Crowning over half a century of virtuosity in the field of the ultra-thin, the hand-wound mechanical movement 900P is the result of a totally innovative design, in which the case back also serves as a bottom plate for the movement driven by 145 components. As a result, the case housing the 900P boasts a record thinness of 3.65 mm. This most complex of architectures involves the reverse construction of the movement, with the bridges raised on the dial side. In a rare technical feat, the suspended barrel, attached by only one bridge boasts a power reserve of 48 hours. All the components are meticulously decorated in the finest watchmaking tradition, while the index-assembly bearing the "P" of Piaget crowns the world's thinnest mechanical movement.
