With the Big Bang Sapphire Sky Blue, Hublot delivers a new demonstration of its expertise in mastering sapphire crystal. More than a mere chromatic variation, this edition limited to 100 pieces illustrates the Swiss manufacture’s ability to push back the frontiers of watchmaking creation. Spectacular transparency, an exceptional in-house movement and skeletonised architecture come together in a watch that seems suspended between sky and light.
For several years now, Hublot has established itself as one of the most daring manufactures in the industry. While the House is often associated with the Art of Fusion, it has also become an essential reference in the development of sapphire crystal, a material as fascinating as it is demanding to work with.

Sapphire, a specialty turned signature

Sapphire crystal is mainly known for protecting the dials of high-end watches. But Hublot chose to do far more with it. After years of research and development, the manufacture managed to machine cases made entirely from this material, renowned for its exceptional hardness, sitting just behind diamond on the Mohs scale.
This technical feat is no longer limited to transparent sapphire. Over the collections, Hublot has developed different tints, giving rise to coloured creations that retain all the optical purity of the material. With this new Sapphire Sky Blue, the brand evokes a clear summer sky through a particularly luminous sky-blue hue that seems to dissolve the boundaries between the watch and its surroundings.
The fully polished 44 mm case is made of sapphire, as are the bezel and the transparent case-back. The famous H-shaped titanium screws immediately recall the Big Bang’s visual identity, while the sky-blue rubber strap harmoniously extends this sense of lightness.
The Meca-10 calibre, a spectacular mechanism

Beyond its aesthetics, this Big Bang Sapphire Sky Blue seduces above all through what it reveals. Its transparent architecture puts the in-house HUB1201 Meca-10 calibre on display, one of the most emblematic movements developed by Hublot.
First unveiled in 2016, the Meca-10 profoundly renewed the codes of the skeleton watch. Where most movements seek to hide their construction, this one does exactly the opposite: it exposes its mechanics like a genuine work of engineering.
Inspired by Meccano-style mechanical construction, its architecture showcases each of the 223 components that make up the movement. The openworked bridges offer a complete view of the mechanical organs, while the two barrels mounted in parallel provide an impressive ten-day power reserve, or 240 hours.
Another feature particularly appreciated by enthusiasts: the power-reserve display relies on an ingenious rack-and-pinion system. Two racks travel gradually across the movement to indicate the remaining energy with great precision, a technical solution that has become one of the Meca-10’s signatures.
A watch that plays with light

One of the great strengths of this Sapphire Sky Blue edition lies in its constant interaction with light. Depending on the viewing angle, the case almost completely disappears, leaving the movement seemingly floating in a striking play of transparency.
The matte sky-blue skeletonised dial and the matching bridges reinforce this impression of depth. Each component seems suspended in the void, offering a mechanical spectacle that shifts with the slightest movement of the wrist.
This aesthetic pursuit is never gratuitous. It perfectly accompanies Hublot’s philosophy, which consists in bringing innovative materials, contemporary design and high technical mastery into dialogue.
An exclusivity aimed at collectors

Produced in just 100 pieces worldwide, the Big Bang Sapphire Sky Blue naturally addresses collectors drawn to the manufacture’s most exclusive creations.
Priced at 82,700 euros, it also benefits from the “5+5” international warranty offered by Hublot. This programme, among the most generous in the watchmaking industry, can extend coverage to ten years, illustrating the brand’s confidence in the quality of its creations.
With this new Big Bang Sapphire Sky Blue, Hublot is not merely seeking to offer a new colour. The manufacture continues its exploration of cutting-edge materials while demonstrating that a timepiece can be at once an object of engineering, a sculpture of light and a true showcase of its expertise. A spectacular creation that confirms, once again, that sapphire has become far more than a material at Hublot: it is now one of the most accomplished expressions of its watchmaking identity.
