Direct descendant of the legendary 12P movement, the 1200P is one of the thinnest self-winding mechanical movements in the world. To achieve the thinness of 2.35 mm, the watchmaker, Piaget relied on all of its ultra-thin expertise and trimmed down all of the movement's components. Some of the gears in the 1200P have been reduced to only 0.12 mm, hardly thicker than a human hair, and the space between the wheels has been reduced to a minimum of only 0.1 mm. It is also equipped with a balance stop. In order to make the best use of space, the precious micro-rotor, decorated with the Piaget coat-of-arms is off-centred and positioned at 9 o'clock on the movement. As part of Piaget’s constant effort to differentiate its models, it has decorated the wheels of the 1200P movement with a sunburst motif and its index assembly carries the stylised P of Piaget like a secret signature. The circular Côtes de Genève, the circular-grained mainplate, the bevelled bridges, the oscillating weight engraved with the Piaget coat-of-arms as well as the blued screws add the finishing touches to this exceptional movement, while remaining true to the aesthetic codes cherished by the Swiss watchmaking brand.
