Hublot teams up with renowned tattooist Maxime Plescia-Büchi fora collaboration series. With Plescia-Büchi’s assertive relief placed ontoHublot’s flagship Big Bang model, it becomes a welcomed alchemy. A magic circle trapped onto the dial if you will; attention is drawn towards these three-dimensional leylines etched onto the geometry of the watch.

Last year, Plescia-Büchi moved to the Spirit of Big Bang—where the Big Bang 42mm model is infused with a “barrel”-shaped case. In a reveal, the Spirit of Big Bang Sang Bleu is a skeletonised automatic chronograph(HUB4700) with the date at 4:30, a 50-hour power reserve and are designed oscillating weight. Limited and fashioned in three materials—titanium, ceramic, gold—the Spirit of Big Bang Sang Bleu took centrestage at the Salone del Mobile inMilan.

Once more into the breach, another Spirit of Big Bang Sang Bleu was released, this time in sapphire. The material’s transparency enhances the sharpness of Plescia-Büchi’s designs; with the only non-transparent elements being the crown, the pushbuttons, the screws on the case, the6 H-shaped screws on the bezel and the folding clasp. While it is as tough as a diamond (9 on the Mohs scale),the Spirit of Big Bang Sang Bleu in Sapphire is, unfortunately, impervious to being sold widely as it’s limited to only 100 pieces worldwide
