Hublot Big Bang Unico Bi-Retrograde Chronograph 413.OM.1128.RX Black Dial Black Ceramic Bezel & Rose Gold Case Rubber 45mm BRAND NEW

The Hublot Big Bang Unico Bi-Retrograde Chronograph 413.OM.1128.RX represents one of the most visually dramatic executions of Hublot's storied Big Bang platform. Introduced as part of the Unico family — a line defined by in-house manufacture movements and skeleton-influenced architecture — this reference pairs an opulent 45mm rose gold case with a confrontational black ceramic bezel and an all-black rubber strap, creating a tension between luxury and sport that is entirely Hublot's own.

The dial of reference 413.OM.1128.RX is finished in black and populated with clean index hour markers that allow the retrograde chronograph subdials to read with complete clarity. Where a conventional chronograph sweeps a central seconds hand in a full circle, the bi-retrograde complication routes elapsed time along two arcing retrograde displays, each hand traveling its arc before snapping instantaneously back to its start position. This mechanical theater elevates the chronograph from a practical tool to a kinetic spectacle that rewards the wearer every time the pusher is engaged.

At the heart of this watch is a Hublot Unico manufacture automatic movement. The Unico caliber was developed entirely in-house by Hublot and was a landmark moment for the brand, demonstrating genuine manufacture credentials. The movement's skeletonized architecture is visible through the dial and caseback, giving the wearer direct visual access to the intricate lever, column-wheel, and gear-train choreography that orchestrates the bi-retrograde function. For a collector who wants a chronograph with intellectual as well as aesthetic depth, this architecture is genuinely satisfying.

On the wrist, the 45mm rose gold case commands immediate presence. The alloy itself carries a warm, distinctly luxurious hue that contrasts beautifully against the matte black ceramic bezel and the supple black rubber strap. Hublot's signature porthole-inspired case shape, with its twelve H-shaped titanium screws around the bezel, frames the dial like a porthole and gives the watch its instantly recognizable silhouette. The result is a piece that sits at the intersection of high horology and contemporary design — appropriate for black-tie occasions and bold enough to anchor a casual ensemble.

The Big Bang Unico Bi-Retrograde in rose gold has attracted collectors who appreciate complications that go beyond the conventional, and reference 413.OM.1128.RX is particularly sought after for its black ceramic bezel and black rubber configuration — arguably the most versatile and wearable expression of the rose gold case variant. Brand-new examples in full set condition are increasingly difficult to source, making this an opportune moment for a serious collector or first-time Hublot buyer to secure one.
