Hublot Presents The Big Bang Unico “Magic Gold” Watch

By Osheen Arakelian

Hublot, who developed a new method of producing a stunning 18-carat scratch resistant gold metal, made Magic Gold famous three years ago. Certified as 18 carats by the Central Office for Precious Metals Control, it is considered the only scratch resistant gold in the world of horology and also the hardest. It can only be successfully machined using diamond and its hardness of almost 1,000 Vickers eliminates the traditional weak point of the gold and its alloys (the standard being only 400 Vickers). It took several months of fine-tuning in the manufacture to machine the alloy into what’s presented in this timepiece and the quality most definitely shows.


This revolutionary material is fused with 24-carat gold and the latest high-tech materials expertise. Components are 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 watch’s bezel. The pre-formed powder is then hardened at a very high temperature, creating a rigid, porous structure. After this step, the 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 what we know as Magic Gold.


The timepiece chosen for this amazing metal to be utilised is the Big Bang Unico (which is a great choice in my opinion) and by using black micro-blasted ceramic for the case finish, helps the gold stand out much more giving it a real presence. The 45mm case size comes equipped with all the essential features you would expect to see from a Unico timepiece including a chronograph and date window at 3 o’clock. The movement tucked underneath is the HUB 1242 Unico automatic movement featuring the flyback chronograph with column wheel and double clutch visible on the dial through a skeleton dial. The movement is finished in black PVD and is developed and manufactured entirely in-house by Hublot and has approximately 72-hour power reserve.


A beautiful new timepiece with a great new revolutionary gold bezel that’s sure to be a hit with watch enthusiasts everywhere. For more info, please visit
