The Charming Bird Everything about this watch is a delight, but the eyes are naturally drawn to the songbird, which has been meticulously hand-decorated by artisans. The mechanism allows the bird to rotate, open and close, flap its wings and ruffle its tail feathers. Even more impressive is its ability to whistle. Jaquet Droz reportedly developed the chime based on early wind instruments. This piece has a 47mm white-gold case and an automatic mechanical movement. Limited to 28 pieces.
