PIAGET ALTIPLANO ULTIMATE CONCEPT WATCH
The Piaget Altiplano Ultimate Concept is the thinnest self-winding watch in the world, at only 2mm thickness. This is possible due to the watch's case that also acts as a base plate for the movement, in order to remove common components like a balance cock, shock absorber, and balance staff. It instead has a balance spring below the balance, a metal stud for adjustment, and a 0.2mm thick crystal. This watch is made from top-line "cobalt-based high tech alloy" for easier usability. Unfortunately, this watch is just a concept and not a physical reality yet.
