Famous watch manufacturer Richard Mille has just unveiled a timepiece unlike any other to come before it. Dubbed the RM UP-01 and developed alongside Ferrari, it is the world’s thinnest mechanical watch.

The RM UP-01 is just 1.75 mm thick from dial to caseback, beating out the Bulgari Octo Finissimo Ultra by 0.05 mm as the world’s thinnest timepiece of its kind. The baseplate and bridges of the RM UP-01 are crafted from grade 5 titanium that also includes 6 per cent aluminum and 4 per cent vanadium. What’s more, the movement is just 1.18 mm thick, also a new record.

Richard Mille says it took over 6,000 man-hours to develop the RM UP-01. As part of this development, engineers created a titanium balance wheel and a unique escapement and safety roller to transfer energy to the balance wheel that ensures the timepiece can endure assembly, disassembly, and exposure to shock or strong vibrations.

The watch has a power reserve of 45 hours and while it may look quite delicate in photos, it is actually made to be worn and can withstand accelerations of over 5,000 Gs. It also offers 10 m of water resistance.

“The RM UP-01 Ferrari is an allusive piece to Ferrari’s values, developing sporting mechanisms that are as elegant as they are immediately recognizable,” Richard Mille described. “Their models make no concessions and frequently contradict current trends to create new aesthetical codes. The RM UP-01 Ferrari bears witness to this partnership of the best know-how these two iconic brands have to offer in the combination of their ideas, understanding, respective developments and shared values.”

Just 150 examples of the RM UP-01 Ferrari will be manufactured and as you may expect, it’s very expensive. Or rather obscenely expensive, as each carries a price tag of $1.888 million.
