The RM 50-03 Tourbillon Split Seconds Chronograph Ultralight McLaren F1 weighs less than 40 grams – including its strap – making it the lightest mechanical chronograph ever made. It’s a landmark that’s been achieved through the use of cutting-edge technical materials – titanium, carbon-fibre, and the introduction of an entirely new material into the world of watchmaking: Graph TPTTM, composed of Carbon TPTTM and a newly discovered material called graphene.

This revolutionary nano-material is six times lighter than steel, and 200 times stronger. McLaren’s investigations into the properties and applications of the material enabled Richard Mille to introduce it to the watch-making world.

Richard Mille, CEO of Richard Mille Watches, said:

“We couldn’t have dreamt of a more fitting partner in terms of image than McLaren. It’s an organisation that strives to achieve perfection – whether it be in research and development, aesthetics or execution, right down to the smallest detail. With our 10-year partnership, we’re really only at the beginning of exploiting the opportunities and know-how that exists between both our companies.”
