Richard Mille RM 50-03

Richard Mille is a brand commonly associated with advanced material technology and, of course, the signature tonneau case shape, and is often seen on the wrists of famous athletes like Rafael Nadal and members of the financial elite. Dubbed the lightest split-seconds chronograph tourbillon on the market, the RM 50-03, designed in collaboration with the McLaren F1 Team, weighs in at a mere 38 grams including the strap, thanks to the use of titanium, carbon, and a new material Richard Mille calls Graph TPT. It's a watch with a heaping helping of motorsport-inspired design language as well as some of the most avant-garde watchmaking technology in use today.
