new RM 50-03 Tourbillon Split Seconds Chronograph Ultralight McLaren F1


The new RM 50-03 Tourbillon Split Seconds Chronograph Ultralight McLaren F1 is the first product of a recently inked partnership between McLaren and high-end watchmaker Richard Mille. It was just unveiled this week at the Salon International de la Haute Horlogerie, the watchmaking equivalent of the Geneva Motor Show, and the same place where Breitling revealed its new connected watch for Bentley. Only where the Breitling has gone digital, the RM 50-03 is all about the craftsmanship and construction.

For starters, it's a tourbillon – the crown jewel of timekeeping complications that rotates the entire mechanism in its case at one revolution per minute, thereby negating the effect of gravity on a watch's accuracy, and obviating the need for a second hand in the process. It also features a split-second flyback chronograph function for tracking lap times, a 70-hour power reserve, and a torque sensor to protect the movement from over-winding. Yet the mechanism weighs only 7 grams and the entire watch just 40 – less than the weight of an egg or a tennis ball.


To make it that light, Richard Mille used not only titanium and carbon fiber, but also graphene. Six times lighter (yet 200 times stronger) than steel, the nano-material was discovered in 2004 at the University of Manchester, earning two professors there the Nobel Prize in physics. McLaren's Applied Technologies division has been working with the university's National Graphene Institute on applications for the substance, out of which Richard Mille constructed the three-part case, with the titanium and carbon-fiber movement at its center.

Richard Mille's timepieces typically sell for US$ 100k or more, and its tourbillons for half a million or so. The RM 50-03? It  reportedly costs almost as much as McLaren's P1 hybrid hypercar at a cool US$ 1 million excluding tax.
