Hublot Big Bang Unico Water Blue Sapphire

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.
