HUBLOT Big Bang Integral Tourbillon Full Sapphire Limited Edition

With the Big Bang Integral Tourbillon Full Sapphire, Hublot has taken its Art of Fusion to its ultimate conclusion. A new integral bracelet and case custom-made from sapphire: this feat affirms yet again the technical proficiency and the exceptional expertise that Hublot has acquired in the working of sapphire.

The Big Bang Integral Tourbillon Full Sapphire is the fruit of a long tradition. It is rooted in 2016, and the Big Bang Unico Sapphire, the first sapphire watch. With this piece, Hublot translated the expertise it had developed in machining very hard materials to create an exceptional series of sapphire watches. Today, Hublot is pushing these boundaries even further: the first Big Bang with an integrated case and bracelet, both of which are made from sapphire.

The case of this new Big Bang Integral Tourbillon Full Sapphire has been reconstructed in its entirety to house the Automatic Tourbillon movement. The goal: to remove almost all of the visible screws, overhaul the general geometry of the case to integrate it with the sapphire bracelet, develop a new case profile to house the sapphire bracelet, and rework the bridges and main plates to give them the illusion of being suspended in space.

Hublot also developed inserts and attachments which were reduced to their simplest expression, to allow light through every component. The case is thus composed of no fewer than 37 components, five of which are made solely from sapphire.

Extremely complex, the bracelet alone comprises 165 components, 22 of which are made from sapphire. Each component had its own industrial process. A third of these were specially designed to provide unique harmony with the transparency of the case, and to offer fluidity and flexibility. Of particular note are the titanium inserts Hublot developed, ultra-reduced to ensure they do not protrude either side of each bracelet link – a first for the manufacture, and probably for watchmaking.

In terms of the movement, the HUB6035 automatic manufacture calibre, entirely designed and manufactured in-house, is the beating heart of the piece. It demonstrates a perfect balance between the micro-rotor at 12 o’clock and the tourbillon at 6 o’clock, and also with its three transparent sapphire bridges, exclusive to this new Big Bang.
