Hublot Square Bang Unico White Ceramic 42mm 821.HX.0170.RX

The Hublot Square Bang Unico 821.HX.0170.RX represents one of the most architecturally daring statements in contemporary luxury watchmaking. Where most high-end sports watches default to round cases, Hublot committed fully to a squared silhouette that references avant-garde design without sacrificing wearability. At 42mm, the case occupies the wrist with commanding presence while remaining versatile enough for a wide range of wearers. The white ceramic construction gives the watch an almost sculptural quality, and the brand's use of high-tech ceramic — prized for its hardness and resistance to scratching and discoloration — ensures that this striking appearance endures over years of wear.

The Square Bang line itself is a natural evolution of Hublot's iconic Big Bang DNA. Launched as Hublot pushed beyond the boundaries of conventional case geometry, the Square Bang marries the brand's signature porthole-lug design language with a four-cornered form that feels genuinely futuristic. The 821.HX.0170.RX in white ceramic is among the most visually arresting executions of this concept: the cool, bright case material contrasts sharply with the deep black dial, creating a graphic, high-contrast aesthetic that photographs beautifully and reads with equal clarity in person.

The dial of the 821.HX.0170.RX presents clean black with index hour markers, offering legibility without visual clutter. Hublot's approach to the dial here is disciplined — the indexes do the work of telling time efficiently while the overall composition lets the geometric architecture of the case dominate the conversation. The ceramic bezel frames the dial with structural consistency, keeping the material story unified from lug to crystal.

Powering this reference is Hublot's in-house Unico movement, an automatic caliber that the brand developed to bring genuine manufacture credibility to its collection. The Unico is well regarded among Hublot enthusiasts for its robust construction and the visual interest it brings to skeletonized and open-worked designs across the Big Bang and Bang families. In the 821.HX.0170.RX, its presence underpins the watch's legitimate claim to high-horology credentials rather than relying solely on aesthetic spectacle.

The rubber bracelet is a characteristically Hublot choice — the brand pioneered the fusion of precious or high-tech case materials with rubber straps in luxury watchmaking, and it remains a signature of the house. On the Square Bang, this combination of cold white ceramic and supple rubber reads as both sporty and refined, making the 821.HX.0170.RX suitable for everything from business-casual settings to weekend wear. The bracelet also contributes meaningfully to comfort on the wrist, providing flexibility that complements the rigid geometry of the case.
