This replica big bang 1171 42mm identifies the 441.CI.1171.RX, a black ceramic Big Bang in the more compact 42mm case size that Hublot introduced to broaden the collection’s wrist compatibility. The 42mm diameter sits between the original 44mm and the ladies’ 38mm versions, and the ceramic construction keeps the case weight noticeably lower than an equivalent steel piece at this size. The “CI” in the reference confirms full ceramic build with a micro-blasted surface that absorbs light rather than reflecting it, producing a stealth-black appearance that reads as monolithic from any viewing angle.

Case & Movement Specs

• Case diameter: 42mm
• Case material: black ceramic, micro-blasted
• Reference: 441.CI.1171.RX
• Bezel: black ceramic, six H-shaped titanium screws
• Dial: matte black with applied luminous markers
• Crystal: sapphire with anti-reflective treatment
• Strap: black lined rubber with deployant buckle
• Movement: automatic

The 42mm case maintains the same angular lug geometry and H-screw bezel layout as the larger 44mm and 45mm variants, scaled proportionally rather than simply shrunken.

Caliber Breakdown

The automatic movement in the 441.CI delivers standard time-and-date functionality through a proven caliber housed behind a solid caseback. The screw-down crown at three o’clock matches the case material in black, blending into the side profile rather than creating a metallic interruption. Ceramic cases demand specialized gasket engineering because the material does not flex under pressure the way metals do, requiring rigid sealing at every junction point. For a contrasting take on the Big Bang at scale, the Sang Bleu II in blue at 45mm shows how collaborative design transforms the same platform entirely. Both sit within the Big Bang family but target different buyer profiles.

How It Compares

The 42mm ceramic Big Bang appeals to buyers who find the 44mm too large for their wrist circumference but still want the full Big Bang design language intact. Ceramic at this diameter produces a watch that disappears under a shirt cuff while retaining the bold case shape when exposed. The combination of lightweight material and moderate sizing makes this among the most comfortable daily-wear options in the entire collection. This replica big bang 1171 42mm condenses the Big Bang’s visual identity into a more wrist-friendly package without compromising any structural element.
