Hublot Big Bang Unico Winter Sapphire automatic skeleton dial rubber strap 42 mm

Big Bang Unico Winter Sapphire: winter in its purest form

With the Big Bang Unico Winter Sapphire, Hublot offers a radical and exclusive interpretation of the Big Bang universe, where the winter season becomes a true aesthetic language. This creation does not merely evoke winter through color; it captures its very essence through transparency, light, and the purity of sapphire.

Limited to just 30 pieces, this Big Bang Unico Winter Sapphire ranks among the rarest and most spectacular creations in the collection. It illustrates Hublot’s ability to push the technical and aesthetic boundaries of contemporary watchmaking.

Design & architecture: the Big Bang in total transparency

The Big Bang Unico Winter Sapphire 42 mm reprises the iconic architecture of the Big Bang Unico, recognizable by its layered construction and powerful volumes. Here, however, this architecture visually dissolves in favor of the total transparency of polished sapphire, used for both the case and the bezel.

This fully sapphire execution transforms the watch into a true object of light. The emblematic lines of the Big Bang remain present, yet appear to float around the movement, offering a novel interpretation of form and mechanics. The rhodium-plated skeletonized dial further enhances this sensation of lightness and depth, revealing every component of the chronograph.

Proportions & presence on the wrist

With a diameter of 42 mm, the Big Bang Unico Winter Sapphire retains balanced proportions, faithful to the standards of the collection. Despite the complexity of the sapphire case, the watch maintains a controlled presence on the wrist, enhanced by the transparency that visually lightens the overall design.

Its water resistance of 50 meters confirms that this is above all an exceptional timepiece, conceived as a horological work of art to be worn with care, rather than as a sports chronograph intended for the most demanding uses.

In-house Unico HUB1280 movement: the heart revealed

At the center of this Big Bang Unico Winter Sapphire beats the in-house HUB1280 Unico calibre, an automatic flyback chronograph developed and assembled by Hublot. Designed from the outset to be visible, this movement is expressed here without any visual barrier, fully showcased by the sapphire case.

Featuring a column wheel on the dial side and a dual clutch system, the Unico calibre guarantees precise and smooth chronograph operation. It offers a power reserve of approximately 72 hours and is built from 354 components, optimized to enhance reliability and robustness despite the complexity of the overall construction.

Sapphire: craftsmanship and technical mastery

Creating a case entirely in polished sapphire crystal represents one of Hublot’s major technical achievements. This synthetic material, extremely hard and complex to machine, requires hundreds of hours of research, shaping, and polishing.

By mastering sapphire, Hublot does not merely seek a spectacular effect: transparency becomes a design tool, revealing the movement, volumes, and construction of the watch. Each Big Bang Unico Winter Sapphire thus becomes a work of horological art, where mechanics and case merge into a single entity.

Strap & exclusivity

The watch is delivered on a white rubber and blue calfskin strap, reinforcing the model’s winter identity. An additional white rubber and white calfskin strap is also provided, allowing the style to be adapted according to personal preference.

This Big Bang Unico Winter Sapphire benefits from online and boutique exclusivity and includes comprehensive Hublot servicing, ensuring the long-term precision and performance of the timepiece.

Limited edition of 30 pieces

Produced in only 30 pieces worldwide, the Big Bang Unico Winter Sapphire is aimed at a select circle of collectors and enthusiasts of contemporary high watchmaking. This extreme rarity further enhances the exceptional character of the piece, well beyond its aesthetic treatment.
