Hublot Shaped Square Bang Unico Titanium Blue Ceramic 42mm 821.NL.5170.RX - BRAND NEW

The Hublot Square Bang Unico 821.NL.5170.RX represents the pinnacle of the brand's departure from the round-case orthodoxy that dominates haute horlogerie. Introduced as an evolution of the iconic Big Bang DNA, the Square Bang Unico reframes Hublot's design language inside a bold 42mm square case, delivering an immediately recognizable silhouette that commands attention on the wrist without abandoning the technical ambition the brand is celebrated for.

At the heart of this reference is the choice of materials. The 42mm case is crafted from satin-finished and polished titanium — a metal prized in watchmaking for its exceptional strength-to-weight ratio and its remarkable comfort during extended wear. Titanium's natural hypoallergenic properties and resistance to corrosion make it a thoroughly practical choice for a watch worn as boldly as it is admired. The result is a substantial presence that nevertheless feels effortlessly light on the wrist.

The blue ceramic bezel elevates the 821.NL.5170.RX beyond a purely monochromatic study. Ceramic is scratch-resistant, colorfast, and holds its luster far longer than conventional metal or PVD treatments — qualities that matter when a bezel is as architecturally prominent as it is on the Square Bang. The blue tone is deep and rich, coordinating beautifully with the blue index dial beneath it. Index hour markers on the dial maintain legibility while contributing to the watch's refined, uncluttered aesthetic.

Powering the Square Bang Unico 821.NL.5170.RX is Hublot's in-house Unico automatic flyback chronograph movement, an integrated caliber developed entirely within the manufacture. The Unico movement is widely respected among collectors for its column-wheel control, lateral clutch, and the fact that it enables Hublot to display the chronograph mechanism through a skeletonized or exhibition-style architecture — a hallmark of the Square Bang's dial design. The rubber bracelet, a Hublot signature since the original Big Bang, grounds the watch in the brand's sport-luxury philosophy and ensures a secure, comfortable fit for active wear.
