The feminine dinner-jacket style of the Limelight tonneau-shaped watch, which unfurls its elegant treasures on every occasion with its two rows of 86 diamonds set either side of the white gold case. On its white mother-of-pearl dial, slender black Roman numerals and hour-markers mark the passing hours to the rhythm of the 438P calibre, an ultra-thin hand-wound mechanical movement that is only 2.1 mm thick. Piaget has embellished this exclusive mechanism with traditional finishes, visible through the sapphire crystal case back: circular Côtes de Genève, circular-grained main plate and bridges, bevelled bridges, and blued screws.
