My lustful fantasies generally lean toward custom road bikes, convertible sports cars, and vacations that require passports. But that was before I laid eyes on this watch. To say it's merely for telling time is like saying a ride from Waterford Precision Cycles is for getting around town. This particular Link, with its milky mother-of-pearl face, is inset with 72 sparkling diamonds weighing a collective 0.91 carats. The first time I fastened its sleek and sexy stainless-steel band around my wrist, I felt like I'd just slipped on one of Wonder Woman's indestructible wristbands. Time was suddenly mine. In addition to being drop-dead gorgeous—and far more useful than a diamond ring, which has no function other than to scream "I'm taken!"—this TAG has a one-tenth-second timer and is waterproof down to 650 feet. The only downside? I'll never again be able to blame tardiness on an inaccurate timepiece.
