The cushion-shaped calibre 700P, the first Piaget self-winding movement with high-precision generator, places quartz technology at the service of an iconic ultra-thin Piaget movement that inverts the traditional watchmaking design codes. It pays tribute to the ultra-thin 7P quartz watch presented by the Maison in 1976, then the thinnest in the world with a thickness of 3.1 mm. Measuring just 5.5 mm in thickness, the 700P mechanical movement boasts a 32,768 Hz high frequency regulation that controls the running of the movement. Beyond superior precision, the calibre 700P resists magnetic fields as well as gravity. Its inverted architecture reveals the main functional elements of the watch on the dial side, the off-centred generator and the platinum oscillating weight which create a harmonious figure 8. The hours and minutes, also off-centred, are displayed at 5 o'clock, while the power reserve indicator may be read on the case back. The finishes of the black-treated movement pay tribute to watchmaking tradition: a guilloché microrotor, sunray-finished and chamfered bridges, satin-brushed circular wheels and silver-finish screws.
