Riley plays with proportion in a sophisticated way. Signature D-links interlock with a skinny bone leather strap and bold, round dial for a stylish look all its own. More accurate than a mechanical movement –this battery-powered watch sends energy through a quartz crystal. A multifunction is typically built into three separate dials for the day of the week, date of the month and 24-hour time. With a classic shape and sporty features, Riley is a style that transcends the season. This watch is compatible with all 18 mm straps.
