Richard Mille - Carbon TPT® - RM 50-03 CB

The RM 50-03 tourbillon split seconds chronograph ultralight McLaren F1 weighs less than 40 grams – including the new strap – which makes it the lightest mechanical chronograph ever made.   McLaren Applied Technologies and North Thin Ply Technology (NTPT®), Richard Mille has succeeded in producing a watch case machined in an improved form of Carbon TPT™. The carbon’s physical properties were significantly enhanced by the introduction of graphene, a revolutionary nano-material which is six times lighter than steel, and 200 times stronger. McLaren Technology Group and McLaren-Honda, which are currently working on integrating graphene into their Grand Prix cars, made it possible for us to consider this material as a means to significantly low the density of our carbon composite while increasing its resistance. Convinced of the incredible advantages conferred by graphene, our engineers worked with those at North Thin Ply Technology to envision practical applications of the new material, and studied how to incorporate it into Carbon TPT™.
