RM 11-05 automatic flyback chronograph GMT Its cermet case combines the lightness of titanium with the hardness of diamonds

The case material of the new RM 11-05 Automatic Flyback Chronograph GMT is made of gray cermet and is the result of in-depth research. Unique to Richard Mille watchmaking, this material combines the lightness of titanium with the hardness of diamond. replica Richard Mille McLaren 

However, the construction of the automatic movement leaves the honorary position to titanium. Its functions include, inter alia, a GMT display easily adjustable using the push-button at 9 o'clock, a 24-hour flyback chronograph and an annual calendar. Gray cermet blends harmoniously with the pure aerodynamic lines of the legendary case, which measures 50 x 42.70 mm and has an overall height of 16.15 mm.

The unique gray color of cermets is due to the combination of a metallic zirconium matrix and high-performance ceramics. Its implementation is as challenging as the fabrication of the materials themselves, and heating and pressing these two very different materials at high temperatures without affecting their respective qualities is a challenge. Obtaining a homogeneous whole is made more difficult because the nickel and cobalt commonly used in this family of hard materials do not comply with REACH standards that guarantee the production and use of industrial chemicals in Europe. buying replica watch 

After several years of development, Richard Mille and Groupe IMI, which specializes in microtechnology, have managed to eliminate these unwanted adhesives and retain only the suitable materials. The innovative process that provides this solution combines classic hot pressing with a series of powerful current pulses to enhance sintering dynamics, a technology called "discharge plasma sintering." With a density of 4.1 g/cm3 (lower than titanium) and a hardness of 2,360 Vickers (almost as high as diamond's 2,400 Vickers), it is recommended to use cermets on bezels and other areas that are particularly susceptible to scratches to preserve the Lower overall weight.

The physical properties of cermet are widely recognized, which explains why it is often used in ballistic protection, aerospace exterior hull components and racing brakes. The combination of Carbon TPT® case middle, grade 5 titanium backplate and gray cermet bezel help to significantly reduce the weight of the RM 11-05. replica Jacob and Co. astronomia 

Technical features of the RM 11-05 automatic flyback chronograph GMT

Case: Dimensions 50.00 x 42.70 x 16.15 mm.

The bezel is made of gray cermet, the case middle is made of Carbon TPT®, and the case back is made of grade 5 titanium. Gray cermet is a new watchmaking material specially created for Richard Mille, combining the lightness of titanium with the hardness of ceramic. A metallic zirconium matrix combined with high-performance ceramics gives the material its unique gray color.

The process of making it is as impressive as the material itself. Heating and joining these disparate materials at high temperatures without affecting their individual properties and creating a homogeneous material is not easy. The task is even more complicated because the composition shouldn't contain any nickel or cobalt, which are commonly used in this family of hard materials. The material is fully compliant with REACH regulations. After years of development in specialist laboratories, Richard Mille and Groupe IMI have succeeded in eliminating these unwanted adhesives, retaining only suitable materials. quality replicas watches 

This is achieved through an innovative process that combines traditional hot pressing with a series of strong current pulses, thereby enhancing sintering kinetics. This technology is also called spark plasma sintering.

The physical properties of cermet are internationally recognized, which explains its frequent use in ballistic protection, re-entry spacecraft components and external airframe components in the aerospace sector, and in brakes for racing cars. With a density of 4.1 g/cm3 and a hardness of 2,360 Vickers, it is comparable to other high-performance ceramics, which predestined the use of cermets in the bezel area that is particularly susceptible to scratches, while maintaining the watch's Lightweight. Overall construction.

The bezel is fixed in the middle of the case made of Carbon TPT®. The high-tech material consists of more than 600 layers of parallel filaments, which are formed by separating carbon fibers.

The layers, which have a maximum thickness of 30 microns, are impregnated with a black matrix and then assembled by a special machine that changes the direction of the fibers by 45°. Carbon TPT® is ready for further processing at Richard Mille after being heated to 120°C in an oven at 6 bar pressure, similar to those used in aerospace production. The case back is made of grade 5 titanium. The combination of these materials significantly contributes to reducing the weight of the replica watch stores .

