Carbon is the second most abundant element by mass (about 18.5%) after oxygen. This abundance, together with the unique diversity of organic compounds and their unusual polymer-forming ability at the temperatures commonly encountered on Earth, make this element the chemical basis of all known life, human body and diamonds included. In Hublot watchmaking, we use carbon to get carbon fibers thanks to carbon atoms! It is transformed in braided fibers and surrounded by resin, to create watch cases or components. This thermally decomposing man-made process permits to obtain extremely strong and light material. The weight of carbon fiber is less than 2.6 g/cm3. It is widely used in aviation, military, space, aeronautic, medicine industries and other high technologies. Actually, carbon fibers give a really contemporary style to the watches.
