Let there be white with a watch that radiates clarity and cool (and lends a discreet luster to anything you wear). 1. A no-frills, number-free model is a simple way to clean up your act. Starck with Fossil, $125. 2. Sleek meets sporty with stylized numerals and a wave-patterned white leather strap. Montblanc, $1,310. 3. Your time is infinitely precious—a riveting stainless steel case studded with four diamonds proves the point. Baume & Mercier. 4. A stainless steel dual-movement timepiece with sapphire-coated dials and an interchangeable lizard strap has great curves. Philip Stein Teslar, $830. 5. An alligator strap and well-bred diamonds—not too big or glitzy—wrap your wrist in quiet luxury. David Yurman. 6. Burnish your already brilliant career in this icy model bordered with dazzling diamonds. Tag Heuer. 7. Pink-gold watch with signature nailheads (and three diamonds) is small but massively glamorous. Cartier.
