Close the steel bracelet around your wrist and feel the polished case settle into place, just over 1½" across. Before a lap swim or a brisk walk, rotate the colored bezel until its marker lines up with the minute hand, and a quick glance later tells you how long you’ve been at it.

Inside sits a Japanese Miyota automatic movement that keeps itself wound from the motion of your arm, so no battery ever needs replacing. Tighten the screw-down crown after setting the time and the case carries a 20 ATM water rating, which means a dip in the lake or the pool needn’t send it to the nightstand. The hour markers and hands glow softly, handy in a darkened theater or on an early drive.

Pick from five color pairings, from green over silver to black with gold accents. The double-layer dial gives the face real depth as the light shifts, and a 2-year warranty backs it. Wear it every day, and it does its own winding.
