You can’t make time stand still, so why should your watch be stagnant? Swiss artist Karl Gerstner designed carpe diem for Rado so you’ll never get bored looking down at your wrist: The entire face pattern changes by the second, and no single pattern repeats itself within a year. Only 2002 carpe diems will be sold. The watch is made of a ceramic bezel with a black cotton strap and retails for $1,400. www.rado.com
