CHECK THE TIME

While many people claim Paris and New York to be their favorite cities, the real test of such affection may be the purchase of one of Piaget’s special editions of its Tourbillon Relatif, part of the new Limelight Paris-New York collection. The Tourbillon Relatif houses Piaget’s most daring and complicated watch movement—a flying tourbillon with a regulating organ that is suspended above the dial and revolves with the minute hand once an hour around the center. But in this limited edition of just three watches (approximately $400,000) for each city, the mechanics are overshadowed by the decoration. Fields of blue-black Grand Feu enamel contrast with masterful engravings of city streets and monuments on the Paris version and New York’s distinctive skyline on its counterpart. The timepieces convey the charm and individuality of each city on a small-scale. (800.359.4538, www.piaget.com)
