As the undisputed Master of Sapphire, Hublot once again pushes the boundaries of horology with the new Big Bang Sapphire Sky Blue. Crafted from sapphire with a captivating sky-blue transparency, this limited edition of 100 pieces brings together cutting-edge mechanics. Featuring the innovative manufacture Meca-10 caliber, this watch is a testament to Hublot’s mastery of groundbreaking materials and exceptional design, evoking the boundless feeling of a summer sky.

 
First introduced in 2016, the Meca-10 challenged traditional watchmaking codes with an architecture inspired by mechanical construction systems. Designed around the movement, it puts its mechanics on full display through an innovative, highly visual structure. At its heart beats the HUB1201 manufacture manual-winding movement, composed of 223 components and built with a fully skeletonized Meccano-inspired architecture that reveals every element of its mechanical operation. Delivering an impressive 10-day power reserve, it is powered by two parallel mainspring barrels and features an unconventional rack-and-pinion system with sliding racks moving along a 9 o’clock to 3 o’clock axis, creating a distinctive dual power reserve display that has shaped the identity of the collection.

 
Since 2016, Hublot has become the undisputed Master of Sapphire, continuously expanding the possibilities of this exceptionally hard and transparent material. From clear sapphire to colors, the Manufacture has turned what was once considered impossible into one of its signatures.

 
The Big Bang Sapphire Sky Blue, housed in a 44 mm fully polished sapphire crystal case and bezel secured by H-shaped titanium screws, is paired with a structured sky-blue rubber strap. Its sapphire case-back reveals the mechanics within, while the matte sky-blue skeleton dial and matching movement bridges reveal the movement’s construction.

 
From its sapphire construction to its manufacture (Meca-10) movement, the Big Bang Sapphire Sky Blue embodies a powerful expression of innovation, mastery and boldness that define Hublot. This confidence is reflected in Hublot’s 5+5 warranty program, one of the most extensive in the industry, leading coverage to up to ten years. It stands as a tangible expression of the brand’s trust in its products and in the teams who design, develop and assemble them.

The Big Bang Sapphire Sky Blue is limited to 100 pieces and available at selected Hublot points of sale and online at hublot.com.

 

About Hublot
 

 
 

In 1980 and for the first time, a watch dared to put a gold case on a rubber strap, turning the luxury watch world upside down in the process. Named for the porthole-shaped bezel with its exposed screws, Hublot was born and with it, the Art of Fusion.

In 2005 the brand took this exercise in creative thinking to a new level with the Big Bang and its iconic design, size and layered construction case. That same year, Hublot received the Best Design award at the Grand Prix d’Horlogerie de Genève. Since then, spurred by this revolutionary mindset, the Big Bang has never stopped reinventing itself. The twenty-first century has its first watch Icon.


The concept of fusion is omnipresent, the guiding principle for every collection. Big Bang timepieces reshape the geometries of time; Classic Fusion balances boldness and restraint, while the Exceptional Timepieces overwrite expectations to create unprecedented horological objects. With its disruptive approach of challenging convention, Hublot’s DNA is transcribed in the Unico, Meca-10 and tourbillon in-house calibers, to add another tier of meaning to the Art of Fusion.

Since 2026, Hublot’s commitment to technical excellence has been backed by an evolved warranty structure for eligible timepieces purchased from January 1, 2026 onwards, featuring a 5-year basic warranty and the possibility of an additional 5-year extension for eligible timepieces through the Hublotista program, provided the basic warranty is still active at the time of registration. This would extend the coverage up to ten years.

Alchemy is ingrained into Hublot and not just at La Manufacture. Magic can take place on a football pitch, producing partnerships with major events (UEFA Champions League and UEFA Euro™). Sometimes it happens at a concert, a basketball match, an artistic performance or at a unique gastronomic experience with Hublot’s family of starred Chefs. And so, the Hublot Vibes come to life, through shared moments of exaltation amongst the Hublotistas, its very own community of proud Hublot owners. The Art of Fusion goes beyond the tangible. It is a way of being, the Hublot way of life.
