Last but not least, Piaget watchmakers present an ultra-jewelled version of the famous cushion-shaped Black Tie watch, made famous by one of the most loyal Piaget Society customers, Andy Warhol. The piece combines a petrified wood dial with a bezel and markers made of baguette-cut emeralds. This unique piece is powered by the Manufacture’s extra-thin mechanical calibre 534P, the spark that ignites the fire.
