Richard Mille RM 63-02 World Timer Replica Watch

Richard Mille's novelty

Richard Mille collaborated with Airbus Business Jet (ACJ) to demonstrate an automatic ultra-thin 7.75mm timepiece and two new RM 011 declination angles.Richard Mille RM 67-01 Automatic Extra Flat

Movement RM50-02: manual winding tourbillon movement with hours, minutes, seconds chronograph and running seconds, 60-minute totalizer, power reserve, torque and function indicator

Dimensions: 50.10 x42.70 x16.50mm
Power reserve
About 70 hours (± 10%), displayed as a number near 11 o'clock.
Skeletonized titanium matrix

The baseplate has been made of grade 5 titanium, which is a biocompatible, highly corrosion-resistant and very hard alloy that allows easy operation of the gear train.
The alloy is 90% grade 5 titanium, 6% aluminum and 4% vanadium. This combination further improves its mechanical properties, which explains its frequent use in the aerospace, aviation and automotive industries.Harry Winston Histoire de Tourbillon

The bottom plate of the RM50-02 movement is optimized to achieve an extremely high weight / resistance ratio.

Bridge made of grade 5 titanium and stainless steel

The bridge of the RM50-02 movement is made of grade 5 titanium alloy. In order to make the movement have a greater depth, some bridges are made of stainless steel and have a golden appearance after being coated with aircraft.

Secondary split mechanism to improve performance
One of the new features developed for the second hand tourbillon RM 50-02 is to almost completely eliminate the initial beating of the chronograph second hand. In addition, the development of a new generation of second hand assembly means that by reducing the friction in the movement and eliminating the inertial jump of the chronograph hands during stopping and starting, the energy consumption of this function can be reduced by about 50%. This is achieved through research focused on the work of the second hand arm.replica Urwerk watches

Operation: Press the button on the right side of 4 o'clock, the user can stop the minute hand to read the intermediate time when using the chronograph. Press the button again and the second hand will rejoin the chronograph to prepare for the next measurement.

Torque indicator
This indicator provides information about the tension of the mainspring, which optimizes the timing function of the movement. Below 53 dNmm, the spring is considered too loose, while above 65 dNmm,

Excessive spring tension may adversely affect the operation of the mechanism and may even endanger the operation of the mechanism. (These indicators appear on the digital area near 2 o'clock).

Function indicator
In a manner similar to a car gearbox, the function indicator allows people to see the winding, neutral, and pointer setting positions when pulling out the crown. Each position is indicated by a pointer at 4 o'clock, showing the following functions: W (winding) – N (neutral) – H (pointer).

Balance wheel with variable inertia
This type of balance wheel ensures higher reliability when it is impacted and during assembly and disassembly of the movement, thereby obtaining better timing results over time. The indexing is eliminated, so 4 positioning screws can be used for more precise and repeatable adjustments.replica watches luxury

Quick spin barrel (6 hours per revolution, not 7.5 hours)
This type of barrel has the following advantages: periodically reduces the sticking phenomenon of the internal spring, thereby significantly improving performance, providing an excellent clockwork delta curve, and having an ideal power reserve / performance and regularity ratio.

Progressive recoil bucket
This device allows significant winding gain (approximately 20%), especially at the beginning of the winding. It also helps to evenly distribute the internal tension of the mainspring.

Wound tooth and third wheel pinion with central involute profile

Wheels with a center spread profile and a 20 ° pressure angle can more effectively promote rolling motion, compensate for differences between centers, ensure excellent torque transmission, and significantly improve performance.


Modular time setting mechanism for watch case
Provides the following advantages for service life and maintenance: Since the component is installed outside the movement, the time setting component can be changed without affecting the integrity of the bottom plate during possible failure or maintenance. Installing and removing the module from the back does not require removing the hands and dial.

Grade 5 titanium spline screws for bridges
This allows better control of the torque applied to the screw during assembly. Therefore, these screws are not affected by physical operations during assembly or disassembly, and can be aged well.https://www.chrono36.com
