Ever since it was founded in 1980, Hublot has stood for edgy designs combined with unusual materials and this year they’ve upped the ante with the Big Bang Unico Sapphire, a cool looking watch made of one of the hardest materials known to man – sapphire crystal. It won’t be easy to produce but there is a precedent: the Richard Mille RM 56-02, which was launched in 2014, limited to just ten pieces and took a year to make at a cost of 2 million USD. This new sapphire Big Bang is much more reasonably priced however, at 57,900 USD. And it has a larger scale production, with an impressive 500 units slated to be made. Featuring a window, case middle, bezel and case back, all cut from blocks of sapphire crystal, which is scratch resistant and almost as hard as diamonds. The watch is complemented by a skeletonized dial made of transparent resin and a translucent silicone strap. In fact, the only parts that aren’t seethrough are the titanium screws, crown and deployant buckle. It’s clearly impressive.
