Fake Richard Mille‘s new exclusive material Gray Cermet
·The lightness of titanium matches the hardness of diamonds
The structure of the self-winding movement makes titanium proud. Its features include, in particular, the GMT display, which can be easily adjusted by the button at 9 o’clock, the 24-hour flyback chronograph and the annual calendar. The added gray cermet is suitable for the pure aerodynamic lines of the iconic case, measuring 50 x 42.70 mm and having a total thickness of 16.15 mm.
The unique gray color of cermet is attributed to the combination of metal zirconium base and high-performance ceramic blades. Its implementation needs to correspond to the rigor required to create the material itself. It is a challenge to heat and press very different kinds of materials together at high temperatures without changing their respective qualities.
Facts have proved that it is more difficult to obtain a uniform whole, because in order to comply with the REACH standard, nickel and cobalt that are usually used in this hard material series are excluded, thereby ensuring the safety of the European chemical production and use industry.
After years of development, Richard Mille and the IMI Group, which specializes in microtechnology, have removed these bad adhesives and retained only suitable materials. The innovative program used for this solution combines classic hot stamping with a series of powerful current pulses to improve sintering kinetics. This technique is called “rapid sintering”. Cermet has a density of 4.1 g/cm3 (lower than titanium) and a hardness of 2360 Vickers (almost the same as diamond’s 2400 Vickers). It is a wise choice. It can be used for bezels that are very easy to scratch and maintain overall brightness. The physical properties of cermets are widely recognized, so they are often used in bulletproof, external aerospace fuselage components, and brakes for racing vehicles.
The combination of a carbon fiber TPT strap, a grade 5 titanium caseback and a gray cermet bezel can significantly reduce the weight of the RM 11-05.

Richard Mille (Richard Mille) is a new material proprietary to the watchmaking industry. Gray cermet combines the lightness of titanium and the hardness of ceramics. It is composed of a metal zirconium base related to high-performance ceramics, giving the material a single gray color. The production process is as extreme as the material itself. It is not easy to heat together and form such different materials at high temperatures without doping their respective masses and obtaining homogeneous materials, and because the composition avoids the hard material family that is usually The nickel and cobalt used are therefore more difficult. The material fully complies with REACH standards. After years of development in specialized laboratories, Richard Mille and Groupe IMI successfully eliminated these unwanted adhesives. Thanks to an innovative process that combines traditional hot stamping and a series of high voltage currents, only In this way, the kinetics of sintering can be enhanced. This technique is called rapid sintering.
The physical properties of cermet are widely recognized. Therefore, it is often used in reentry space shuttle components, external fuselage components, and brakes of racing vehicles in ballistic protection and aerospace. The mass-to-volume ratio of cermet is 4.1 g/cm3 and the hardness is 2360 Vickers hardness, which is comparable to other high-performance high-ceramics, making it very suitable for bezels. This area is extremely susceptible to scratches while ensuring that the entire assembly is lightweight weight.
The bezel is fixed on a strap made of carbon TPT, which also helps to reduce the total weight. This high-tech material consists of 600 layers of parallel filaments, which are obtained by separating carbon fibers. Layers with a thickness not exceeding 30 microns are impregnated with a black matrix. They are then assembled on a special machine that stacks the layers together and changes the direction between the fibers by 45°. The composite material is then heated in a kiln to 120°C at a pressure of 6 bar, similar to the kiln used to make aerospace parts, and then ready for mechanical processing at Richard Mille. The bottom cover is grade 5 titanium. The combination of these materials helps to significantly reduce the weight of the watch.
