"CREATING A WATCH FOR RAFAEL, THAT WOULD BECOME AS HE SAYS “A SECOND SKIN”, WAS A TREMENDOUS CHALLENGE FOR US. DISCOVERING THE OUTER LIMITS OF STRENGTH FOR THESE NEW MATERIALS, TESTING SUCH ULTRA-LIGHT TOURBILLON MOVEMENTS TO THE EXTREME ACCELERATION CONDITIONS OF HIGH LEVEL TENNIS MATCHES AND SUBJECTING THE CARBON COMPOSITE CASE TO AGING PROCESSES, SWEAT AND HEAT WAS A TOTAL NIGHTMARE FOR ME AND MY TEAM IN LES BREULEUX..."
Watchmaking must be consistently challenged, both technically and artistically. The RM 27-02 presents a new uncompromising caliber that reinterprets the art and methods of watch design in the 21st century.
The sculptural baseplate supports the bridges in grade 5 titanium, which are highly original in terms of their three-dimensional construction, their finishes and the complexity of their titanium and carbon composition. These bridges support an impressive mechanical heart capable of running for over 70 hours without detriment to its regularity thanks to a rapidly rotating barrel that delivers constant power from the beginning to the end of operation.
It is in the run-up to the 114th French Open, where emblematic Richard Mille partner Rafael Nadal will be vying for his tenth title, that the Swiss Jura brand is unveiling its new manual winding tourbillon caliber dedicated to tennis.
Limited edition of 50 pieces.
ARCING BRIDGES In grade 5 Titanium Beveled, shot-blasted and satin-brushed by hand.
FREE SPRUNG BALANCE WITH VARIABLE INERTIA A free sprung balance with variable inertia and a terminal-curve spring guarantees greater reliability in case of impacts and during movement assembly and disassembly, thus achieving better chronometric results over time.
UNIBODY BASEPLATE The baseplate, machined from NTPT® carbon, is an integral part of the case. For the first time at Richard Mille, the case middle has been removed. The bezel and case back are assembled directly on the baseplate, which is described as “unibody”, a type of racing-car construction that ensures maximum rigidity and greater resistance to impacts. The skeletonised NTPT® carbon baseplate is a feat of machining. A master component of the RM 27-02, it has been subjected to a full battery of extreme approval tests in order to optimize its mechanical properties.
CALIBER RM 27-02 Manual winding tourbillon movement with hours and minutes.
70 hours (±10%)
In sapphire (1800 Vickers) with anti-glare treatment (2 sides).
Thickness: 1.20 mm and 4.09 mm at the edges.
FAST ROTATING BARREL (6 hours per revolution instead of 7.5 hours)
This type of barrel has the following advantages:
- The phenomenon of periodic internal mainspring adhesion is significantly diminished and performance is thus enhanced, - It provides an excellent delta of the mainspring curve. The choice is determined by the ideal power reserve/
BARREL PAWL WITH PROGRESSIVE RECOIL
This device permits an appreciable winding gain (circa 20 %), especially during the start of winding. It also promotes the even distribution of the mainspring’s internal tension.
