Majority movement of mechanical watches in the market are made by brass as they are reliable and they are easy to be malleable. It is also with low cost. The silver rhodium and nickel are always electroplated on the surface, so the brass is not easy to be recognized. But recently, Omega cooperated with Rory McIlroy to launch a perfect fake Omega Seamaster made by titanium.
The weight of Omega copy with gray dial is only 55 grams, which is exactly the weight of 10 pieces of A4 papers. In addition to the titanium movement, the material of the case is also very innovative. It is aluminum titanium alloy which is usually used to manufacture the fan blade of the jet engine.
The most important reason that why the imitation watch with aluminum-titanium case is so light is that the manual-winding mechanical movement is made by the titanium. Like other models of Omega, this timepiece offers resistance to 15,000 gauss.
