About This Piece

Tonneau Shape & Material Fusion The Spirit of Big Bang Titanium Blue Ceramic showcases Hublot's signature "Art of Fusion" within an ergonomic tonneau-shaped silhouette. By combining a lightweight satin-finished titanium inner case with a vibrant blue ceramic bezel and black composite resin lateral inserts, this 42mm timepiece achieves a striking structural contrast. The multi-component architecture ensures exceptional scratch resistance while maintaining a lightweight and comfortable presence on the wrist. Skeletonized Chronograph Caliber Visible beneath the scratch-resistant sapphire crystal is an intricate skeletonized automatic chronograph movement utilizing the caliber HUB4700 architecture. A high-frequency mechanical engine operating at 5Hz ( $36,000$ vibrations per hour), it delivers precise tracking alongside a 50-hour power reserve. The open-work design neatly integrates the gear train, a date disc window between 4 and 5 o'clock, and sub-dials for hours, minutes, and small seconds. Technical Dial & Sport Ergonomics The transparent sapphire dial features 904L stainless steel stick and dot indices alongside matching hands treated with luminescent material for optimal low-light legibility. Emphasizing its technical, high-performance aesthetic, the watch is paired with a structured black rubber strap that integrates seamlessly into the curved case profile. The strap adjusts for a tailored fit and fastens securely with a 904L stainless steel deployant clasp. Precision Engineering Standards This model stands out through its precise multi-component construction, matching the signature dimensions, thickness, and curves characteristic of the Spirit of Big Bang collection. From the clean execution of the H-shaped bezel screws to the detailed texturing of the dial elements, every physical component is engineered to celebrate contemporary horological design. 2-Year International Warranty All of our Swiss mechanism watches are protected by a full 2-Year International Warranty, ensuring functional reliability, long-term performance, and complete peace of mind with every purchase.
