DESCRIPTION

  • HUBLOT UNVEILS A NEW COLOR RANGE WITH THE BIG BANG & SPIRIT OF BIG BANG COAL BLUE

    Hublot unveils a new sophisticated and powerful color range as part of its Big Bang family, designed for pieces that are both elegant and distinctive. Four models uniquely dressed in light: coal blue. A new color for Hublot, radiating a mysterious and subtle minerality and developed specifically for these four new references. It offers a novel and unexpected alternative within the Big Bang family, which is known for its bright, vibrant shades.

    This exclusive, saturated blue with stormy and mineral undertones, reveals its natural reflections when struck by light at a certain angle. It is a rare tone, difficult to capture, that borrows its constituents from gray, black and blue. A delicate alchemy is at play here, with Hublot seeking to combine its mineral depth with its natural brilliance.

    A solid dial with geometric patterns adorns these two watches for the first time: the 43-mm Big Bang Original Unico and the 42-mm Spirit of Big Bang. They share a common feature: a dial inspired by the pattern of carbon fiber. It weaves a color chart with alternating satin-finished and polished squares, with a reworked 3D effect to give it more depth and a new geometry.

    The Big Bang Original Unico is powered by the Unico Manufacture chronograph flyback caliber, with a three- day power reserve. The Spirit of Big Bang itself is powered by the high-frequency HUB4700 movement oscillating at 5 Hz (36,000 vib/h). Both pieces proudly display their shared DNA: titanium case, rubber strap, One-Click interchangeable system and titanium deployant buckle, bezel featuring six distinctive H-shaped screws, characteristically non-aligned for functional reasons.

    The Big Bang Original Unico Coal Blue is at the heart of the new Big Bang Original Unico range, which combines the esthetic of the Big Bang Original with the contemporary features of the Big Bang Unico. It features the same distinctive characteristics, including the new 43-mm case, the iconic reworked carbon fiber-effect dial, the Unico Manufacture movement and a sculpted diamond-patterned structured rubber strap reminiscent of the very first Big Bang watches equipped with the One-Click system.

    The other two pieces reflect the mineral character of the Coal Blue through the use of carbon in its purest state: diamond. The bezels of the Big Bang (33 mm) and the Spirit of Big Bang (32 mm) are set with diamonds – 36 on the former and 44 on the latter. Each dial is nestled within a bezel whose diamonds accentuate its subtle variations. All diamonds are certified according to the dual RJC (Responsible Jewellery Council) and Kimberley Process certifications, which guarantee the highest ethical standards. These diamonds comply with the 4Cs that define excellence: 0.76 carat for the Big Bang One Click and 0.70 carat for the Spirit of Big Bang, Color F, G, Clarity VVS and Excellent Cut.

    The piece thus retains its sporty feel but is dressed in shades of steel tinged with blue, with touches of light and preciousness. Finely sunray finished, the dials display the complexity of the Coal Blue shade on their surface, revealing its subtle shades of blue and gray in an ever-changing palette.

    Steel complements the two previous titanium versions. This alternative harmony of tones creates a consistent, modern and sophisticated esthetic. The different shades of gray in the steel create a cameo effect that blends naturally with coal blue. The transition is smooth. The juxtaposition of colors adds depth and visual complexity to the composition.

    “We have chosen to exploit the complementarity of our iconic Big Bang and Spirit of Big Bang watches. We are unveiling not two but four creations with boldly distinctive personalities, ranging from timeless elegance to sporty dynamism. With Coal Blue as the common thread, each design offers a unique perspective on this bold new color,” concludes Julien Tornare, Hublot CEO.

    These new Coal Blue editions are available at selected Hublot points of sale and online at hublot.com.

    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 movements, to add another tier of meaning to the Art of Fusion.

    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 EuroTM). 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 MOVEMENT

    Born in 2010, the Unico was the first movement 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 movement 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 movement also holds five patented innovations, covering: dual oscillating clutches, an anti-trembling system, a “zero friction” ratchet wheel blocker, a fine balance wheel adjustment system and constant-pressure friction system for the minute counter all rigorously tested through Hublot’s Chronofiable® protocol to ensure optimal performance, reliability, and precision.
