Big Bang Unico Yellow Sapphire

Detailed features & specifications

UNICO 2

The Unico 2 caliber was designed to equip smaller chronographs and also open the world of Hublot to new enthusiasts. It retains the unique design of its former version with a double coupling system visible from the dial side as well as a 72-hour power reserve. But thanks to various technical optimizations. including the introduction of a new. flatter automatic winding system. it has been reduced by 1.3 mm in thickness.
 

SAPPHIRE

In search of the perfect fusion between movement and case. Hublot engineers and chemists have researched and developed a transparent material which reveals the heart of the watch. all while being robust enough to effectively protect the mechanism. That’s how the Manufacture has become the expert of synthetic sapphire. a material from which it derives its aesthetic qualities that are unique within watchmaking – transforming each watch into a work of art.
