RM 50-03 McLaren F1

Behind the scenes of the production of the world's lightest mechanical chronograph.

Produced in collaboration with McLaren, the new Richard Mille calibre offers off-the-chart mechanical performance. The RM 50-03 tourbillon split seconds chronograph ultralight McLaren F1 weighs less than 40 grams – including the strap – which makes it the lightest mechanical chronograph ever made. This landmark has been achieved through the use of cutting-edge technical materials. The design not only incorporates Titanium and Carbon TPTTM, but also introduces an entirely new material into the world of watchmaking: Graph TPTTM, more commonly known as graphene.
