The 1205P movement has an off-center small seconds dial at 5 o'clock and a date display at 9 o'clock, the traditional Piaget Manufacture signature. The world's thinnest automatic winding movement with date measures just 3 mm, a record for its category. All Piaget's ultra-thin watchmaking expertise is brought into play, the movement's components are slimmed down and the spaces between them reduced to the minimum. The components have been shaped to make the movement as thin as possible, some wheels being as little as 0.12 mm in thickness. The oscillating weight, in 22-carat rose gold, has been miniaturized and mounted off-center so as to be fully integrated in the thickness of the movement. This distinctive mode of construction required extremely complex calculations to determine the weight distribution that would ensure optimum winding. This ultra-thin movement boasts outstanding Manufacture finishes. The bridges are beveled and decorated with the circular Côtes de Genève, the mainplate is circular-grained and the screws blued. The 1205P movement also features sunburst wheels and a special regulator bearing the Piaget "P" signature.
