At first it seemed that becoming a scratch golfer would be easier than learning to use the Boucheron Chronogolf, a new watch that electronically records hole-by-hole scores and automatically calculates whether you are under or over par. But five minutes spent reading the instructions and learning how to use the pair of pushpieces flanking the time-set knob brought a childish delight as the hands swung around after each input to show—well, just how bad things were. A one-of-a-kind watch for the golfer who has everything. $4,450. 877-715-7330.
