Haute Horologerie and Haute Joaillerie are Piaget's traditional fields of expertise. Representing the most symbolic horological complication, interpreted in a skeletonised version, the tourbillion is combined here with an original case set with diamonds. Piaget plays on lightness and transparency in a skeletonised version of its famous Emperador Tourbillion. Like the equally gem-set bridges, this version calls for exceptional know-how. This Emperador model represents the world's only gem-set skeleton tourbillion. The Emperador case provides an elegant setting for the world's thinnest shaped tourbillion, a mere 3.5mm thick. The complication most representative of the watchmaking art is interpreted in a highly original way in this model with a carriage positioned at 12 o'clock. Made up of 42 parts, it barely weighs 0.2 grams. Calibre 600P is endowed with a power-reserve indicator.
