— The world’s only scratch-resistant gold replica watches for sale, housing the automatic flyback chronograph movement Unico.

In celebration of the 10th anniversary of the Big Bang, Hublot reveals the Big Bang Unico Full Magic Gold. It is the fusion of a revolutionary material – the Magic Gold, which is the world’s only scratch-resistant gold, certified as 18K and developed by Hublot – and the iconic design of the Big Bang, with its Manufacture Chrono movement, the UNICO.

Since November 2011, when Magic Gold was unveiled to the world, Hublot has equipped itself with the means to produce this material in-house from start to finish thanks to its high-tech foundry at the Nyon Manufacture, which is home to the ceramic sintering and highpressure metal casting processes.

Magic Gold 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 preformed in moulds very similar in shape to that of the finished parts, in this case the cheap Rolex replica watch‘s bezel. The pre-formed powder is then hardened at a very high temperature, creating a rigid, porous structure. After this operation, 24K 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.
