World's thinnest automatic skeleton watch and thinnest automatic movement

Piaget Altiplano Automatic Skeleton for Only Watch 2013

Piaget is known, or rather famous, for its ultra-thin movements. Already 56 years ago, in 1957, Piaget introduced the thinnest mechanical movement ever to be created, caliber 9P, that is just 2 mm thick. Three years later, in 1960, Piaget introduced the thinnest automatically wound movement, caliber 12P, that measures a mere 2.3 mm. The Altiplano Automatic Skeleton for Only Watch 2013 holds two records in that field and it is fully skeletonized!

Two years ago, Piaget surprised everyone by donating a black PVD-coated version of the Altiplano Skeleton watch to the Only Watch auction. This year’s contribution is the automatic version, featuring a skeletonized version of caliber 1200P, which is the world’s thinnest automatically wound movement, with just 2.4 mm in height. The watch itself, measuring 5.34 mm, is still today’s thinnest watch with an automatically wound movement. That’s two records! The video presents these records in a visual way…

While the movement’s minimal thickness is already very impressive, all further adaptions are simply mind-boggling. Everyone who has visited a watch manufacture and has witnessed the meticulous hand-finishing on bridges, gears and other tiny parts, has at least an idea of how difficult and time-consuming this is. Now imagine how difficult it is to hand-bevel the edges of the ultra-thin bridges of caliber 1200S. Exactly, that’s unimaginable difficult and I’m sure that when I’d try it every single bridge would break in my hands.

The skilled watchmakers from Piaget apply sunburst satin-brushed finish to the bridges, hand-bevel the bridges, circular and sunburst finish the ultra-thin gears and all screw holes are angled and polished by hand, of course the screw heads are polished and even the slots of these tiny, tiny screws are polished by hand.

All that costs time, a lot of time, and extremely skilled hands. No wonder that a timepiece that is so thin and is hand finished to such a high degree, is no mass produced timepiece. When you know all this, a price of $60,000 USD for the Altiplano Automatic Skeleton doesn’t come as a shock. Although Antiquorum hasn’t given am estimate, I can imagine that it’ll be north of aforementioned list price.

Maybe not very clear on these photos, but the white gold case is black PDV-coated!
