The World’s Thinnest Mechanical Wristwatch

The Richard Mille RM UP-01 Ferrari is the world’s thinnest mechanical wristwatch, at just 1.75 millimeters thick. While its frame may be diminutive, its price tag is anything but. At a whopping $1.88 million, the watch is crafted from Grade 5 titanium and features an ultra-thin mechanism. Designed in collaboration with watchmakers Audemars Piguet and Renaud & Papi, the internal mechanism that makes the watch tick is a mere 1.18 millimeters thick. The design is unconventional to be sure, with time being displayed by a very small register in the center of the top half of the watch, with the circle next to it offering a view of the balance. The two smaller circles on the left side of the watch are used for accessing the movement. The watch is waterproof to a depth of 32 feet and can reportedly withstand accelerations of more than 5,000 G’s. It’s also incredibly light, with the internal mechanism weighing less than an ounce. In terms of looks, the watch isn’t for everyone, but when it comes to craftsmanship and ingenuity, the RM UP-01 Ferrari constitutes a triumph of technical prowess.
