RM 50-03

We couldn’t have dreamt of a more fitting partner than McLaren. The brand strives to achieve perfection—whether it be in research and development, aesthetics or execution, right down to the smallest detail. With our ten-year partnership, we are really only at the beginning of exploiting opportunities and transfers of know-how between our two companies. Yet the collaboration has already borne fruit with the RM 50-03, the lightest mechanical chronograph ever produced.

Produced in collaboration with the famed Formula 1 team, the RM 50-03 is a technical masterpiece offering off-the-chart mechanical performance. The split seconds chronograph ultralight McLaren F1 weighs merely 38 grams, strap included, making it the world’s lightest split-seconds tourbillon chronograph. This achievement is attributable to the use of highly technical materials: not only do titanium and Carbon TPT® make for an extremely open design, but an entirely new material has been introduced for the case, namely Graph TPT®.
