The lightness of titanium alloy blends with diamond-like hardness

The brand-new Grey Cermet material adheres to the spirit of RICHARD MILLE. It is not only the result of the brand's painstaking research, but also fully reflects its persistence in creating new materials. The unique proprietary material used by RICHARD MILLE has both the lightness of titanium alloy and the hardness of diamonds. Its density is 4.1g/cm3-lower than titanium alloy-hardness of 2,360 Vickers hardness-almost comparable to the 2,400 Vickers hardness of diamond-making cermets very suitable for making bezels that are very susceptible to scratches, while giving overall weight Keep it light.


RMAC3 movement

Skeleton self-winding movement, hour and minute display, stopwatch at 3 o'clock, large date window and month display, flyback chronograph function, minute counter and countdown timer at 9 o'clock, at 6 o'clock Positioned hour counter, coordinated universal time (GMT) function and variable geometry oscillating weight.

Power reserve

Approximately 55 hours (± 10%), approximately 45 hours with the chronograph activated.
The actual power reserve time is determined by the number of times the stopwatch is used.

Grade 5 titanium alloy base plate and bridge plate

The bottom plate and bridge plate are made of grade 5 titanium alloy, which has excellent biocompatibility and corrosion resistance. It is an excellent cemented carbide that allows the gear transmission system to operate smoothly and efficiently. This alloy is composed of 90% titanium, 6% aluminum and 4% vanadium. This combination can optimize the mechanical properties of metals, so it is often used in aerospace and automotive manufacturing. The bottom plate of the RMCC3 movement has been optimized to achieve a good balance of weight/resistance.

The hollow bottom plate and bridge plate have been thoroughly and intensively tested to optimize their strength.

Flyback timing

By using the button located between 4 o'clock and 5 o'clock, the wearer can reset the chronograph without stopping the chronograph in advance. This feature was originally designed for pilots to save time (and ensure accuracy) in the process of stopping the timer, resetting the stopwatch to zero, and restarting a new timer when crossing the sailing point.
After the chronograph function is activated, the time counters at 6 o'clock and 9 o'clock will display the elapsed hours and minutes, and the seconds will be displayed by the central hands.

Oscillating weight characteristics

• Five grade titanium alloy swing arm
• High palladium content 18K white gold oscillating weight outer ring
• The outer ring of the oscillating weight can be adjusted in 6 positions with grade 5 titanium alloy screws
• Ceramic ball bearings
• One-way rotation, anti-clockwise winding
This creative design of RICHARD MILLE can effectively adjust the power of the mainspring according to the wearer's activity habits, such as whether the wearer is in a sports environment. Adjust the inertia of the rotor by adjusting the six-position setting of the wings. Therefore, if the wrist swings less frequently, the movement will speed up the winding speed, and if the wearer performs strenuous exercise, the winding speed will slow down.
