"Sapphire Crystal" with its unique personality

Hublot is a brand that actively uses cutting-edge materials, including sapphire crystal. Let's start by looking at how Hublot uses these materials.

Achieving both transparency and hardness

Hublot's sapphire crystal allows the internal structure of the watch to be seen while also providing a high level of durability to protect the movement. To enhance the artistic quality of watches made with this material, Hublot now offers a variety of colored sapphires, including blue, yellow, green, and orange.

The sapphire crystal that Hublot uses in its watches is an extremely hard mineral, said to be second only to diamond, the hardest material in the world.

Hublot has used sapphire crystal, which is extremely difficult to process due to its hardness, not only for the crystal but also for the case and bezel, giving the entire watch an overwhelming sense of transparency.

Hublot's sapphire watches combine excellent durability and scratch resistance with unparalleled transparency thanks to their all-round skeletonization.

A bracelet that matches the case

Big Bang Integral Tourbillon Full Sapphire

The Big Bang Integral Tourbillon Full Sapphire was released in 2021. Not only is it the first time that sapphire is used on the bracelet, but like the Big Bang Integral on which it is based, it also incorporates a design that creates a sense of unity between the case and bracelet.

The Big Bang, released by Hublot in 2021, also features sapphire crystal on the bracelet, making it the industry's first all-sapphire model.

The structure of the Big Bang was revised to incorporate the sapphire crystal bracelet, and it appears that considerable effort went into developing it.

The base for the Full Sapphire model is the Big Bang Integral, which features an integrated case and bracelet. While improvements have been made in many areas, the stunning harmony between the case and bracelet is also utilized in the Full Sapphire model.


The allure of Hublot and sapphire crystal

What is the appeal of Hublot's sapphire watches? The key points are the movement, which has a well-balanced layout, and the texture of the sapphire crystal, which changes its appearance depending on the color.

Visualized internal mechanisms

Hublot is a manufacture brand that produces watches in-house, from the movements onwards, and has developed a variety of high-performance mechanisms, including the Unico and Meca-10.

Hublot movements are characterized by their innovative and complex design, which is designed to be seen as a showpiece, with attention paid to not only functionality but also the layout of the parts.

Hublot's Sapphire watch allows visitors to see the internal mechanism, allowing them to appreciate the design and intricate movement of the movement, which represents the brand's advanced technical expertise, from all angles.

Beautiful colored sapphires

One of the great attractions of Hublot's sapphire watches is that they continue to produce vibrant colored sapphires using their unique coloring technology.

Until now, the production of colored sapphires had been avoided due to the extreme difficulty of achieving a uniform color and the tendency for them to break during the manufacturing process, but Hublot shocked the industry in 2017 by releasing a blue and red colored sapphire model.

Since then, Hublot has continued to use colored sapphires in cases, including black, yellow, green, and orange.
