Question: What do Jackie Kennedy, Elizabeth Taylor and Andy Warhol have in common, apart from irrepressible charisma and style? Answer: Each of them had stunning Piaget watches of their own.

The luxury brand is holding an exhibition at the Piaget Time Gallery in the Mandarin Oriental Hong Kong until September, and among the many watches and jewellery showcased are the three stunning pieces owned by the style icons.

Jackie Kennedy's diamond and emerald watch sparkles next to Elizabeth Taylor's ornate cuff watch (pictured), while Warhol's table clock looks sleekly cool, incorporated into a solid gold bar.
