Richard Mille RM UP-01 Ferrari Ultraflat Titanium

The RM UP-01 Ferrari is 1.75 mm thick, the product of the partnership Richard Mille and Ferrari began in 2021, and the brand insists it is a watch to wear rather than a concept, validated to the same standards as its others. Richard Mille says it took more than 6,000 hours of development and testing. There was no room to stack gears under hands, so the movement is spread across the case, and the case and movement stiffen each other. The Grade 5 titanium case is 51 mm across and rated to only 10 m, and the hand-wound RMUP-01 inside runs for 45 hours. It is limited to 150 pieces, and Richard Mille gives the price only on request.
