World’s thinnest mechanical watch will cost over $20,000

A reported price of between $20,000 and $30,000 will buy you the world’s thinnest mechanical watch when it goes on sale. The Piaget Altiplano 900P is 3.65mm thick, a crucial 0.4mm thinner than the previous record holder, the Jaeger-LeCoultre Master Ultra-Thin Jubilee. As befitting a watch fancier than something called the Jaeger-LeCoultre Master Ultra-Thin Jubilee, Piaget’s new Altiplano 900P will be available in 18-karat white gold with a black alligator strap.

Swiss company Piaget has been making ultra-thin watches since 1957, and has been able to use expertise has helped it integrate the Altiplano 900P’s clockwork movement into the watch’s case for the first time. That movement is made up of 145 varying parts, each small and light enough to fit no more than 3.65mm away from the wearer’s wrist. The result is said to be impressively thin, but if thinness alone is your motivating factor in buying a watch, you might be better looking for digital models. The Piaget Altiplano 900P is still more than three times as fat as Central Standard Timing’s CST-01, an e-ink cuff-style watch only 0.80mm thick that reached its Kickstarter goal early this year.
