The Hublot Big Bang Unico 411.MX.1138.RX is among the most commanding expressions of the Big Bang family, combining a 45mm yellow gold case with a fully skeletonized dial that lays the movement's architecture bare for all to admire. Arabic numerals and index hour markers are integrated directly into the open dial, creating a layered, three-dimensional reading experience that is unmistakably Hublot. Arriving brand new, this reference represents the pinnacle of the line in terms of material prestige and visual drama.

The Big Bang was introduced by Hublot in 2005 as the definitive statement of the brand's "Art of Fusion" philosophy—the deliberate marriage of unexpected materials, from precious metals to rubber, carbon to ceramic. The Unico designation elevates the concept further, signifying that the watch is powered by an in-house developed movement rather than a sourced caliber. This commitment to manufacture-level movement production represents a significant milestone in Hublot's evolution and adds considerable horological credibility to the collection's already bold identity.

At 45mm, the Big Bang Unico 411.MX.1138.RX commands the wrist with authority. The yellow gold case brings warmth and luxury to the composition, while the matching yellow gold bezel—fitted with Hublot's signature H-shaped screws—frames the dial in a way that is both architecturally precise and unmistakably sporty. The skeleton dial reveals the automatic chronograph movement beneath, with its bridges, wheels, and column wheel visible through the open workings, rewarding close inspection with exceptional mechanical detail.

Versatility is built into the purchase: the 411.MX.1138.RX ships complete with both a black rubber strap and a titanium bracelet. The rubber strap underscores Hublot's founding DNA—the brand was among the first luxury watchmakers to pair a gold case with a rubber strap—while the titanium bracelet offers a more formal, integrated look. Swapping between the two is straightforward thanks to Hublot's one-click strap-change system, making this single reference capable of covering a wide range of occasions.

For collectors seeking a statement timepiece that bridges haute horlogerie openworking with bold sports-luxury design, the 411.MX.1138.RX is a benchmark reference. Yellow gold Big Bang Unicos with skeleton Arabic dials occupy a particularly desirable position in the secondary market because they combine precious-metal prestige with the Unico's in-house movement credibility. Buying brand new from an authorized and trusted source ensures you receive the watch in pristine, untouched condition with full manufacturer warranty protection.

Bizak & Co. is proud to offer the Hublot Big Bang Unico 411.MX.1138.RX at a competitive price with the transparency and expertise you expect from a premier luxury watch dealer. Whether you are adding a flagship chronograph to an established collection or acquiring your first serious horological statement piece, our team is ready to guide you through the process.
