Hublot Big Bang Reloaded


News

An icon of audacity and mastery, from caliber to material
La Cote des Montres - April 21st, 2026

 
 


 
Born from gold and rubber in 1980, Hublot shook the industry with the Big Bang in 2005 and claimed mechanical independence in 2010 with the Unico, its first in-house chronograph. Since then, mastery has been its statement. From caliber to material to design, Hublot challenges conventions from the inside out. Building on the Big Bang’s 20th anniversary, Hublot presents the Big Bang Reloaded, an evolution of the openworked Big Bang Unico. The 44 mm collection is crafted from the materials that built Hublot, several of which celebrate key anniversaries in 2026. In this reloaded vision, the Unico caliber takes center stage: color, contrast and architecture amplify the chronograph’s unique construction, with the dial-side column wheel and integrated flyback architecture designed to be more visible than ever.

 
“The Big Bang Reloaded is a masterful statement. It embodies Hublot’s growth as a Manufacture and the evolution of the Big Bang collection and the Unico caliber over time. Hublot introduced the Big Bang Original featuring the Unico caliber earlier this year, inspired by the 2005 original model with a closed dial, yet reimagined and powered from now on by the Unico manufacture caliber. That was a turning point: our in-house caliber now drives the entire Big Bang collection. The next step for us was clear: to re-engineer the openworked Big Bang Unico itself, now more expressive and rebuilt from the inside out”, said Julien Tornare, Hublot CEO.

 

From the inside out
 

 
 

In 2026, the icon returns, rebuilt from the inside out, carrying the same DNA with new energy, evolved mechanics, sharper design and a stronger identity. The Big Bang Reloaded ushers the Big Bang and the Unico legacy into the next era.

 

Inside
 

The UNICO  
 

Launched in 2010, just a year after the debut of Hublot’s Manufacture, the Unico caliber has continuously evolved, with reworked components, optimized architecture and refined proportions. In 2018, the base caliber and chronograph module became a fully integrated caliber, re-engineered for higher performance and trimmed to fit into multiple cases. Sixteen years after its launch, that evolution continues, with a caliber that is even more visible, taking center stage.

 
The Big Bang Reloaded brings performance and legibility to the forefront. As one of the most advanced integrated chronographs of its generation, the Unico caliber features 5 patented innovations: backlash-compensating oscillating clutch, an anti-shaking chronograph hand system, a “zero friction” ratchet wheel blocker, a watch rate fine-adjustment system and highly shock-resistant time-setting. Beyond amplifying the visibility of the caliber’s architecture and technical depth, this reloaded vision places the Unico caliber at center stage, with color and contrast making its mechanics more visible than ever. The color-highlighted column wheel at 6 o’clock and the dual oscillating clutch at 8 o’clock immediately draw attention to the manufacture flyback chronograph caliber. The chronograph counter at 3 o’clock has been redesigned, the date repositioned between 4 and 5 o’clock and the flyback function reinforced with subtle color details. A new chronograph hand marks precision in action. On the back, contrast plays across a new openworked rotor featuring a cut-out H engraved with the inscription “Hublot. Design. Manufacture. Nyon”, along with the balance, barrel and going train.

Amplified Big Bang Architecture  
 

The Big Bang Reloaded stays true to its iconic design while asserting a bolder, sportier character. The 44 mm case features amplified architecture with a two-part bezel, creating sharper contrasts and enabling dynamic interaction between materials and finishes. The multilayer dial plays with textures and surfaces, giving depth and a technical edge. The chronograph becomes a standout feature, with a colored ring on the 4 o’clock push-piece, a redesigned minutes counter at 3 o’clock, a flyback inscription and the date repositioned between 4 and 5 o’clock. Each watch comes with two wristbands: one in fabric-inspired rubber with H-pattern stitching and the other in classic black rubber, both secured by a folding clasp and patented One Click system enabling either an instantly sporty or elegant style.

