This timepiece is inspired by the design language of Hublot, continuing the Spirit of Big Bang chronograph series with a strong focus on racing-inspired aesthetics and modern skeleton watch engineering.
The watch features a 42mm case constructed from a combination of high-performance ceramic and titanium materials. This multi-material structure enhances durability while maintaining a lightweight wearing experience. The tonneau-shaped silhouette follows the signature design language of the Spirit of Big Bang collection.
A sapphire crystal with anti-reflective treatment is used to improve clarity and reduce glare, ensuring strong legibility under different lighting conditions. The case architecture integrates H-shaped structural screws, reinforcing the industrial and technical identity of the series.
The dial is fully skeletonized, exposing the internal mechanical architecture and emphasizing depth, transparency, and structural layering. The chronograph sub-dial layout is designed for functional readability while maintaining visual balance within the open-work composition.
The watch is powered by a HUB4700-inspired automatic chronograph movement, operating at 28,800 vibrations per hour with an approximate 45-hour power reserve. The movement focuses on stable chronograph performance and visually engaging mechanical motion.
A quick-release rubber strap ensures flexibility, comfort, and durability, paired with a folding clasp for secure wearing and ease of use.
Overall, this model highlights ceramic-titanium construction, skeleton chronograph mechanics, and motorsport-inspired design language, delivering a bold and technically expressive luxury sports watch.
