A direct descendant of the legendary 9P movement, the 438P is an ultra-thin hand-wound mechanical movement, measuring only 2.1 mm thick. Simple, sturdy and ultra-thin, the movement features central hour and minute functions. It is equipped with a balance stop. It perfectly exemplifies the attention Piaget accords to its finishes, with the traditional circular Côtes de Genève, the circular-grained mainplate and bridges, the bevelled bridges and the blued screws.
