Hublot Big Bang Unico Integrated Blue Ceramic 42mm 451.EX.5123.EX - BRAND NEW

The Hublot Big Bang Unico Integrated in reference 451.EX.5123.EX represents one of the most visually cohesive and technically ambitious expressions in Hublot's storied Big Bang lineup. Introduced as an evolution of the original Big Bang concept, the Integrated takes the signature bold case architecture and binds it to a purpose-built bracelet that appears to emerge organically from the lugs, creating a single sculptural object rather than a watch and strap assembled separately. The result is a wristwatch that is as much a design statement as it is a precision timepiece.

The 42mm case of the 451.EX.5123.EX is crafted entirely from high-tech ceramic, a material Hublot has refined over decades of production. Ceramic is prized in watchmaking for its exceptional hardness, which renders it highly resistant to the everyday scratches and scuffs that affect steel or titanium counterparts. It is also hypoallergenic and maintains a consistent, deep luster that does not fade with time. The blue ceramic used throughout this reference creates a rich, saturated hue that shifts subtly under different lighting conditions, lending the watch a sense of depth and dynamism.

The dial of the 451.EX.5123.EX is finished in a complementary blue tone and populated with index hour markers that catch the light cleanly, ensuring legibility without disrupting the watch's monochromatic visual harmony. The ceramic bezel reinforces the seamless aesthetic, framing the dial in the same material and color family as the case and integrated bracelet. Together these elements produce a watch that feels deliberately total in its design intent, with no element feeling like an afterthought.

Powering this reference is an automatic movement, consistent with the Unico designation that has become synonymous with Hublot's in-house manufacturing capabilities. The Unico platform was developed to demonstrate that Hublot could produce sophisticated calibers entirely within its own manufacture, and it has since underpinned some of the brand's most celebrated references. Buyers can trust that the movement inside this watch reflects that same standard of in-house craft and precision.

On the wrist, the Big Bang Unico Integrated at 42mm occupies a confident but wearable footprint. The integrated ceramic bracelet contributes to a secure, comfortable fit while amplifying the watch's architectural drama. It is equally suited to dressed-down weekend wear and more polished occasions, making it a genuinely versatile centerpiece for any serious collection. The blue all-ceramic execution in particular has attracted strong collector interest for its rarity and distinctive character.
