• F1 stars Carlos Sainz and Charles Leclerc have new Richard Mille watches as part of a partnership between the watchmaker and Ferrari.
• Only 150 will be made, and if you want one it will cost you $1.88 million.

A pair of Formula One stars have a new accessory, and if you want one, it will set you back $1.9 million.

Luxury watchmaker Richard Mille announced its newest watch, the RM UP-01 Ferrari, the thinnest watch ever made at just 1.75 mm.

The watch is the latest piece coming out of the partnership between Richard Mille and Ferrari, which began in 2021. Only 150 of these watches will be made, and according to Hodinkee.com, they will have a retail price of $1.88 million.

The watch's case, base plate, and bridges are made of Grade 5 titanium, a material used in the aerospace and aeronautics industries, and can withstand forces up to 5,000 Gs.

Richard Mille and its watches are no strangers to the sports world.

Golfer Bubba Watson wears a Richard Mille watch when he plays. The 2018 version had a retail price of $825,000 and could measure his swing speed.

Rafael Nadal also sports a Richard Mille watch when he competes. The version he wore during the 2018 French Open had a price of $725,000.

While F1 drivers can't wear their watches during the races, they are always quick to put them on before their post-race interviews. Considering how often Leclerc and Sainz have been on the podium this season, the new Richard Mille watch should get plenty of screen time moving forward.
