Following this technical feat and determined to continue challenging the very limits of fine watchmaking, Richard Mille RM 56-01 Tourbillon Saphire Replica Watch has created another exceptional piece for 2013: the RM 56-01 Sapphire Crystal. The brand used its immense experience of skeletonisation and of making components in sapphire crystal (Al 2O3), gained during research for both the RM 018 «Homage to Boucheron», which has a double baseplate in this material, and the case of the RM 056 for the creation of the RM 56-01, characterised by its extraordinary transparent movement.
The strap of the RM 56-01 alone inaugurates a new class of materials in watchmaking. Collaboration between Biwi SA and Richard Mille has made it possible to develop a material, Aerospace nano®, that employs nanotechnology to obtain unequalled transparency and strength. The nano-reinforcements in this material, which has never been used in watchmaking before, are generated in situ during the manufacture of Richard Mille RM 56-01 Replica Watch. Its elastic and waterproof properties make it silky to the touch and superbly comfortable.Its strap carries the concept of transparency to its apogee.
The caliber RM56-01, made from sapphire crystal and titanium, is immune to temperature variations and wear, ensures excellent stability and offers exemplary chronometric performance. This quest for extreme transparency at the heart of a titanium movement also led the engineers to use sapphire crystal for the central bridge and third wheel.By using a sapphire crystal baseplate – which supports the entire manually wound tourbillon movement – Richard Mille allows as much light as possible to penetrate into the caliber RM56-01, which displays the hours and minutes, with power-reserve and torque, at 11 and 2 o’clock respectively, and a function selector indicator at 4 o’clock.
In order to machine it, a specialist CNC machine had to be purchased especially for the RM 56-01. All the components made from sapphire crystal were machined by the world specialists in this material, Stettler, located in Lyss, Switzerland. Machining operations lasting for over 40 days, 24 hours a day, are required to produce one case.Its three-part case is inspired by that of the RM 056, with each component – front bezel, Richard Mille Replica Watch and back bezel – machined and ground from a solid block of sapphire crystal. This case, which sits perfectly on the wrist, is water-resistant to 30 metres thanks to two O-ring seals in transparent Nitril, and is fixed around the caliber RM56-01 using 24 grade 5 titanium spline screws.
This watchmaking revolution has elevated the Richard Mille Replica brand to an unrivalled level of design and innovation.When it was unveiled at the 2012 SIHH, the RM 056 split-seconds competition chronograph sapphire, a limited edition of 5 timepieces, caused a shock-wave in the watchmaking world with its pared down purity, its movement with exemplary finishing and its case made entirely of sapphire crystal.
