This replica big bang black carbon features a chronograph Big Bang with a carbon-fiber dial and black composite case that pushes Hublot’s material-fusion philosophy into motorsport territory. Carbon fiber on the dial creates a distinctive cross-hatch pattern visible under magnification, and the matte-black case surfaces eliminate any reflective glare that would distract from the technical aesthetic. The chronograph sub-registers at three and nine o’clock sit recessed into the dial plane, and the date aperture at four-thirty follows the standard Big Bang placement. This is one of the more aggressive-looking models in the series, leaning into the performance-material narrative that carbon fiber carries from Formula 1 and endurance racing contexts.

Key Specifications

• Case material: black composite with carbon elements
• Dial: carbon fiber with cross-hatch weave pattern
• Bezel: six H-shaped screws on matte-black surface
• Crystal: sapphire with anti-reflective coating
• Sub-dials: chronograph seconds at 9, elapsed minutes at 3
• Strap: black rubber with carbon-pattern overlay
• Movement: automatic chronograph

The carbon-fiber weave on the dial runs at a 45-degree angle to the horizontal, which is consistent with aerospace-grade layup orientation used in structural carbon panels.

Design & Finishing

Carbon-dial Big Bangs sit in a category between the standard matte-black versions and the skeleton Unico models. The weave pattern adds visual depth that a flat matte dial lacks, but it maintains legibility that open-worked dials sometimes sacrifice. Hublot’s use of carbon fiber reflects the brand’s long partnership with Formula 1, where the material defines both performance and visual identity. The Sang Bleu II in white ceramic takes the opposite approach, using light-colored materials for an art-forward statement. Both live in the Big Bang collection but serve completely different wrist personalities.

On the Wrist

The carbon-composite construction produces a case that runs lighter than steel while maintaining rigidity and scratch resistance. On the wrist, this translates to a watch that wears comfortably through extended sessions without the heft of a precious-metal chronograph. The all-black palette works with nearly any strap or clothing combination, and the carbon dial provides just enough texture to keep the eye engaged without shouting for attention. This replica big bang black carbon delivers a motorsport-influenced Big Bang that prioritizes material credibility over decorative flash.
