With that said, it wears extremely comfortably. 1 reason for this is that it is designed to not slip around on your wrist. The particular case and clasp design produce a “sandwich” effect where pressure to hold the eye in place comes in the top and bottom of your wrist even if there is excessive space on the side. Thus, despite the large size of the circumstance it’s designed such that it’s supposed to match well on even medium-to-smaller wrists (like my own). The Hublot Big Bang UNICO also seems effortlessly cool. OK, if cool for you is classic and reserved then it isn’t cool. The highly architected yet symmetrical lines together with the tapering design are equally modern but additionally proportionate. Why is the Hublot Big Bang UNICO cases a bit distinct are the large round chronograph pushers as well as this specific style of this hour markers and hands (that do, of course, vary somewhat from dial to dial).

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 44mm Price 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.
