About This Watch

The Hublot Square Bang Unico King Gold with integrated bracelet is the most luxurious expression of Hublot's square-cased chronograph — a statement piece rendered entirely in the brand's proprietary 18-karat King Gold alloy. Every visible surface, from the square case and eight-screw bezel to the integrated bracelet links, radiates the warm, enduring rose hue that distinguishes King Gold from conventional rose gold. The platinum enrichment in King Gold's alloy ensures this color will not fade or oxidize over time, maintaining the watch's appearance for decades. The integrated King Gold bracelet with angular links complements the square case geometry, creating a cohesive design language that flows from bezel to clasp. At 265 grams, this is a substantial piece — the weight of solid gold combined with the angular case creates a commanding wrist presence that is impossible to ignore. Inside, the HUB1280 manufacture flyback chronograph delivers serious mechanical credentials with its column-wheel mechanism and 72-hour power reserve, visible through the skeletonized dial. The eight H-shaped King Gold bezel screws — two at each corner — create a visual pattern unique to the Square Bang, distinguishing it from both the round Big Bang and the tonneau Spirit of Big Bang. This reference represents the ultimate convergence of Hublot's design ambition and material expertise: a square chronograph in precious metal that challenges every convention of what a luxury sport watch should look like.
