Following the remarkable success of the CVSTOS CHALLENGE K. KHACHANOV in 2025, Sassoun Sirmakes and Karen Khachanov reunite to push the boundaries even further. What began as an ambassadorial partnership has evolved into a true horological collaboration. Karen Khachanov is no longer a face, he is a driving force behind the vision.

Lighter by 1.5 grams than its inaugural predecessor, this new edition embodies the ultimate balance between minimum weight and maximum strength. The case is crafted from layered carbon fibre, a high-tech composite material distinguished by its exceptional resistance and typical stratified texture, that reveals unique geometrical patterns.

Clad in deep black and displaying a technical inventivness that underscores a maverick style, the tonneau-shaped case frames a beautifully balanced architectural arrangement that draws the eye’s attention towards the in-house mechanical manually wound calibre equipped with a power-reserve of 60 hours. Its dynamic construction reveals a spectacular superimposition of the components, elevated by hand-beveled ruthenium coated bridges that emphasize the skeletonizing of the movement and enhance its intricate spirit of Haute Horlogerie.
