Click on “read more” to get an update on Hublot´s Magic Gold, to learn how it is produced and to see the new Big Bang Unico Magic Gold
In 2011 Hublot unveiled its Magic Gold – still the only scratch-resistant gold – a noble material protected by patents, certified as 18 carats by the Central Office for Precious Metals Control, and developed by Hublot in Switzerland alongside the prestigious EPFL (Swiss Federal Institute of Technology). Magic Gold is the hardest in the world, it can only be successfully machined using diamond. Its hardness of almost 1000 Vickers eliminates the traditional weak point of gold and its alloys, which are very easily scratched. Standard” well-designed 18 carat gold is only rated at 400 Vickers, most hardened steels at around 600 Vickers. Hublot has equipped itself with the means to produce this material in-house from start to finish. The high-tech foundry at the Nyon Manufacture is home to the ceramic sintering and high-pressure metal casting processes. This material is a fusion of 24 carat gold and the latest high-tech materials expertise. Components made from this material are produced using a complex process: A boron carbide powder is pre-formed in moulds very similar in shape to that of the finished parts, in this case the watch’s bezel. The pre-formed powder is then hardened at a very high temperature, creating a rigid, porous structure. After this operation, 24-carat gold alloyed with 3% molten liquid gold is injected under very high pressure with inert gas at a high temperature, allowing the metal to fill the ceramic pores and creating a “fusion” of the two to produce Magic Gold.
The first watches made from Magic Gold were presented at Baselworld 2012 in a very limited Big Bang Ferrari edition which reflected the shared DNA of the two brands: Exclusivity, innovation and technology.
Hublot is now producing the Big Bang Unico with a bezel in Magic Gold. Its bezel is indeed one of the components most susceptible to scratches and unique, instantly recognisable through the typical colour.
The mastermind behind the Magic Gold ist Senad Hasanovic, the Hublot Materials Science Engineer. The picture show him in his laboratory at the Hublot manufactory in Nyon in Switzerland
