It wasn't so long ago that bigger was universally better in watches -- timepieces loaded up with chronographs, complications, and heavy metals. No more. The latest investment-grade models offer disarmingly simple designs, often classic styles from the past updated with subtle refinements. Think clean lines accentuated by large bezels, slim cases, and high-tech advances in materials and movements.
