This replica Big Bang 1171 diamond takes the Unico platform and surrounds it with factory-set stones on both the bezel and lugs, transforming a sport chronograph into something considerably more ornate. The 441.NX.1171.RX.1104 pairs a titanium case with round brilliant diamonds set in a single row around the bezel perimeter. At 42mm, this is the more compact Hublot Unico sizing, bringing the skeletonized dial and column-wheel chronograph into a diameter that works on a wider range of wrist sizes.

Titanium keeps the 42mm case lightweight despite the added mass of the diamond setting. The brushed titanium surfaces contrast with the polished stone bezels, creating a deliberate interplay between matte industrial finishing and jewelry-grade elements.

Design & Finishing

Diamond-set Big Bang references walk a specific line between sport watch and jewelry piece. The round brilliants follow the bezel contour without disrupting the signature six-screw attachment points, so the H-shaped screws remain visible between stones. Through the skeletonized dial openings, the column wheel and chronograph mechanism operate on display. The 42mm diameter makes this noticeably more wearable than 45mm diamond references, which can push into statement territory. Compare this titanium-diamond combination against the 45mm 411.OM.1180.RX in matte ceramic for the opposite aesthetic approach. Both options sit in the Big Bang catalog but serve completely different styling intentions.

On the Wrist

At 42mm, the diamond-set Unico avoids the visual bulk that larger gem-set watches sometimes carry. Titanium construction means the watch feels proportionally light for its apparent richness, a balance that heavier gold-and-diamond combinations struggle to achieve. The rubber strap keeps the overall profile athletic, anchoring the piece to its sport watch origins even as the diamond bezel elevates it. Evening wear, tailored suiting, and smart-casual settings all accommodate this reference comfortably. This replica Big Bang 1171 diamond demonstrates that the Unico skeleton chronograph gains an entirely different audience when dressed in stones and scaled to a moderate diameter.
