The Sang Bleu series, created in collaboration with Hublot and Maxim Pleshia-Buchi, is one of the most creative watches of the new millennium. The latest addition to the lineup is called the Hublot Spirit of Big Bang Sang Bleu Sapphire, and it fully justifies that name. The Spirit of Big Bang Sang Bleu is based on the Plescia-Buchi corporate identity, based on the use of geometric shapes, multiple lines and inclined surfaces.
The Hublot Spirit Of Big Bang Sang Bleu Sapphire watch on your wrist is an absolute blast and a source of endless charm. A watch with a sapphire case is a special kind of coolness. But these watches are on a par with the most complex models in terms of design and execution. Hublot claims that it takes 100 hours of work to make the Sang Bleu Sapphire case, which shows how advanced manufacturing technology has been since the first sapphire case watches appeared, claiming 1,000-hour production times per unit.

The end result is simply incredible. For some reason, Sang Bleu watches continue to occupy a place among those rare watches in which there are practically no compromises in design. Instead, it seems that the finished product was exactly as it was originally intended. Sapphire is extremely fragile, and there are only a limited number of ways it can be cut and drilled before it cracks.
A large number of faces and angles amaze the imagination. The vast majority of watchmakers — even the few who already have experience working with sapphire case watches — would reject such a design if it were offered to them. This achievement belongs to Hublot.

The Hublot Spirit Of Big Bang Sang Bleu Sapphire is 42 mm wide, 15.7 mm thick and water resistant to 100 meters. The bezel, the middle part of the case and the back cover are made of polished sapphire crystal, which is practically scratch—resistant – unless you use a diamond. The buttons, crown, H-shaped screws, and folding clasp are carved from titanium. Overall, the Sang Bleu Sapphire watch feels moderately light, soft and very special on the wrist, even when combined with a rather stiff and not quite beautiful translucent rubber strap. The “One-Click” strap quick release buttons from Hublot have been integrated into the case.
The dial has a wide ring on which there is a clock and a date window, on the sides of which there is a transparent disk with a minute scale. The arrows are made in Sang Bleu’s signature style, with solid glowing areas marking parts of the arrow pointers. The chronograph’s hand has a counterweight of equal length, which adds an organized madness to the dial, as do the hands of the additional dial. The rest of the dial is missing, revealing parts of the mechanism. All this is covered with faceted sapphire crystal on the front.

The Hublot Spirit of Big Bang Sang Bleu Sapphire is equipped with the HUB4700 Caliber, which is a modified El Primero from Zenith, a subsidiary brand of Hublot as part of LVMH. The Hublot 4700 calibre operates at the proprietary El Primero frequency of 5 Hz and has a 50-hour power reserve, replenished by a massive and largely symmetrical rotor. The Hublot Spirit of Big Bang Sang Bleu Sapphire watch costs $143,000.
