The Art of Fusion: Hublot's Unrivaled Expertise in Colored Ceramic

Hublot’s brand-defining mantra, “The Art of Fusion,” was established by the legendary Jean-Claude Biver upon the relaunch of the brand in the early 2000s. It began with the audacious pairing of a gold case with a rubber strap and has since evolved into a full-fledged materials science laboratory. While many brands experiment with ceramic, most are confined to black and white, as the sintering process—where ceramic powder is fused under immense heat and pressure—typically burns away metallic oxides used for color. Hublot, through its own R&D department in Nyon, Switzerland, developed and patented a method to create vibrant, color-stable ceramic without compromising its hardness or scratch-resistance. This proprietary process allows them to achieve brilliant hues that remain permanently vivid.

This technical dominance has been demonstrated time and again. The release of the Big Bang Unico Red Magic (Ref. 411.CF.8513.RX) in 2018 stunned the industry with its intensely saturated red ceramic, a color previously thought impossible to stabilize. Since then, Hublot has expanded its palette to include striking blues, deep greens, and a particularly memorable Spirit of Big Bang in bright orange ceramic. The new Summer editions, with their soft, matte-finished pastel tones, represent a different kind of mastery. Achieving a delicate, uniform pastel shade is arguably as complex as a saturated primary color, requiring an even more precise control of pigments and firing temperatures. It showcases a nuanced and sophisticated evolution of their craft, moving beyond sheer boldness to embrace a more subtle, yet equally complex, chromatic language.

A Closer Look: The Big Bang Unico Summer Ceramic Editions

The two new models are presented in the contemporary 42mm Big Bang case, a size that offers significant presence without the heft of the original 45mm models. The chosen material is a micro-blasted and polished ceramic, which yields a contemporary matte finish that absorbs light rather than reflecting it. This texture enhances the softness of the pastel colors, making the watches feel sophisticated and modern. The iconic "sandwich" construction of the Big Bang case is on full display, with its six H-shaped titanium screws securing the bezel, a signature design element that remains a pillar of the collection's identity.

The open-worked dial, another Hublot signature, puts the mechanical heart of the watch front and center. The star of the show is the column wheel of the UNICO chronograph, visible at the 6 o'clock position. The sub-dials are clean and legible: a 60-minute counter at 3 o'clock which also incorporates the date window, and the running seconds at 9 o'clock. The applied numerals and hands are generously filled with Super-LumiNova, ensuring readability in all conditions. Each watch comes with two straps, easily interchangeable thanks to Hublot’s patented One-Click system. The first is a color-matched structured rubber strap, and the second is a Velcro strap, reinforcing the casual, summer-ready vibe of the release.

The Engine: An In-House UNICO 2 Flyback Chronograph

Beneath the sapphire crystal lies the Calibre HUB1280, also known as the UNICO 2. This is the second generation of Hublot's flagship in-house chronograph movement, redesigned to be slimmer and more refined than its predecessor, allowing for its use in the more wearable 42mm cases. This is not merely a generic movement hidden behind a caseback; it is an integral part of the watch's design and appeal. Comprising 354 components, the UNICO 2 is an integrated flyback chronograph, a sophisticated complication that allows the user to reset and restart the timer with a single push of the bottom pusher, without needing to stop it first.

The architecture is thoroughly modern. It features a bi-directional automatic winding system, a robust 72-hour power reserve, and a silicon escapement for improved anti-magnetism and chronometric stability. For the true watch nerd, the most compelling feature is the visibility of the mechanism from the dial side. Unlike traditional chronographs where the column wheel is hidden on the back, Hublot proudly displays this critical component at 6 o'clock. Watching the crisp, mechanical action of the column wheel engaging the chronograph levers is a piece of horological theatre that few other brands offer. It’s a testament to Hublot's confidence in their engineering and a core part of the Big Bang's mechanical-industrial aesthetic.

Collector Context: The Big Bang "Reloaded" and The Debate Over "Fun"

These Summer editions do not exist in a vacuum. They arrive on the heels of the "Big Bang Reloaded" initiative, a central theme for Hublot at Watches & Wonders 2026. This "Reloaded" concept involves refining the iconic Big Bang design with subtle ergonomic improvements, updated materials, and a renewed focus on the technical prowess of the UNICO movement. The new 42mm case, the advanced ceramic technology, and the UNICO 2 calibre place these Summer editions squarely within this forward-looking strategy. They demonstrate how the foundational Big Bang DNA can be adapted for contemporary tastes while pushing technical boundaries.

Hublot has long been a polarizing brand among traditionalist collectors, often sparking the debate of "substance versus style." Some critics dismiss vibrant releases like these as mere fashion accessories. However, this view overlooks the serious engineering involved. To create these watches, Hublot must operate at the highest levels of industrial manufacturing and material science. The UNICO 2 is a genuinely impressive, modern chronograph calibre by any objective measure. Therefore, these pieces challenge the collector to look past the color and appreciate the underlying technical achievement. They pose the question: Can a watch be both technically serious and unabashedly fun? Under the leadership of CEO Ricardo Guadalupe, Hublot's answer is a resounding "yes."

Frequently Asked Questions

How hard is it to make colored ceramic watches?

It is exceptionally difficult. The process involves sintering ceramic powder at temperatures often exceeding 1,400°C. At this heat, most color pigments vaporize. Hublot's patented process involves manipulating pressure and heat to fuse the ceramic without burning the pigments, allowing them to create saturated, stable colors like bright red, blue, and these new pastels. This is a proprietary technology that gives Hublot a significant edge over competitors and is a true hallmark of their in-house manufacturing capabilities.

Is the Hublot UNICO a good movement?

Yes, the HUB1280 UNICO 2 is a highly regarded modern movement. It is designed, developed, and assembled entirely in-house by Hublot in Nyon.