 

Material statement
 

 
 

The Big Bang Reloaded celebrates Hublot’s mastery of materials and key anniversaries: 20 years of the All Black Concept (2006) and 15 years of Magic Gold (2011). These permanent collection timepieces fuse decades of research, innovation and craftsmanship into a single icon. The Magic Gold model celebrates the world’s first scratch-resistant 18K gold, the second hardest material after diamond, created through four years of R&D in partnership with EPFL’s Metallurgy Lab, produced entirely in-house at Hublot Manufacture in Nyon and distinguished by its signature bronze glow. Ceramic takes shape in three references: the All Black edition marking 20 years of the radical “visibility through invisibility” concept; along with blue and dark green models showcasing Hublot’s full-color high-tech ceramic mastery rendering this material 300 Vickers harder than its conventional counterpart. The fifth reference blends Titanium and Black Ceramic, combining lightweight aerospace-grade titanium with technical ceramic to ensure robustness, along with a titanium bezel and case fitted with a black ceramic case-back, just like the first Big Bang Unico launched in 2013.

About Hublot
 

 
 

In 1980 and for the first time, a watch dared to put a gold case on a rubber strap, turning the luxury watch world upside down in the process. Named for the porthole-shaped bezel with its exposed screws, Hublot was born and with it, the Art of Fusion.

 
In 2005 the brand took this exercise in creative thinking to a new level with the Big Bang and its iconic design, size and layered construction case. That same year, Hublot received the Best Design award at the Grand Prix d’Horlogerie de Genève. Since then, spurred by this revolutionary mindset, the Big Bang has never stopped reinventing itself. The twenty-first century has its first watch Icon.

 
The concept of fusion is omnipresent, the guiding principle for every collection. Big Bang timepieces reshape the geometries of time; Classic Fusion balances boldness and restraint, while the Exceptional Timepieces overwrite expectations to create unprecedented horological objects. With its disruptive approach of challenging convention, Hublot’s DNA is transcribed in the Unico, Meca-10 and tourbillon in-house calibers, to add another tier of meaning to the Art of Fusion.

 
Since 2026, Hublot’s commitment to technical excellence has been backed by an evolved warranty structure for eligible timepieces purchased from January 1, 2026 onwards, featuring a 5-year basic warranty and the possibility of an additional 5-year extension for eligible timepieces through the Hublotista program, provided the basic warranty is still active at the time of registration. This would extend the coverage up to ten years.

 
Alchemy is ingrained into Hublot and not just at La Manufacture. Magic can take place on a football pitch, producing partnerships with major events (UEFA Champions League and UEFA Euro™). Sometimes it happens at a concert, a basketball match, an artistic performance or at a unique gastronomic experience with Hublot’s family of starred Chefs. And so, the Hublot Vibes come to life, through shared moments of exaltation amongst the Hublotistas, its very own community of proud Hublot owners. The Art of Fusion goes beyond the tangible. It is a way of being, the Hublot way of life.

 

The uniqueness
 

of the Hublot UNICO in-house caliber  
 

Born in 2010, the Unico was the first caliber entirely designed, developed and manufactured in-house by Hublot, marking a new era of independence, innovation and identity for the brand. Over the years, it has evolved into a bold and unmistakable signature of Hublot watchmaking, known for its robust and revolutionary chronograph design.

 
With standout features like a front-facing column wheel, silicon escapement, the Unico caliber is a mechanical force that’s as visually striking as it is technically advanced. It’s not just what powers the watch, it’s what defines it.

 
Key features include an integrated flyback chronograph precise to 1/8th of a second for instant reset and restart, an accuracy of -2/+4 seconds per day, a 72-hour power reserve. The caliber also holds five patented innovations, covering: a backlash-compensating oscillating clutch, an anti-shaking chronograph hand system, a “zero friction” ratchet wheel blocker, a watch rate fine-adjustment system and highly shock-resistant time-setting. all rigorously tested through Hublot’s Chronofiable® protocol to ensure optimal performance, reliability, and precision.
