Richard Mille created the thinnest mechanical watch in the world


Richard Mille together with Ferrari created the thinnest mechanical watch in the world, which costs more than some supercars of the Italian car maker. The model with the simple name RM UP-01 Ferrari costs $1.888 million. Only 150 units of this watch will be made.

As for its main feature, the thickness of the watch is only 1.75 mm! Yes, it is only 0.05 mm thinner than the previous record holder Bulgari Octo Finissimo Ultra, but in any case it is an incredibly thin device. At the same time, the thickness of the watch mechanism is even smaller — 1.18 mm. The watch is made mainly of titanium with inclusions of aluminum and vanadium. Richard Mille claims it took more than 6,000 man-hours to create the new product.


“Working collaboratively alongside the Ferrari team, the RM UP-01 is a model resulting from many year’s work, dozens of prototypes and more than 6,000 hours of development and laboratory testing. Meeting the challenge of an ultra-flat watch precluded a traditional movement with superimposed gears and hands.”


Richard Mille therefore opted to distribute what could not be stacked over a broader surface area by creating a perfect symbiosis between the movement and case, each ensuring the necessary rigidity of the other. The company was determined to retain a traditional architecture in which the movement is assembled within the case, rather than a construction in which the caseback doubles as a baseplate, in order to ensure under any circumstances total shock resistance.


Despite its ultra-slim case, the watch offers water resistance up to 10 m and is capable of withstanding accelerations of up to 5,000 g. The power reserve is declared up to 45 hours.
