The feminine tuxedo style of the Limelight tonneau-shaped watch, which unfurls its elegant treasures on every occasion with its two rows of diamonds set either side of the white gold case. Its black ceramic crown perfectly matches its bracelet in black satin. On its iridescent white dial, fine black Roman numerals 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. Faithful to its motto "Always do better than necessary", Piaget embellishes this exclusive mechanism with traditional finishes, visible through the sapphire crystal case back: circular Côtes de Genève, circular-grained bottom plate and bridges, bevelled bridges and blued screws.
