Weighing just 50 grams, it combines a layered carbon case with the in-house openworked calibre CVS610, delivering a 60-hour power reserve. Finished with a high- resistance Cordura® technical strap, its dynamic DNA moves effortlessly from case to wrist.
• Lightness. Strength. Precision.
A winning set
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 simply a face — he is a driving force behind the vision.
Resonating worldwide among collectors and connoisseurs, the first edition was met with extraordinary enthusiasm and is now entirely sold out.
Building on this momentum, this powerful combination of expertise has led to the creation of a new limited edition of the CHALLENGE K. KHACHANOV — a timepiece conceived with the same discipline, precision and relentless pursuit of performance that define champions.
• Where champion spirit meets horological vision.
50 grams of pure technical mastery
Lighter by 1.5 grams than its inaugural predecessor, this new edition embodies the ultimate balance between minimal weight and maximum strength. The case is crafted from layered carbon fibre — a high-tech composite material distinguished by exceptional resistance and a characteristic stratified texture that reveals unique geometric patterns.
Clad in deep black and showcasing a technical inventiveness that underscores its maverick spirit, the tonneau-shaped case frames a beautifully balanced architecturalcomposition. The eye is naturally drawn toward the in-house, manually wound mechanical calibre, offering a 60-hour power reserve.
Its dynamic construction reveals a striking superimposition of components, enhanced by hand-bevelled, ruthenium-coated bridges. These details accentuate the skeletonized architecture of the movement and elevate its intricate Haute Horlogerie character.
• Minimum weight, maximum strength.
Technical DNA from case to wrist
Moving beyond rubber or alligator, the CHALLENGE K. KHACHANOV is fitted with a high- performance Cordura® technical textile strap, engineered for extreme resistance, lightweight durability and uncompromising comfort.
Conceived for action and performance, it extends the timepiece’s technical DNA seamlessly from case to wrist.
• Performance extended to the wrist.
