Description
Within Richard Mille’s motorsport chronograph lineage, the RM50-03 represents the pinnacle of the brand’s collaboration with McLaren Formula 1, housing the most sophisticated split-seconds chronograph movement ever created by the manufacture. This 50mm x 44.5mm carbon case showcases the openworked dial architecture that reveals the mechanical poetry of the RM50-03 calibre, a movement that required over 5 years of development to achieve its unprecedented 70-hour power reserve while maintaining split-seconds chronograph functionality. The tonneau-shaped carbon case construction employs the same composite materials used in McLaren’s Formula 1 chassis, creating a horological instrument that weighs just 38 grams despite its substantial 50mm presence.
