For a long time, we've been advocates of a wedding ring and watch being the only jewelry a man should wear. And although we still think you should avoid anything with expensive stones, fake stones, earnings, pinky rings, bling, or dog tags if you haven't served in the military, we've warmed up to the idea of the simple bracelet. Giles & Brothers make some really good looking and masculine ones for around $100.
Miansai also makes some good ones, but they're a little bit more expensive. Either are a great option, though.