The entire case structure uses two nitrile O-ring seals and is assembled from 20 grade 5 titanium spline screws and 316L stainless steel wear-resistant washers, making it water-resistant to 50 meters.

Height Ring: Made of carbon fiber; filled with approved luminescent material.

Crown: Finely sandblasted grade 5 titanium with double O-ring seal and Alcryn® coating.

Dial: Sapphire crystal (height: 0.40 mm), anti-reflective coating on both sides, protected by 8 silicon clips embedded in upper and lower grooves.

Crystal: Bezel side: Sapphire crystal (1,800 Vickers hardness) with anti-reflective coating (both sides), Height: 1.50 mm.

Case back: sapphire crystal with anti-reflective coating (double-sided), height: center 1.20 mm; outer edge 2.04 mm.

Movement: CALIBRE RMAC3, self-winding skeleton movement, hour, minute and second hands at 3 o'clock, oversized date, month, flyback chronograph, minute counter at 9 o'clock, hour counter at 6 o'clock clock position, GMT function and variable geometry rotor.

Power reserve approximately 50 hours (±10%). Actual power reserve results depend on when and how often the chronograph is triggered.

Plates and bent tubes made of grade 5 titanium

Cleats and bridges are made of grade 5 titanium. This biocompatible, extremely corrosion-resistant and very strong alloy enables gear trains to function optimally. The alloy is composed of 90% grade 5 titanium, 6% aluminum and 4% vanadium. This combination further improves the material's mechanical properties and is therefore often used in the aerospace and automotive industries. RMAC3 caliber plates are optimized to achieve an ideal and extremely low weight/strength ratio. The skeleton panels and bridges undergo intensive and comprehensive validation testing to optimize their durability. replica Grand Seiko Watches 


Flyback chronograph: Pressing the pusher between 4 and 5 o'clock resets a running chronograph without first stopping the mechanism. This feature was originally developed for pilots who did not want to lose time (and thus accuracy) by stopping, resetting and starting the chronograph when passing landmarks. When the chronograph function is activated, the timers at 6 o'clock and 9 o'clock display the elapsed hours and minutes, while the central hand is responsible for timing. Usage: The user can start or stop the chronograph function via the button between 1 o'clock and 2 o'clock.

The flyback function for zeroing can be activated at any time using the pusher between 4 o'clock and 5 o'clock.

Countdown: The hand at 9 o'clock has been replaced by a skeletonized disc with a 60-minute mark. Users can read not only the elapsed minutes but also the remaining minutes.

GMT Function: The RM 11-05 features GMT hands with Super-LumiNova coating. Easily adjusted using the push-button at 9 o'clock.

Extra-large date display: Semi-instantaneous display in a red-line horizontal aperture below 12 o'clock, automatically recognizing months with 30 or 31 days.

Month display: semi-instantaneous display, indicated by Arabic numerals between 4 o'clock and 5 o'clock.

Free-oscillating balance with variable moment of inertia: This type of balance represents the highest level of innovation. It provides greater reliability in the event of a shock and when assembling and disassembling the movement, and improves long-term accuracy. The return hand has been eliminated, replaced by four small adjustable weights directly on the balance wheel, allowing for more precise and repeatable adjustment.

Richard Mille's unique design allows the winding of the mainspring to be adjusted effectively to the wearer's activity level, whether in sports or otherwise. The inertia of the rotor can be changed by positioning the blades. This way, the elevator requires very little movement of the arms and hands to speed up, or slow down during intense movements. Thanks to this development, the movement's winding mechanism can be optimized and personalized to suit the wearer's lifestyle.

Dual barrel system: This system helps achieve greater torque stability over a longer period of time. The increased number of revolutions reduces friction and stress on the teeth, bearings and journals, improving long-term performance.
