Challenge Jetliner Forged Carbon

Case manufactured with noteworthy new technology
Forged carbon is an advanced technology gaining attention in the automotive and aerospace industries. By casting carbon fiber with random fiber orientation, it overcomes the drawback of conventional carbon fiber, which tends to split along the direction of the pattern. However, it requires casting at even higher temperatures and pressures, and minor shape corrections are difficult due to its extreme toughness. This new "Jetliner" model generously incorporates this challenging-to-manufacture material. Furthermore, Kustos mixes colored glass during the casting process, creating random stripe patterns on the case surface for an accent. This is a new luxury sports model with no compromises in movement or fit.

Challenge Chrono Forged Carbon

The ultimate material fused with a chronograph
This watch is also a model that utilizes forged carbon, fused with the highly popular chronograph function. The process of forging forged carbon under high temperature and pressure can be compared to the process of creating diamonds, and its manufacturing cost is comparable to precious metals.

The forged carbon case, mixed with colored glass to create unique color accents, is literally a black diamond, offering not only toughness but also supreme luxury. The fusion with the intricate chronograph mechanism visible through the see-through dial and case back is irresistible to watch enthusiasts. It truly deserves to be called a cutting-edge timepiece.
