Hublot Big Bang Sapphire Tourbillon

Presented at Baselworld 2018 watch exhibition, the new Hublot Big Bang Sapphire Tourbillon watch is completely transparent, including the case, dial, strap and tourbillon movement. The crystalline connections disappear to reveal the skeleton mechanics of the tourbillon, for which the cage is held in place by a strip cut from sapphire.

Sapphire is the hardest and most durable material after diamond. For the first time, its skeleton movement and see-through connections are revealed through ‘invisibility’, where only a few metallic gears sketch out the contours.

All of the parts are clear: the sapphire middle, bezel and the back of the case reveal crystal mechanics that seem to float. The dial and its numbers, index and power reserve indicator are all opalescent and flown over by perforated hands.

This 99-edition manufacture tourbillon represents a breakthrough in the technical and aesthetic use of sapphire. In addition to its 45 mm case, cut from a block of sapphire, the tourbillon strip is designed in the same material, which is almost indestructible.
