Following the success of the 2025 CVSTOS Challenge K.Khachanov, Sassoun Sirmakes and Karen Khachanov reunite to push horological boundaries. Moving beyond ambassadorial duties, Khachanov now drives the creative vision. The first edition’s worldwide acclaim set the stage for a new limited edition: the Challenge K. Khachanov Carbon. Featuring a multi-layered, three-dimensional dial with hand-beveled ruthenium-coated bridges, the timepiece showcases skeletonized movement and Haute Horlogerie craftsmanship. Weighing 50 grams—1.5 grams lighter than its predecessor—the layered carbon fiber case balances minimal weight with maximum strength, highlighting intricate patterns and superior structural performance.
