Richard Mille RM 50-03 : CALIBRE RM50-03 - Manual winding tourbillon movement with hours, minutes, split-seconds chronograph, 30-minute totaliser, and power-reserve, torque and function indicators.
Produced in collaboration with the famed Formula 1 constructor, the RM 50-03 is a technical masterpiece offering unrivalled mechanical performance. Weighing less than 40 grammes including the strap, it was also the lightest mechanical chronograph ever made on its release.This landmark feat was achieved through the use of cutting-edge technical materials. The design not only incorporates Titanium and Carbon TPT®, but also introduces an entirely new material into the world of watchmaking: Graph TPTTM, more commonly known as graphene.
These new applications for the material emerged from research at the National Graphene Institute, which was established at The University of Manchester in 2015. Thanks to the collaborative efforts of The University of Manchester, McLaren Applied Technologies and North Thin Ply Technology (NTPT®), Richard Mille succeeded in producing a watch case that could be machined in an improved form of Carbon TPT®.
The 7-gramme movement, meanwhile, fully deserves its ‘ultralight’ qualifier. The secret to its feather-like weight resides in the use of grade 5 titanium and Carbon TPT® for the baseplate and bridges, and in the extreme skeletonisation of its components. Likewise, the density, rigidity and low thermal conductivity of titanium make it a material of choice in McLaren Racing’s Formula 1 engineering build programme, where it is not only used to lighten and reinforce chassis and aerodynamic elements, but also to produce gearboxes, connecting rods and valve systems.
