The appeal of a watch completely encrusted in gems is obvious—but a face full of gems leaves little room to tell time. Christian Tse has solved this problem with the Prismatic timepiece collection, his fi rst foray into watches. Each piece features a full-frontal assault of glitz—diamonds, tsavorites, amethysts and sapphires, in some instances forming motifs such as the Union Jack or a heart—through which a digital LED time display shines at the touch of a button. They range in price from $7,900 to $19,000 and soon will include custom options. The inspiration behind the 30-piece collection was simple enough: “I had wanted to light up diamonds in jewelry,” Tse says.
