DESCRIPTION

  • THE PUREST BLUE: HUBLOT UNVEILS THE BIG BANG UNICO IN WATER BLUE SAPPHIRE

    April 1st, Geneva, Switzerland - As the king of advanced and experimental materials, Hublot once again demonstrates its unrivalled mastery of sapphire crystal and the many colours it can take on with the Big Bang Unico Water Blue Sapphire, a limited edition of 50 pieces.

    It was less than a decade ago that Hublot first experimented with the idea of having a watch case crafted in transparent sapphire. Never content with simply maintaining the status quo, Hublot went on to develop a wide palette of coloured sapphire. A laborious process, creating new colours of transparent sapphire requires far more than simply switching pigments. Each colour requires finding the precise formula and adjusting the process accordingly, to ensure a qualitative result both aesthetically and functionally. The challenge is further compounded by the complexity of the Big Bang’s unique layered construction.

    Water Blue sapphire marks the latest development from Hublot’s RCD department and its mission to keep finding new creative avenues by making the impossible a tangible reality. A light yet intense hue, Water Blue sapphire evokes tropical, crystal-clear waters, taking the wearer on a sensory voyage. Measuring 44mm wide, the case and bezel are matched by the translucent blue rubber strap, as well as the blue accents on open dial’s indexes and hands.

    The Big Bang Unico Water Blue Sapphire is powered by Hublot’s first in-house developed and manufactured calibre, the Unico. Built with a contemporary architecture, the automatic integrated chronograph movement with a column-wheel clutching system is composed of 354 components, simplified to ensure reliability and robustness. Its bi-directional winding system efficiently helps reach the Unico’s power reserve of 72 hours. For the Big Bang Unico Water Blue Sapphire, the movement is finished in a sleek grey tone to enhance the visual brightness.

    The Big Bang Unico Water Blue Sapphire is a limited edition of 50 pieces, available at Hublot boutiques and authorized retailers.

    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 (FIFA World CupTM 2010, 2014, 2018, 2022, Premier League, 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.

    BIG BANG 20TH ANNIVERSARY – A CELEBRATION OF THE BIG BANG REVOLUTIONARY MINDSET

    In 2005 the Big Bang marked the advent of a new era in watchmaking, more closely attuned than ever to the privileges of its name. Few timepieces have transformed contemporary watchmaking like the Big Bang. Twenty years after its launch, it remains the incarnation of a Manufacture that constantly pushes the boundaries of the unknown. Through exclusive materials and in-house movements, led by the Unico and the Meca-10, the Big Bang breaks with tradition —a notion it has never completely embraced. Singular for its bold aesthetic, plural for its versatility, this is the Big Bang.
