The super-light, super-strong RM 50-03 is the result of an all-powerful collaboration between two giants of mechanical engineering
The worlds of horology and motor racing are closely intertwined. But while it’s common to see the names of watch brands emblazoned on the sides of cars, it’s more rare to see the two coming together to make a single product. Yet few can doubt the authenticity of the partnership between daring watchmaker Richard Mille and Formula 1 specialist McLaren, who have shared their considerable expertise to make a groundbreaking timepiece.
The deceptively chunky RM 50-03 weighs less than 40 grams – including the strap – making it the lightest mechanical chronograph ever made. This extraordinary feat is down to the incorporation of graphene into the case. The revolutionary nano-material, discovered by the University of Manchester, has never before been used in a watch design. It features properties that makes it six times lighter than steel while simultaneously being 200 times stronger – useful not only as a hard-wearing material for the wrist, but one that will play a key role in motor racing as McLaren works to integrate it into its Grand Prix cars.
“This gives us the relationships with academic institutions, such as the National Graphene Institute and other universities,” says Jonathan Neale, McLaren Racing CEO, of the company’s work in helping blend the material into the case structure. “We have an interest in material science, but also stand on the shoulders of those who are doing it. So we became early adopters.
