual impact. To maximise the effect, Hysek has also removed the micro-rotor from its caliber, offering the most unobstructed view possible of the skeletonisation.
At 12 o’clock, Hysek has crafted a bespoke blue section, providing a backdrop against which the minutes stand out in excellent contrast. To maintain a coherent style effect, the same blue is also to be found on each of the 14 blue-tinted screws visible on the dial, in the finest Haute Horlogerie tradition, as well as being used for the “Hysek” name.
The new IO Tourbillon Central Squelette is 45 millimetres in diameter, boasts a 42-hour power reserve, and comes in an 18-carat rose gold case featuring three-clawmark lugs, one of the manufacturer’s signature touches.
