I haven't seen guys wearing bracelets (but various kinds of strings and the like – that's cool).
But in general, I don't really like gold. At least because, among my acquaintances, with the exception of a former classmate, no one wears gold at all. I wouldn't want to stand out as a symbol of luxury.

Nah, what's the point of jewelry? It's better to have something useful, like a watch. Only if you need to show off wealth and the like, I guess.
Watches are great; I wear one all the time. :)
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
