2016: In a tour de force, Hublot cut a sapphire case on an unprecedented scale, mastering a complex material, which is both ultra-resistant and totally “invisible” thanks to its transparency.

2017: While coloured synthetic sapphires have been in existence since 1902, when they were invented by the French chemist Auguste Victor Louis Verneuil, melting sapphire is a complex and unpredictable process. Because its crystallisation process is unstable, it is difficult to obtain similarly coloured sapphires, even if they are produced simultaneously. Furthermore, bubbles and cracks can appear in the material, making the end result unsuitable for producing Big Bang cases. But the main challenge is in the size. Thus far, no coloured sapphires exceeding 2 kg have been produced. However, Hublot Big Bang Alligator Strap has now gone beyond this threshold. By pushing the limits of engineering and chemistry, it has developed a sophisticated and costly process that has resulted in the successful production of a large, transparent sapphire of perfectly uniform colour. Hublot heats aluminium oxide (Al2O3) — the raw material for sapphire — with a transition metal, chromium (Cr), at a temperature of between 2000 and 2050 degrees Celsius. The result is a coloured sapphire that retains all the original properties of a material which is ultra-scratch resistant, completely transparent and among the hardest in existence. The innovation extends to the colour — the first blue sapphire in the history of watchmaking.

This specific reference 411. CI.1190. LR.ABO14 model comes from a black ceramic situation that’s given at least 2 finishes from glistening to matte. It’s paired with black screws and other instance construction elements. This specific sort of all-black look means a lot to me, but it had been Hublot Big Bang Fake Vs Real that really helped popularize the all-black watch appearance that began to be a thing about 10 years ago. I was never a fan of most completely all-black watches but appreciated how a range of muted black colours made complex cases appear very intriguing. That combined with a legible dial is straight up my alley.So, it makes me glad that this particular orange and black Hublot Big Bang UNICO uses a sort of matte orange sherbet color for the outline of the hands and hour mark, making everything nice and legible. There is still SuperLumiNova luminant (the black paint at the hands and numerals), of course, which means you have some darkness viewing. With that said, black-colored luminant (although it glows green) is not likely to be as strong as lighter color lume paints – probably because the dark shade prevents some light absorption when charging the luminant.Hublot’s doctrine about “fusion” rings true since the Hublot Big Bang UNICO case is produced from a selection of materials. Not all of them are luxury materials, but honestly, some of those high-grade polymer resins used for your center case are extremely high functionality, adding both lightness and durability. I feel these substances also help make the case more shock-resistant. I also want to mention the situation screws which are not “aligned” as per the desires of a few of the more outspoken critics of the brand.

Case middle, bezel and case back cut from blocks of blue coloured sapphire. Flange, indices, Arabic numerals and hour/minute hands toned to match the colour of the sapphire, through contrast revealing the mechanism of the Unico HUB124 proprietary movement and its column wheel on the dial side. Hublot has also designed a series of 250 pieces in red sapphire by melting iron (Fe) with aluminium oxide.
