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.
