Metiers d’Art Graffiti 18K rose gold watch with diamonds on alligator strap, Graff

Elevating its collector’s item status is the fact that it’s a one-of-a-kind piece designed by Takashi Murakami (he also created three other unique watches for the British jeweller). Featuring a whimsical mix of manga and traditional Japanese motifs, the dial was the result of detailed miniature painting using more than 10 colours, each manually blended for a customised hue.
