Richard Mille used grey Cermet, a material that combines the lightness of titanium and the hardness of diamond, for the first time in the new RM 11-05 Automatic Flyback Chronograph GMT. A limited edition of just 140 pieces, the Richard Mille RM 11-05 Automatic Flyback Chronograph GMT in Grey Cermet has a price of Swiss Francs 200,000 excluding sales taxes.
Richard Mille’s quest for innovation does not slow down. This can be noted in advanced mechanical engineering solutions and new production methodologies but also in the use of unconventional and often unprecedented materials. The latest is grey Cermet. Combining the lightness of titanium and the hardness of diamond, this material has been used for the front bezel of the new RM 11-05 Automatic Flyback Chronograph GMT, a first in a Richard Mille timepiece.
Cermet’s physical properties are widely recognised, hence its frequent use in ballistic protections and in aerospace for re-entry shuttle components, exterior fuselage pieces and in the brakes on competition vehicles. Cermet has a hardness of 2,360 Vickers, comparable to other performance high-ceramic making it ideal for use in bezels, an area highly exposed to scratches.
Measuring 50 mm x 42.70 mm with a total thickness of 16.15 mm, the iconic case of the RM 11-05 also features a caseband in Carbon TPT and a caseback in grade 5 titanium (you can read more about these and other hi-tech materials used by Richard Mille here).
The combination of these three hi-tech materials helped to significantly reduce the weight of the RM 11-05. The complete case construction is water-resistant to 50 metres / 165 feet thanks to two Nitrile O-ring seals and is assembled using 20 spline screws in grade 5 titanium and 316L stainless steel washers.
Functions include: hours, minutes, seconds at 3 o’clock, annual calendar with month and oversize date, 24-hour flyback chronograph with minutes and countdown counters at 9 o’clock, hour counter at 6 o’clock, GMT function.
The oversize date display is placed in a red outlined horizontal aperture under 12 o’clock with automatic adjustment for months of 30 or 31 days. Indicated by Arabic numerals, the month display is placed between 4 and 5 o’clock.
Thanks to the flyback function, the running chronograph can be reset without first having to stop the mechanism by using the pusher between 4 and 5 o’clock.
While the chronograph function is activated, the hours and minutes show up the elapsed time thanks to the counter at 6 and 9 o’clock, the seconds are indicated by the central hands. At 9 o’clock, a skeletonised 60 minutes-marked disc replaces the hand. This way, the user can read elapsed minutes but also remaining minutes thus making a countdown.
Regarding the GMT function, the RM 11-05 uses an orange hand filled with Super-LumiNova. It can be easily adjusted using the pusher at 9 o’clock.
The baseplate and bridges of the skeletonised automatic winding Calibre RMAC3 are crafted of grade 5 titanium, a highly corrosion-resistant and rigid alloy which enables the gear train to function effortlessly. The alloy is 90% grade 5 titanium, 6% aluminium and 4% vanadium. This particular combination further increases the material’s mechanical properties. which explains its frequent use in the aerospace, aeronautics and automotive industries.
Beating at a frequency of 4 Hz (28,800 vph), the free-sprung balance with variable inertia guarantees greater reliability when subjected to shock and also during movement assembly and disassembly, hence better chronometric results over time.
The regulator index is eliminated and a more accurate and repeatable adjustment is possible thanks to 4 small adjustable weights located directly on the balance.
The rotor with variable geometry permits the rewinding of the mainspring to be adapted most effectively to the user’s activity level. By adjusting the setting of the rib’s placement, the rotor’s inertia is modified to either speed up or slow down the winding process depending on the lifestyle of the wearer. The rotor is crafted from titanium with a 18K white gold weight segment. The double barrel system guarantees 50 hours of power reserve.
