The new RM UP-01 collaboration with Ferrari packs a full working movement into a case just 1.75mm thick.

Earlier this year, Bulgari held the record with its 1.8mm-thick Octo Finissimo Ultra, but the reign was short-lived.

The new watch is made from grade 5 titanium that is harder, stronger, and 40% lighter than steel.

A special winding tool is needed to set the time and power up the mainspring with up to 45 hours of reserve.

All internal components are machined to a tolerance of a single micron, or .001 millimeters…

The result is a water- and shock-resistant watch that can be worn for most normal uses, albeit with a very small dial.

The manufacturing run is limited to 150 pieces, and each watch will cost $1.88 million.

That’s considerably more than the $440,000 for Bulgari’s offering, but only ten of those will be sold.

Like Richard Mille's other offerings, the UP-01 is sure to be a conversation starter.
