HYSEK IO Skeleton Tourbillon 49mm


The IO Skeleton Tourbillion marks a definite evolution of the IO line. The codes on which was founded the collection; an audaciously designed case, classic yet modern, boosted by ample circular curves are blended henceforth with a strong desire of purity.

Once more HYSEK applies all its creative force and its watchmaking know- how in creating the new IO Skeleton Tourbillon.

« Oversized », the new IO offers a generous translucent dial allowing to admire its totally skeletonized calibre. Eminently romantic and aerial, this new model of the IO line, distinguishes itself from previous creations of this collection.

Confined in a set of layered sapphire glasses, the manufactured calibre seems to hang above the emptiness thus projecting in levitation the pieces of which it is composed.  Proof of Manufacture Hysek’s unique creativity, this extraordinary timepiece in rose gold is  brought to move by an automatic tourbillon as well as a calibre made up of 183 components and delicately adorned with a Rose des Vents pattern.

Just like a rain of twinkling stars, the flange entirely set with diamonds, dominates the unveiled mechanism. And yet comes another technical achievement: every time the crown is wound up, the flange ingeniously fills with life and gravitates around the mechanism while making its 90 black diamonds setting dance, illustrating the endless minutes’ run in the hour. Suspended in time and in space, the index 1-5-7-11 specific to the brand, languorously give rhythm to the time that passes away.

Ethereal and transparent, the dial traps precious diamond dust, like the infinite number of stars that fill the sky.  
To please mechanical complications enthusiasts, Hysek has also launched an uncluttered version, characterized by the delicacy of a case proudly unveiling its extremely precise skeleton movement from which only the most essential components have been retained.

Larger and finer than the previous IO creations, the new IO Skeleton, will seduce the connoisseurs by its sober characteristics, uncluttered and fundamentally differentiator. 

The IO 49mm Skeleton Tourbillon is available in a limited series of 8 pieces.
