The RM 50-03 Tourbillon Split Seconds Chronograph Ultralight McLaren F1 weighs merely 38 grams, strap included, making it the world’s lightest split-seconds tourbillon chronograph. This lightness is achieved through the use of titanium and TPT™ Carbon creating an incredibly open design, using an entirely new material used for the case, Graph TPT™.

The bezel and caseback feature this groundbreaking material, a TPT™ Carbon whose physical properties have been considerably improved by the injection of graphene, a revolutionary nanomaterial six times lighter than steel but 200 times more resistant.

Produced in collaboration with the famed Formula 1 constructor, the RM 50-03 McLaren F1 Chronograph is a limited edition of 75 pieces. The RM 50-03 features a Caliber RM50-03 manual wind movement displaying hours, minutes, split-seconds, torque and function indicators for marking setting positions.
