When it comes to men's timepieces, classic style is something of an asset. After all, just wearing a wristwatch says that you have a certain amount of respect for tradition and history. But that's not to say you can't stray from the beaten path a bit. Traditionally, the faces of a man's watch were black or white. Maybe silver. But lately, we've noticed watchmakers have been subbing in blue dials, resulting in a style that has a smart, sportier edge. The indigo faces, in nautical hues ranging from deep, dark navy to brighter cobalt, look just as refined and timeless as their black-and-white brethren, but have a slightly more relaxed feeling—the kind of watches that look right with your sleeves rolled up. So whether you're looking for an affordable option to strap on occasionally or a Swiss-made heirloom to wear everyday, here are six of the best available right now.
