Richard Mille RM 11-05 Automatic Flyback Chronograph GMT

·Gray Cermet, Richard Mille’s new exclusive material

·The lightness of titanium matches the hardness of diamond

It really comes to the spirit of Richard Miller that gray cermets are the result of research carried out through the tireless brand, which is a relentless commitment to the creation of new materials in its creation. The exclusive Richard Mille watchmaking material combines the lightness of titanium with the hardness of diamonds.

The structure of the self-winding movement makes titanium metal proud. Its functions include the GMT display, with the help of a 9 o’clock fader, 24-hour flyback chronograph and annual calendar, which can be easily adjusted. The added grey cermet is suitable for the pure aerodynamic lines of the iconic case, with a size of 50 x 42.70 mm and a total thickness of 16.15 mm.

The unique gray color of cermets is due 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 overall, because in order to comply with the REACH standard, the nickel and cobalt normally 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 IMI Group, which specializes in microtechnology, have removed these bad adhesives and only retained suitable materials. The innovative procedure used for this solution combines classic hot stamping with a series of powerful current pulses to improve sintering kinetics, a technique known as “rapid sintering”. Cermet has a density of 4.1 g/cm3 (lower than titanium alloys) and a hardness of 2360 Vickers (almost the same as 2400 Vickers for diamonds), making it a sensible choice for a bezel that is very suitable for scratches while maintaining overall brightness. The physical properties of cermets are widely recognized, so they are often used in bulletproof protection, external aerospace fuselage components, and brakes for racing vehicles.ladies watches

The combination of carbon fiber TPT strap, grade 5 titanium back cover and grey cermet bezel can significantly reduce the weight of RM 11-05.

Richard Mille (Richard Mille) is a brand new material exclusive to the watchmaking industry. The gray cermet combines the lightness of titanium with 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 and form this different material together at high temperature without doping their respective qualities and obtain a homogeneous material, and because the composition avoids the usual hard material family The use of nickel and cobalt is therefore more difficult. The material fully complies with the REACH standard. After years of development in specialized laboratories, Richard Mille and Groupe IMI have successfully eliminated these unwanted adhesives, thanks to an innovative process that combines traditional hot stamping with a series of high-voltage current bursts, thus Only the required materials are retained, so that the sintering kinetics can be enhanced. This technique is called rapid sintering.

The physical properties of cermets are widely recognized, so they are often used in ballistic protection and aerospace for reentry into space shuttle components, external fuselage components, and brakes for racing vehicles. 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 ceramics. It is very suitable for bezels. The area is extremely easy to scratch, while ensuring the entire assembly is lightweight and lightweight.

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. The layer with a thickness not exceeding 30 microns is impregnated with a black matrix. They are then assembled on a dedicated machine that stacks the layers together, changing the direction between the fibers by 45°. The composite material is then heated in a kiln at a pressure of 6 bar to 120°C, similar to the kiln used to manufacture aerospace parts, and then ready to be machined at Richard Mille. The bottom cover is grade 5 titanium. The combination of these materials helps to significantly reduce the weight of the swiss watch men.

With the help of two Nitrile O-rings, the entire housing structure is water resistant to 50 meters and is installed in grade 5 titanium alloy and 316L stainless steel washers using 20 spline screws.
