The release in 2012 of the RM 056 - Felipe Massa in a limited edition of five was an event in terms of watchmaking innovation. Its price was about $ 1.7M. The three pieces that make up the case of this split-seconds chronograph watch are transparent with an absolute clarity, allowing the user to see from any angle the movement of the tourbillon.
The transparent material is a sapphire crystal, resistant to any scratch. The machining and polishing of a sapphire piece takes several hundred hours. The use of titanium is extended to all mechanical components and to the baseplate. The case is water resistant to 50 meters.
Evolution has already gone forward. The RM 56-01 has its baseplate and its third hand in sapphire. RM 27-01 - Rafael Nadal and RM 56-02 incorporate a further improvement in the suspension of the movement on the baseplate. At its release in 2014 the price of the RM 56-02 was about $ 2M.
On June 21 in New York, Christie's sells the prototype No. 2 of the RM 056, lot 228 estimated $ 1M. The number of prototypes realized for that model has not been disclosed.
SOLD for $ 1.2M including premium
