The “inverted” construction of the movement places the main functional elements on the dial side, with the offset micro-rotor and the quartz generator forming a figure eight,
while the off-center, pointed hour and minute hands sweep over finely tapered hour indices
Caliber 700P, for which Piaget has filed more than 10 patents, is the result of two years of research and development at the brand’s manufacture in La Cote aux Fees, Switzerland. It uses a high-frequency quartz element (32,768 vph, or roughly 5.33 turns per second) to control the rotation of the generator and wheel train of the mechanical, self-winding movement. The system ensures a high degree of precision as well as resistance to magnetic fields and gravity. Treated with a distinctive black coating, the movement boasts a number of haute horlogerie finishes: among these are the guilloché motif on the micro-rotor along with the Piaget coat of arms; sunburst and chamfered bridges; circular stain-brushed wheels; and silver-toned screws. The Piaget crest also appears as an engraving on the caseback, which allows just a glimpse into the inner heart of the watch with two small viewing windows
