====== Rubber ====== {{wst>image_cl|Hublot|Big Bang King Porto Cervo|Big Bang King Porto Cervo by [[Hublot]] with white rubber|210px}} Material === The material caoutchouc === The word origin of caoutchouc comes from the American Indian (//cao// = tree and //ochu// = tear), which means "Tears of the tree." The material was thus produced from tree or plant juices. In the 18th Century the knowledge about the collection of this material (rubber) came from Central America to Europe. Rubber comes in a natural (natural rubber) and in an artificial (synthetic rubber) form. Taking the total rubber demand the second variant delivers about 60%. === Rubber in the field of watches === Lately rubber is used more and more as a basic material for watch bracelets. In the field of luxury the introduction of natural black bracelets made from rubber by the Italian [[Carlo Crocco]] stired much attention in the [[1980]] years, who equipped the "Hublot" (porthole) models of his brand [[Hublot|MDM]] with this, and hereby created an innovative link between [[gold]] and synthetic. [[Jean-Claude Biver]], who came to [[Hublot]] in [[2004]], has developed this approach further with his "fusion" concept and in the success model [[Hublot Big Bang|Big Bang]] has united a whole series of natural and synthetic materials together. {{tag>Terms Watch_materials}}
