Hublot Big Bang Yellow Gold 42mm

Detailed Features & Specifications — HUB4700

Calibre HUB4700 is the successor to the famous El Primero calibre – the first chronograph with integrated automatic winding (1969), which was at the same time the first mechanical chronograph with a frequency of 5 Hz (36,000 vibrations per hour), making a precision of 1/10 of a second possible. In a perfect fusion of tradition and innovation, this fully skeletonised movement is today fitted with a silicon regulating organ that ensures avant-garde performance, precision and reliability.

INNOVATIVE MATERIALS

From the first use of rubber in watchmaking, through the development of new precious alloys such as scratch-resistant Magic Gold, to the production of revolutionary composite materials such as ceramic and sapphire in unique colors – materials have always been at the centre of the Hublot universe. To realise its “Art of Fusion”, the manufacture has its own metallurgy and materials laboratory, working closely with the research and development department, as well as its own foundry. These innovative materials are developed and produced using the most advanced technologies, unique within watchmaking – technologies that come exclusively from Hublot.
