Luxury watch brand Hublot has unveiled its new "Big Bang Sapphire Sky Blue" model, which utilizes its unique sapphire crystal processing technology. This model will be released in a limited edition of 100 pieces worldwide and features a design that evokes the boundless sense of freedom of a summer sky. At its heart is the "MECA-10" movement, which achieves a long power reserve of approximately 240 hours. This new model embodies Hublot's advanced technical capabilities in innovative materials and exceptional design.

The transparent beauty created by innovative sapphire crystal.

 Hublot has consistently pushed the boundaries of watchmaking by using sapphire crystal, a material notoriously difficult to process due to its extremely high hardness. In the newly announced model, a polished sapphire crystal case and bezel are combined with a movement colored in a vibrant sky blue, creating a sense of boundless freedom reminiscent of a summer sky. The case and bezel are secured with the brand's iconic H-shaped titanium screws, and a highlight is the transparent, see-through structure from the dial to the case back.

The refreshing contrast between the transparent sapphire crystal and the vividly colored sky-blue movement is striking. The see-through dial allows you to appreciate the intricate design of the Cal.HUB1201, a mechanical, in-house developed hand-wound movement with a sense of depth.

 Furthermore, it features a sky-blue structured rubber strap with lines that create a sense of depth. The case and dial, which reveal the heart of the intricate mechanism, are made of sapphire crystal, and the ability to admire the movement through the see-through dial is a particularly attractive feature.

The history of "Art of Fusion" and a long-term warranty of up to 10 years.

 Founded in 1980, Hublot brought a new dimension to the luxury watch industry with its innovative idea of ​​combining gold cases with rubber. The concept of "Art of Fusion," which fuses different materials, remains a guiding principle for all of its collections today. Hublot's "Big Bang," created in 2005, was highly acclaimed for its fusion of different materials and its multi-layered case, and is now widely known as a central collection that drives the brand.

 As a testament to its unwavering commitment to reliability and technical excellence in its products, Hublot has established a comprehensive after-sales service system. This model comes with a five-year basic warranty, and by registering as a "Hublotista," an additional five-year extended warranty is available. This means that customers can receive generous warranty service for a total of up to 10 years, which is a major attraction of Hublot.
